Medieval Japanese literature

Japan's medieval period (the Kamakura, Nanbokuchō and Muromachi periods, and sometimes the Azuchi–Momoyama period) was a transitional period for the nation's literature. Kyoto ceased being the sole literary centre as important writers and readerships appeared throughout the country, and a wider variety of genres and literary forms developed accordingly, such as the "gunki monogatari" and "otogi-zōshi" prose narratives, and "renga" linked verse, as well as various theatrical forms such as "noh". Medieval Japanese literature can be broadly divided into two periods: the early and late , the former lasting roughly 150 years from the late 12th to the mid-14th century, and the latter until the end of the 16th century.
The early saw a continuation of the literary trends of the classical period, with court fiction ("monogatari") continuing to be written, and composition of "waka" poetry reaching new heights in the age of the "Shin-kokin Wakashū", an anthology compiled by Fujiwara no Teika and others on the order of Emperor Go-Toba. One new genre of that emerged in this period was the "gunki monogatari", or war tale, of which the representative example of "The Tale of the Heike", a dramatic retelling of the events of the wars between the Minamoto and Taira clans. Apart from these heroic tales, several other historical and quasi-historical works were produced in this period, including "Mizu Kagami" and the "Gukanshō". Essays called "zuihitsu" came to prominence with "Hōjōki" by Kamo no Chōmei and "Tsurezuregusa" by Kenkō. Japanese Buddhism also underwent a reform during this period, with several important new sects being established, with the founders of these sects—most famously Dōgen, Shinran, and Nichiren—writing numerous treatises expounding their interpretation of Buddhist doctrine. Writing in classical Chinese, with varying degrees of literary merit and varying degrees of direct influence from literature composed on the continent, continued to be a facet of Japanese literature as it had been since Japanese literature's beginnings .
The late saw further shifts in literary trends. "Gunki monogatari" remained popular, with such famous works as the "Taiheiki" and the "Soga Monogatari" appearing, reflecting the chaotic civil war the country was experiencing at the time. The courtly fiction of early eras gave way to the "otogi-zōshi", which were broader in theme and popular appeal but generally much shorter in length. "Waka" composition, which had already been in stagnation since the "Shin-kokin Wakashū", continued to decline, but this gave way to new poetic forms such as "renga" and its variant "haikai no renga" (a forerunner to the later haiku). The performing arts flourished during the late medieval period, the "noh" theatre and its more informal cousin "kyōgen" being the best-known genres. Folk songs and religious and secular tales were collects in a number of anthologies, and travel literature, which had been growing in popularity throughout the medieval period, became more and more commonplace. During the late 16th century, Christian missionaries and their Japanese converts produced the first Japanese translations of European works. "Isoho Monogatari", a translation of "Aesop's Fables", remained in circulation even after the country largely closed itself off to the west during the Edo period.
Overview.
Japan's medieval period lasted roughly 400 years, from Minamoto no Yoritomo's establishment of the Kamakura shogunate and being named shōgun in the third year of the Kenkyū era (1192) to Tokugawa Ieyasu's establishment of the Edo shogunate in Keichō 8 (1603) following the Battle of Sekigahara in 1600 that began the Edo period. This period, based on the centres of political power, is normally divided into the Kamakura, Nanbokuchō (or Yoshino), Muromachi and Azuchi–Momoyama periods, and is also referred to simply as the Kamakura-Muromachi period. The start date of this period has also been taken as being around 1156 (the Hōgen rebellion) or 1221 (the Jōkyū rebellion), with the Azuchi–Momoyama period also sometimes being taken as part of the early modern period, with the medieval period ending at Oda Nobunaga's entry to the capital in Eiroku 11 (1568) or the end of the Ashikaga regime in Tenshō 1 (1573).
The period is characterized by war, beginning with the Genpei War and ending with the Battle of Sekigahara, with other conflicts such as the Jōkyū rebellion, the war between the northern and southern courts and the Ōnin War (1467–1477), culminating in the entire country erupting in war during the Sengoku period. The social order was disrupted as a result of these conflicts, with changes to society in general and, naturally, shifts in literary styles and tastes. The philosophy of impermanence (無常 "mujō") became pervasive, with many seeking salvation, both physical and spiritual, in religion, specifically Buddhism.
Aesthetic ideals.
The basic ideal that informed aesthetic tastes in this period is known as "yūgen" (roughly meaning "mystery" or "depth"), along with other concepts such as "ushin" (有心, literally "possessing heart", the more "weighty" or "serious" poetry, as opposed to games) and "yōen" (妖艶, literally "ethereal beauty"). These ideals shunned realism, representing a spirit of "l'art pour l'art" and aiming to plunge the reader into an "ideal" world, and were in accord with the ideals of Buddhist monastic seclusion (出家遁世 "shukke-tonsei"). What exactly constituted "yūgen" differed throughout its history, and the various literary genres it influenced include "waka" ("Japanese poetry", meaning poetry in vernacular Japanese, typically in a 5-7-5-7-7 metre), "renga" ("linked verse") and the "noh" theatre.
Later developments include "en" (艶, literally "lustre" or "polish"), "hie" (ひえ) and "sabi" (roughly "stillness" or "attenuation"), connecting to the literature of Japan's early modern period. Translator and literary historian Donald Keene discusses both "yūgen" and "hie" (which he translated "chill") as concepts shared by the quintessentially medieval art forms of "renga" and "noh". He describes "sabi" as having been "used to suggest the unobtrusive, unassertive beauty that was the ideal of Japanese poets, especially during the turbulent decades of the Japanese ", and states that it first came to prominence around the time of the "Shin-kokin Wakashū".
There was, however, a concurrent trend toward a form of realism in medieval developments on the concept of "okashi" (をかし; "bright", "happy", "charming", "humorous" or "brilliant"). Authors began to attempt to reflect reality in order satirize social conditions, or for simple enjoyment.
Authors and readership.
Medieval Japanese literature is most often associated with members of the warrior class, religious figures and hermits (隠者 "inja"), but the nobility maintained a degree of their former prestige and occupied an important position in literary circles. This was especially true in the early (i.e., the Kamakura period), when court literature still carried the high pedigree of earlier eras, while monks, recluses and warriors took an increasingly prominent role in later centuries. Furthermore, at the very end of the medieval period (i.e., the Azuchi–Momoyama period), urban ("chōnin") literature began to appear. As a result, the medieval period was the time when the literature of the nobility became a truly "national" Japanese literature.
Developments in the performing arts allowed for large groups of people to appreciate literature on a broader level than before. As the social classes that had previously supported the arts fell away, new groups stepped in as both creators and audiences for literary works. These conditions encouraged the growth of a literature that was more visual and auditory than the literature of Japanese classical period. This is true of performing arts like "noh" and traditional dance, but also includes such genres as the "emakimono", picture scrolls that combined words and images, and "e-toki", which conveyed tales and Buddhist parables via images.
The centre of culture continued to be the capital in Kyoto, but other areas such as Ise and Kamakura became increasingly prominent as literary centres.
Literature of the early medieval period.
Historical background of the early medieval period.
The early medieval period covers the time between the establishment of the Kamakura shogunate and the shogunate's collapse roughly 140 years later in Genkō 3 (1333). With the shogunate, who were of warrior stock, controlling the affairs of state in eastern Japan, the aristocracy of the Heian court continued to perform limited court functions and attempted to preserve their aristocratic literary traditions. The first two or three decades, which are also known as the "Shin-kokin" period, saw a surge in interest in "waka" composition and attempts to revive the traditions of the past. However, with the failure of the Jōkyū rebellion and Emperor Go-Toba's exile to Oki Island, the court lost almost all power, and the nobility became increasingly nostalgic, with the aristocratic literature of the later Kamakura period reflecting this.
As the warrior class was in its ascendancy, their cultural and philosophical traditions began to influence not only political but also literary developments, and while literature had been previously the exclusive domain of the court this period saw a growth in the literature of other levels of society. Narrative works such as "The Tale of the Heike" are an example of this new literature.
Buddhism was also in its heyday during this period, with new sects such as Jōdo-shū, Nichiren-shū and Zen-shū being established, and both old and new sects fervently spreading their influence among the populace throughout the country. In addition to Buddhist literature such as "hōgo", the monks of this period were especially active in all manner of literary pursuits. Those who became hermits upon entering Buddhism produced a new kind of work, the "zuihitsu" or "essay", as well as fine examples of "setsuwa" ("tale") literature. Such literature is known as hermit literature (隠者文学 "inja-bungaku") or "thatched-hut literature" (草庵文学 "sōan-bungaku").
Overall, the literature of this period showed a strong tendency to combine the new with the old, mixing the culture of aristocrats, warriors and Buddhist monks.
Early medieval "waka".
The "waka" genre of poetry saw an unprecedented level of exuberance at the beginning of the Kamakura period, with Emperor Go-Toba reopening the Waka-dokoro in Kennin 1 (1201). Notable, and prolific, poets at the highest levels of the aristocracy included Fujiwara no Yoshitsune and his uncle, the Tendai abbot Jien. At both the palace and the homes of various aristocrats, poetry gatherings ("uta-kai") and competitions ("uta-awase") such as the famous ' and ' were held, with numerous great poets coming to the fore. On Go-Toba's command, Fujiwara no Teika, Fujiwara no Ietaka and others compiled a new "chokusenshū" (imperial "waka" anthology), the "Shin-kokin Wakashū", which was seen as a continuation of the grand "waka" tradition begun three hundred years earlier with the "Kokin Wakashū". , in his article on medieval literature for the "Nihon Koten Bungaku Daijiten", calls this the final flowering of the aristocratic literature, noting its high literary value with its basis in the literary ideals of "yūgen" and "yūshin", its emphasis on suggestiveness, and its exquisite delicacy.
The foundations for this style of poetry were laid by Teika and his father Shunzei, not just in their poetry but in their highly regarded works of poetic theory ("karon" and "kagaku-sho"). These include Shunzei's ' (also valuable as an exploration of the history of "waka") and Teika's ' and "Kindai Shūka" (近代秀歌). Such works had a tremendous influence on later "waka" poets, and their philosophy of "fūtei" (風体, "style") has had value for Japanese aesthetics and art generally. Other works of poetic theory include those that are noted for their recording of various anecdotes about "waka" poets, including Kamo no Chōmei's "".
This flourishing was characteristic of the first three or four decades of the Kamakura period, but following the Jōkyū rebellion and the exile of Go-Toba, the great patron of "waka", the genre went into decline. Teika's son, Fujiwara no Tameie, championed simplicity in "waka" composition, writing the "karon" work "Eiga no Ittei". In the generation following Tameie, the "waka" world became divided between schools represented by the three great houses founded by Tameie's sons: Nijō, Kyōgoku and Reizei. The conservative Nijō school, founded by Tameie's eldest son, was the most powerful, and with the different schools supporting different political factions (namely the and the ), there was less emphasis on poetic innovation than on in-fighting, and the genre stagnated.
The compilation of imperial anthologies, though, actually became more frequent than before, with a ninth anthology, the "Shin-chokusen Wakashū", and continuing on regularly over the following century until the sixteenth, the "Shoku-goshūi Wakashū". Of these eight, the only one that was compiled by a member of the Kyōgoku school was the "Gyokuyō Wakashū", compiled by Kyōgoku Tamekane, and this is considered the second best of the Kamakura anthologies after the "Shin-kokin Wakashū". Every other collection was compiled by a Nijō poet, and according to Ichiko there is little of value in them. However, in eastern Japan the third shōgun, Minamoto no Sanetomo, a student of Teika's, showed great poetic skill in his personal anthology, the "", which shows the influence of the much earlier poetry of the "Man'yōshū".
Overall, while poetic composition at court floundered during the Kamakura period, the courtiers continued the act of collecting and categorizing the poems of earlier eras, with such compilations as the "" and the "Mandai Wakashū" (万代和歌集) epitomizing this nostalgic tendency.
"Monogatari".
Works of courtly fiction, or "monogatari" (literally "tales"), continued to be produced by the aristocracy from the Heian period into the Kamakura period, with the early Kamakura work "Mumyō-zōshi", written by a devout fan of "monogatari", particularly "The Tale of Genji", emphasizing literary criticism and discussing various "monogatari", as well as "waka" anthologies and other works by the court ladies. The work praises "Genji" and then goes on to discuss various works of courtly fiction in roughly chronological order, and is not only the sole work of such literary criticism to survive from this period but is also valuable for detailing the history of the genre.
The "Fūyō Wakashū" is a slightly later work that collects the "waka" poetry that was included in courtly fiction up to around Bun'ei 8 (1271). This work was compiled on the order of Emperor Kameyama's mother Ōmiya-in (the daughter of Saionji Saneuji), and shows not only the high place courtly fiction had attained in the tastes of the aristocracy by this time, but the reflective/critical bent with which the genre had come to be addressed in its final years. Well over a hundred "monogatari" appear to have been in circulation at this time, but almost all are lost. Fewer than twenty survive, and of the surviving works, several such as "Sumiyoshi Monogatari", "Matsuranomiya Monogatari" and "Iwashimizu Monogatari" (石清水物語) have unusual contents. Other extant "monogatari" of this period include ', ', "" and "Ama no Karumo" (海人の刈藻).
Late Kamakura works of courtly fiction include ', ' and ', and these works in particular show a very strong influence from earlier works, in particular "The Tale of Genji", in terms of structure and language. Long works of courtly fiction at this time were almost all ' ("pseudo-archaic" tales, works imitative of past "monogatari"), and production of them largely ceased during the Nanbokuchō period.
Early medieval "rekishi monogatari" and historical works.
Works that continued the tradition of Heian "rekishi monogatari" ("historical tales") such as "Ōkagami" ("The Great Mirror") and "Ima Kagami" ("The New Mirror") were written during this period. "Mizu Kagami" ("The Water Mirror"), for example, recounts the history of Japan between the reigns of Emperor Jinmu and Emperor Ninmyō, based on historical works such as the "Fusō Ryakuki".
"Akitsushima Monogatari" (秋津島物語) attempted to recount events before Jinmu, in the age of the gods.
More serious historical works composed during this period include the "Gukanshō", which describes the period between Emperor Jinmu and Emperor Juntoku. It also attempted to describe the reasons for historical events and the lessons to be learned from them, and unlike the historical romances being produced at court that reflected nostalgically on the past, the "Gukanshō" used history as a way to criticize present society and provide guidance for the future. It is also noteworthy for its simple, direct language, which was a new innovation of this period.
Early medieval "gunki monogatari".
The historical and court romances were a continuation of the works of the Heian period, but a new genre that built upon the foundations laid by these emerged in the Kamakura period: the "gunki monogatari" (warrior tale), which is also known as simply "gunki", or "senki monogatari". The immediate predecessors of these works were "kanbun" chronicles composed in the Heian era such as the ' and ', as well as warrior tales included in the "Konjaku Monogatari-shū".
The "gunki monogatari" emerged in the early medieval era as a form of popular entertainment, with the most important early works being the "Hōgen Monogatari", the "Heiji Monogatari", and "The Tale of the Heike". These three recounted, in order, the three major conflicts that led to the rise of the warrior class at the end of the Heian period. They were composed in "wakan konkō-bun", a form of literary Japanese that combined the "yamato-kotoba" of the court romances with Chinese elements, and described fierce battles in the style of epic poetry. They portrayed strong characters proactively and forcefully, in a manner that Ichiko describes as appropriate for the age of the warrior class's ascendancy. The "Heike" in particular was widely recited by "biwa-hōshi", travelling monks, usually blind, who recited the tale to the accompaniment of the "biwa", and this was a very popular form of entertainment throughout the country all through the .
The authors of these works are largely unknown, but they were frequently adapted to meet the tastes of their audiences, with court literati, Buddhist hermits, and artists of the lower classes all likely having a hand in their formation. There are, consequently, a very large number of variant texts. In addition to the largely unprecedented manner in which these works were formed, they led to the rise of the " style of musical accompaniment.
Following these three, the ", which recounted the events of the Jōkyū rebellion, was also compiled. Together, the four are known as the "Shibu Gassen-jō" (四部合戦状). The "Soga Monogatari", which was composed toward the end of this period, placed its focus on heroic figures, and laid the foundations for the "gunki monogatari" of the Muromachi period.
Some "gunki monogatari" in this period took the form of picture scrolls.
Early medieval "setsuwa" literature.
Similarly to new the innovations in the collection and categorization of "waka" poetry in the Kamakura period, the period saw an upswing in the compilation and editing of "setsuwa", or short tales and parables. This included aristocratic collections such as the "Kokon Chomonjū", the "Kojidan" and the ', as well as the "Uji Shūi Monogatari", which also incorporates stories of commoners. Other works targeted at members of the newly ascendant warrior class had a stronger emphasis on disciplined learning and Confucianism, as exemplified in the '.
Buddhist "setsuwa" works were meant to provide resources for sermons, and these included the ' of and Kamo no Chōmei's ', the "" and "Shiju Hyakuin Nenshū" (私聚百因縁集). Of particular note are the works of monk and compiler Mujū Dōgyō, such as "Shaseki-shū" and "Zōdan-shū" (雑談集), which mix fascinating anecdotes of everyday individuals in with Buddhist sermons.
These "setsuwa" collections, like those of earlier eras, compile tales of Buddhist miracles and the nobility, but works like the "" also incorporate tales and anecdotes from China, and some include tales of commoners, showing a change in tastes in this new era.
Some works describe the origins of Buddhist temples and Shinto shrines and collect tales of miracles. Such works include the "Kasuga Gongen Genki" and the "", both of which are "emakimono" that combine words and images. These are a development of the earlier "engi" that were written in "kanbun", but Ichiko classifies them as a form of "setsuwa".
Early medieval diaries, travel literature and essays.
Ladies at court continued to write diaries as they had during the Heian period, with important examples including ' and '. Of particular interest are diaries written by women who became ' (court ladies) during the Taira ascendancy such as "Kenshun-mon'in Chūnagon Nikki" and ', which provide a glimpse of life behind the scenes at the palace.
The latter in particular, written by Kenrei-mon'in Ukyō no Daibu who had come to court to serve Kenrei-mon'in, is focused primarily on poetry that conveys her sadness and lamentation, following the downfall of the Taira clan in warfare, which shows a character quite different from the ladies' diaries of the Heian period. "Towazu-gatari", a work by Go-Fukakusain no Nijō, combines reflections on her time serving at court with a travelogue. It provides a bare-faced look at the inner thoughts and desires of its author, which is rare for a work written by a woman of this period, causing Ichiko to compare it to the I novel.
Literary diaries written in Japanese by men, such as Asukai Masaari's "Haru no Miyamaji" (はるのみやまぢ, also known as 飛鳥井雅有日記 "Asukai Masaari Nikki") began to appear. The tradition of "kanbun-nikki" (diaries in classical Chinese) used to record the day-to-day lives of the nobility also continued, of which Teika's "Meigetsuki" is the best-known example.
Because of the biregional nature of government in this period, with the court in Kyoto and the shogunate in Kamakura, works describing the journey along the Tōkaidō between Kyoto and Kamakura, such as ', ', and the nun Abutsu's "" began to appear "en masse". "Kaidōki" and "Tōkan Kikō" were written by highly educated men in "wakan konkō-bun".
"Takakura-in Itsukushima Gokōki" (高倉院厳島御幸記) is one important example of the growing subgenre of travelogues describing pilgrimages to shrines and temples. "Ryūben Hōin Saijōki" (隆弁法印西上記) recounts the Tsurugaoka Hachimangū "bettō" 's journey to Onjō-ji and the time he spent there. It was likely composed by one of Ryūben's travelling companions, and is noteworthy partly for its unusual gaps in describing the journey, and for its frank portrayal of the perversity of the monks.
Works discussing the rejection of the material world, beginning with Saigyō at the end of the previous era, continued to be composed in the Kamakura period. These works combined poetry describing the recluse life in thatched-hut retreats with magnificent essays called "zuihitsu". The most important examples are Kamo no Chōmei's "Hōjōki" and Kenkō's "Tsurezuregusa" which were written around the very end of the Kamakura period and the beginning of the Nanbokuchō period. The former describes its author's journey toward giving up the world, social changes, and celebrates recluse life, while the latter is a work of instruction detailing its author's inner thoughts and feelings as he lives in quiet seclusion. Along with the classical "Pillow Book", they are considered the archetypal Japanese "zuihitsu".
Buddhist literature and songs.
While many of the works described above have Buddhist themes, "Buddhist literature" here refers to a combination the writings of great monks of the various Japanese Buddhist sects and the collections of their sayings that were produced by their followers. These include:
Many of these Buddhist writings, or "hōgo", expound on deep philosophical principles, or explain the basics of Buddhism in a simple manner that could easily be digested by the uneducated masses.
In addition to the continued production of ', "sōka" (早歌) were created in large numbers, and their lyrics survive in textual form. Buddhist songs were performed as part of ', etc., and of particular note is the "wasan" form. Many of these "wasan" were supposedly created by Buddhist masters of the Heian period, but the form became prominent in the Kamakura period. These songs were composed with the goal of educating people about Buddhism, and were widely recited around the country. Ichiko writes that the songs themselves are moving, but that Shinran's "Sanjō Wasan" and later songs were particularly brilliant works of Buddhist literature.
Furthermore, "engi" associated with famous temples, and illustrated biographies of Japanese Buddhist saints such as "Kōya-daishi Gyōjō Zue" (高野大師行状図絵), "Hōnen-shōnin Eden" (法然上人絵伝), "Shinran-shōnin Eden" (親鸞上人絵伝), "", continued to be produced during the Kamakura period and well into the Nanbokuchō period. Ichiko categorizes these as examples of the Buddhist literature of this period.
Literature of the late medieval period.
Historical background of the late medieval period.
The late medieval period covers the roughly 270 years that, by conventional Japanese historiography, are classified as the Nanbokuchō (1333–1392), Muromachi (1392–1573) and Azuchi–Momoyama (1573–1600) periods. The conflict between the northern and southern courts in the Nanbokuchō period, and the frequent civil wars in the Muromachi period, caused massive social upheaval in this period, with the nobility (who were already in decline) losing virtually all of their former prestige, and lower classes moving upward to take their place. In particular, the high-level members of the warrior class took over from the aristocracy as the custodians of culture.
The literature of this period was created by nobles, warriors, and hermits and artists of the lower classes. The popular literature and entertainment, which had previously been of little consequence, came into the limelight during this time. The "noh" theatre came under the protection and sponsorship of the warrior class, with Kan'ami and his son Zeami bringing it to new artistic heights, while Nijō Yoshimoto and lower-class "renga" (linked verse) masters formalized and popularized that form.
This is the point when "ancient" literature came to an end and was replaced with literature more representative of the early modern period. This results in some degree of schizophrenia in the literature of this period, as contradictory elements are mixed freely. Deep and serious literature was combined with light and humorous elements, which is a noteworthy characteristic of late medieval literature. "Noh" and its comic counterpart "kyōgen" is the standard example of this phenomenon, but "renga" had "haikai", "waka" had its "kyōka" and "kanshi" (poetry in Classical Chinese) had its "kyōshi". "Monogatari-zōshi" composed during this period combined the "aware" of the serious "monogatari" with characteristics of humorous anecdotes.
Literature characterized by "wabi-sabi" was valued during this period of chaotic warfare. Commentary on and collation of the classics also came to the fore, with the "hidden traditions" of "Kokinshū" interpretation ("") beginning. Furthermore, it was during this period that the classical Japanese literary tradition ceased to be the exclusive prerogative of the aristocracy, and passed into the hands of scholarly-minded warriors and hermits. Ichijō Kaneyoshi and were noteworthy scholars of aristocratic origins, and in addition to writing commentaries such aristocratic scholars examined and compared a large volume of manuscripts. This opening up to the general populace of classical literature was also advanced by hermit "renga" masters such as Sōgi.
Ichiko notes that while this reverence for the literature of the past was important, it is also a highly noteworthy characteristic of this period that new genres and forms, unlike those of earlier eras, prevailed. He also emphasizes that even though this was a period of bloody warfare and tragedy, the literature is often lively and bright, a trend that continued into the early modern period.
Literature in Chinese.
Classical Chinese ("kanbun") literature of the Heian period had been the domain of aristocratic men, but as the aristocracy fell from prominence writing in Chinese became more closely associated with Zen Buddhist monks. Zen monks travelling back and forth between Japan and China brought with them the writings of Song and Yuan China, and writing in Chinese by Japanese authors experienced something of a renaissance.
The Chinese literature produced during this period is known as the literature of the Five Mountains because of its close association with the monks of the Five Mountain System. The founder of the lineage was Yishan Yining ("Issan Ichinei" in Japanese), an immigrant from Yuan China, and his disciples included Kokan Shiren, Sesson Yūbai, Musō Soseki and others; these monks planted the seeds of the Five Mountains literary tradition. Kokan's "Genkō Shakusho" is an important work of this period. Ichiko remarks that while Chūgan Engetsu also created excellent writings at this time, it was Musō's disciples Gidō Shūshin and who brought the literature of the Five Mountains to its zenith. Keene calls the latter two "masters of Chinese poetry", describing Zekkai as "the greatest of the Five Mountains poets".
Musō and Gidō in particular had the ear of powerful members of the military class, to whom they acted as cultural and spiritual tutors. The tradition continued to flourish into the Muromachi period, when it came under the protection of the shogunate, but this led to its developing a tendency toward sycophancy, and while there continued to be exceptional individuals like Ikkyū Sōjun, this period showed a general tendency toward stagnation and degradation. Nevertheless, Ichiko notes, the literature of the Five Mountains had a profound impact on the cultural and artistic development of the Nanbokuchō period.
Late medieval "waka".
Four imperial anthologies were compiled during the Nanbokuchō period: three by the Nijō school and one, the "Fūga Wakashū", by the Kyōgoku school. The latter was directly compiled by retired emperor Kōgon, and has the second greatest number of Kyōgoku poems after the "Gyokuyō Wakashū". The "Shin'yō Wakashū", a quasi-"chokusenshū" compiled by Prince Munenaga, collects the works of the emperors and retainers of the Southern Court.
In the Muromachi period, the "waka" composed by the nobility continued to stagnate, and after compiled the "Shinshoku-kokin Wakashū", the twenty-first imperial anthology, the age of court "waka" was at its end.
The most important "waka" poets of this period were not courtiers but monks, hermits, and warriors. Examples of prominent monk-poets are the Nijō poet Ton'a in the Nanbokuchō period and Shōtetsu (who wrote the book of poetic theory "") and (who was also a noted "renga" master) in the Muromachi period. Important "waka" poets of the samurai class include Imagawa Ryōshun in the early period, (said to be the founder of the "kokin-denju" tradition) and others toward the middle of this period, and Hosokawa Yūsai at the very end of the . Yūsai carried the "waka" tradition on into the early modern period, an act whose significance, according to Ichiko, should not be underestimated.
"Renga".
Linked verse, or "renga", took the place of "waka" as the dominant poetic form during this period. "Renga", or more specifically "chō-renga" (長連歌), emphasized wit and change, and was practiced in earlier times by both the nobility and commoners, but during the Nanbokuchō period Nijō Yoshimoto organized gatherings of both nobles and commoners and with the assistance of hermits like was able to formalize the "renga" tradition and compile the first true "renga" anthology, the "Tsukuba-shū". Yoshimoto also composed important books of "renga" theory such as "Renri Hishō" and "Tsukuba Mondō" (筑波問答).
Later came notable poets like , but "renga" went into a brief period of stagnation until the Eikyō era (1429–1441), when the favour of the shōgun Ashikaga Yoshinori led to its being rejuvenated. The Seven Sages of the Bamboo Grove (竹林の七賢), including such masters as and Shinkei were at their height during this period. Shinkei, who was also a prominent "waka" poet, wrote works of "waka" and "renga" theory such as "Sasame-goto" and "Hitori-goto". Sōgi, who was active from roughly the time of the Ōnin War, built on these developments and helped "renga" to reach its highest point. With he compiled the "Shinsen Tsukuba-shū", and with his disciples and create "renga" masterpieces such as "Minase Sangin Nannin Hyakuin" (水無瀬三吟何人百韻) and "Yuyama Sangin" (湯山三吟).
Sōgi's disciples Sōchō, Sōseki , and other's carried on his legacy, teaching others and continuing the glory days of the genre. The most important "renga" master of the end of this period was , who wrote "Renga Shihō-shō" (連歌至宝抄). He continued the practice of expanding "renga" to the masses, with his family (the Satomura clan) continuing to play a central role in the "renga" world into the Edo period. Under his influence, "renga" became fixed, causing it to stagnate, and leading to the increased popularity of "haikai no renga".
"Haikai" had been popular even in the golden age of "renga", but went on the rise beginning with "Chikuba Kyōgin-shū" (竹馬狂吟集), the Ise priest Arakida Moritake's "Haikai no Renga Dokugin Senku" (俳諧之連歌独吟千句, also known as "Moritake Senku" 守武千句) and Yamazaki Sōkan's "" ("Haikai Renga-shō" 俳諧連歌抄) in the late Muromachi period. "Haikai" developed from "renga" at roughly the same time as "kyōka" developed from "waka". Some "haikai", according to Ichiko, ventured too far into absurdity, but they tapped into the popular spirit of the Japanese masses, and laid the groundwork for the major developments of the form in the early modern period.
"Monogatari-zōshi".
The "giko-monogatari" of the earlier period largely ceased during the Nanbokuchō period, and an incredibly large number of shorter works known as "monogatari-zōshi" (more commonly called "otogi-zōshi", a name that was applied later) were created. Many of them are unsophisticated and childish, and were written for a much broader audience than the earlier tale literature, which had been written by and for the aristocracy exclusively. As a result, they cover a much broader range of topics, and were written not only by nobles but by warriors, monks, hermits and urbanites.
Of the works that continued the courtly tradition, some (such as "Wakakusa Monogatari") told romantic love stories and some (such as "Iwaya no Sōshi") contained stories of unfortunate stepchildren. Among those about members of the warrior class, some (such as "Shutendōji") drew upon "gunki monogatari" and heroic legends of monster-slayers, some (such as "Onzōshi Shima-watari") built legends of warriors, and others (such as "Muramachi Monogatari" and "Akimichi") told of chaos between rival houses and revenge. A very large number of them are about religious themes, reflecting the rise of popular Buddhism during this period. Some of these works (such as "Aki no Yo no Naga Monogatari") described monastic life, some (such as "Sannin Hōshi") expounded the virtues of seclusion, some (such as "Kumano no Honji") elaborate on the origins of temples and shrines in light of the concept of "honji suijaku" ("original substances manifest their traces", the concept that the gods of Shinto are Japanese manifestations of Buddhist deities), and some (such as "Eshin-sōzu Monogatari") are biographies of Buddhist saints.
In addition to the above works about nobles, warriors and monks, there are also a number of works in which the protagonists are farmers and urban commoners, known as "risshin-shusse mono" (立身出世物, "tales of rising up in the world") and "shūgi-mono" (祝儀物). Examples of the former include "Bunshō-zōshi" (文正草子) and examples of the latter include "Tsuru-Kame Monogatari" (鶴亀物語). A number of these works are based on popular folk-tales, and reflect themes of "gekokujō" and the lively activity of the lower classes. Several feature settings outside Japan, including the "engi-mono" of the early period and such works as "Nijūshi-kō" (二十四孝) and "Hōman-chōja" (宝満長者).
A number of works, called "irui-mono" (異類物) or "gijin-shōsetsu" (擬人小説, "personification novels"), include anthropomorphized plants and animals, and these appear to have been very popular among readers of the day. Examples of this group include war stories like "Aro Gassen Monogatari" (鴉鷺合戦物語, lit. "The Tale of the Battle of the Crow and the Heron"), love stories like "Sakura-Ume no Sōshi" (桜梅草子), and tales of spiritual awakening and living in monastic seclusion such as "Suzume no Hosshin" (雀の発心), while some, such as "Nezumi no Sōshi" (鼠の草子), portray romance and/or marriage between humans and anthropomorphized animals, and such works were widely disseminated. These works, along with tales of slaying monsters (怪物退治談 "kaibutsu-taiji tan"), appear to have been popular in an age when weird and creepy tales (怪談 "kaidan (literature)" and 奇談 "kidan") proliferated.
The short prose fiction of this era, as elaborated above, differed drastically from the courtly fiction of early ages in its variety. More than 500 were written, and many come down to us in manuscript copies that include beautiful coloured illustrations. It is believed that these works were read aloud to an audience, or were enjoyed by readers of varying degrees of literacy with the help of the pictures. They represent a transition between the courtly fiction of earlier times to the novels of the early modern period.
Late medieval "rekishi monogatari" and historical works.
The work "Masukagami" ("The Clear Mirror"), a historical tale of the kind discussed above, was created in the Nanbokuchō period. It was the last of the "mirrors" (鏡物 "kagami-mono") of Japanese history, and portrays the history, primarily of the imperial family, of the period between the emperors Go-Toba and Go-Daigo. Ichiko writes that it is a nostalgic work that emphasizes continuity from the past, and is lacking in new flavour, but that among the "mirrors" the quality of its Japanese prose is second only to the "Ōkagami".
Other works, such as the "", straddle the border between the courtly "mirrors" and the "gunki monogatari"; the most noteworthy work of this period, though, is Kitabatake Chikafusa's "Jinnō Shōtōki", which describes the succession of the emperors beginning in the Age of the Gods. Similarly to the "Gukanshō", it includes not only a dry narration of historical events but a degree of interpretation on the part of its author, with the primary motive being to demonstrate how the "correct" succession has followed down to the present day. Ichiko notes the grave and solemn language and tensity of the content of this work of historical scholarship, which was written during a time of constant warfare.
Late medieval "gunki monogatari".
The most outstanding tale of military conflict of this period is the "Taiheiki", a massive work noted not only for its value as a historical chronicle of the conflict between the Northern and Southern courts but for its literary quality. It is written in a highly Sinicized "wakan konkō-bun", and lacks the lyricism of "The Tale of the Heike", being apparently meant more as a work to be read than sung to an audience. It is infused with a sense of Confucian ethics and laments the last days, and its criticism of the rulers gives it a new flair. Ichiko calls it second only to the "Heike" as a masterpiece of the "gunki monogatari" genre. The work's title, meaning "Record of Great Peace", has been interpreted variously as satire or irony, referring to the "great pacification" that its heroes attempt to implement, and expressing a sincere hope that, following the end of the violent events it describes, peace would finally return to Japan.
Peace did not return, however, and, carrying over into the Muromachi period, war continued almost without stop. Tales of martial escapades in this period include the ', the ' and the "Yūki Senjō Monogatari" (結城戦場物語). Ichiko notes that while each of these works have unique characteristics, they tend to follow a formula, recounting the (mostly small-scale) real-world skirmishes that inspired them in a "blasé" fashion and lacking the masterful quality of the "Heike" or "Taiheiki". The "Tenshōki" (天正記), a collective name for the works , records the exploits of Toyotomi Hideyoshi. It and other works of this period, which Ichiko calls "quasi-"gunki monogotari"" (準軍記物語), portray not large-scale conflicts with multiple heroes, but function more as biographical works of a single general. This offshoot genre includes tales such as the "Soga Monogatari", which recounts the conflict of the Soga brothers, and the "Gikeiki", which is focused on the life of the hero Minamoto no Yoshitsune. Ichiko notes that this kind of work broke the "deadlock" in the military tales and (particularly in the case of the "Gikeiki") had a tremendous influence on the literature of later times.
Late medieval "setsuwa" literature.
"Setsuwa" anthologies were apparently not as popular in the late medieval period as they had been before, with writers actually favouring the creation of standalone "setsuwa" works. In the Nanbokuchō period, there was the "", a collection of "uta monogatari"-type "setsuwa" about poets tied to the Southern Court, but more noteworthy in Ichiko's view is the
's "Shintō-shū", believed to be the origin of the "", a genre of popular literature expounding Buddhist principles. The "Shintō-shū" contains 50 stories, mostly "honji suijaku"-based works describing the origins of the gods of Shintō. There is a focus in the work on the Kantō region, and on divinities with the title "myōjin", and it contains several "setsuwa"-type works, such as "The Tale of the Kumano Incarnation" (熊野権現事 "Kumano-gongen no koto") and "The Tale of the Mishima Grand Divinity" (三島大明神事 "Mishima-daimyōjin no koto") in the vein of "setsuwa-jōruri" and "otogi-zōshi".
Going into the Muromachi period, works such as the "Sangoku Denki" (三国伝記) and Gentō (玄棟) and Ichijō Kaneyoshi's ' are examples of "setsuwa"-type literature. A variant on the "setsuwa" anthology that developed in this period is represented by such works as "Shiteki Mondō" (塵滴問答) and ', which take the form of dialogues that recount the origins of things. Along with the "", an encyclopedic work compiled around this time, these stories probably appealed to a desire for knowledge on the part of their readers. Furthermore, more and more "engi" started being composed in this period, with new "emakimono" flourishing in a manner beyond that of the Kamakura and Nanbokuchō periods. Ichiko contends that these "engi" must be considered a special category of "setsuwa".
Toward the end of the medieval period, Arakida Moritake compiled his "Moritake Zuihitsu" (守武随筆). The latter half of this work, titled "Accounts I Have Heard in an Uncaring World" (心ならざる世中の聞書 "Kokoro narazaru yononaka no bunsho"), collects some 23 short stories. This work is noted as a forerunner to the literature of the early modern period.
Late medieval diaries, travel literature and essays.
The only surviving diary by a court woman in this period was the "Takemuki-ga-Ki" (竹むきが記), written by Sukena's daughter (日野資名女 "Hino Sukena no musume") during the Nanbokuchō period. A number of courtiers' Chinese diaries survive from this period, including the ' by , the ' by , and the "" by . The "Sōchō Shuki" (宗長手記), written by the "renga" master , is considered by Ichiko to be the only "kana" diary of this period to have literary merit.
Saka Jūbutsu's (坂十仏) work "Ise Daijingū Sankeiki" (伊勢太神宮参詣記), an account of a 1342 visit to the Ise Grand Shrine, is one example of a genre of travel literature describing pilgrimages. Other such works include the travel diaries of , a monk-poet who accompanied the shogun on a visit to Mount Fuji, Sōkyū's "Miyako no Tsuto" (都のつと), and 's "Kaikoku Zakki" (廻国雑記).
 A great many travel diaries by "renga" masters who travelled the country during this time of war, from "Tsukushi no Michi no Ki" (筑紫道) by Sōgi onward, also survive. Some warriors of the armies sweeping the country toward the end of the medieval period also left travel journals, including those of Hosokawa Yūsai and .
Not many "zuihitsu" survive from this period, but the works of poetic theory that were written by the "waka" poets and "renga" masters include some that could be classified as essays. The works of , including "Sasamegoto" (ささめごと), "Hitorigoto" (ひとりごと) and "Oi no Kurigoto" (老のくりごと) are examples of such literary essays, and are noted for their deep grasp of the aesthetic principles of "yūgen", "en", "hie", "sabi", and so on.
"Noh", "kyōgen" and "kōwakamai".
Drama is a major facet of Japanese literature in the medieval period. From the Heian period on, entertainments such as ', "dengaku" and "sarugaku" had been popular among the common people, while temples hosted music and dance rituals, namely ' and "ennen". In the 14th and 15th centuries, Kan'ami and his son Zeami, artists in the Yamato sarugaku, tradition created "noh" (also called "nōgaku"), which drew on and superseded these forerunner genres. These men were able to accomplish this task not just because of their own skill and effort, but also the tremendous favour shown to the burgeoning art form by the Ashikaga shoguns. Kan'ami and Zeami—especially the latter—were great actors and playwrights, and pumped out "noh" libretti (called "yōkyoku") one after the next.
Zeami also composed more than 20 works of "noh" theory, including ', ' and "". Ichiko calls these excellent works of aesthetic and dramatic theory, which drew directly on Zeami's experience and personal genius. Zeami's son-in-law Konparu Zenchiku inherited these writings, but his own works such as "Rokurin Ichiro no Ki" (六輪一露之記) show the influence of not only Zeami but of "waka" poetic theory and Zen. Later "noh" theorists like Kanze Kojirō Nobumitsu continued to develop on the ideas of Zeami and Zenchiku, and under the auspices of the warrior class, the nobility, and various temples and shrines the "noh" theatre continued to grow and expand its audience into the Edo period.
Closely related to "noh", and performed alongside it, was "kyōgen" (also called "noh-kyōgen"). "Kyōgen" was likely a development of "sarugaku", but placed more emphasis on dialogue, and was humorous and often improvised. At some time around the Nanbokuchō period this genre split off from mainstream "noh", and it became customary for a "kyōgen" performance to be put on between two "noh" plays. The language of "kyōgen" became solidified to a certain extent by around the end of the Muromachi period (mid-16th century). According to Ichiko, while "noh" consists of song, dance, and instrumentals, is more "classical" and "symbolic", and is based on the ideal of "yūgen", "kyōgen" relies more on spoken dialogue and movement, is more "contemporary" and "realistic", and emphasizes satire and humour. Its language is more vernacular and its plots more comedic.
"Kōwakamai" developed somewhat later than noh. According to tradition, the form was established by Momoi Naoaki (桃井直詮), a Nanbokuchō warrior's son whose was Kōwakamaru (幸若丸). "Kōwakamai" were performed by low-class entertainers in the grounds of temples and shrines, as musical adaptations of the medieval war tales, with their dances being straightforward and simple. 51 libretti are extant, including "heiji-mono" (平治物, works based on the "Heiji Monogatari"), "heike-mono" (平家物, works based on "The Tale of the Heike"), "hōgan-mono" (判官物, works about the tragic hero Minamoto no Yoshitsune), and "soga-mono" (曽我物, works based on the "Soga Monogatari"). Such performances were apparently well-loved by members of the warrior class during the chaotic period of the late 15th and 16th centuries, but went into decline in the Edo period.
Folk songs.
While ', as well as "enkyoku" (宴曲, or "sōga"/"haya-uta" 早歌) and "wasan" (Buddhist hymns), were popular in the early medieval period, the later medieval period was dominated by "sōga" and the newly emerging "ko-uta" (小歌). The representative collection of "ko-uta" is the 16th-century ', which includes a selection of "sōga", songs to be intoned and "kōtai" (小謡) songs from "dengaku" and "sarugaku" plays, arranged by genre, and more than a few of its entries sing of the joys and sorrows of the common people of that time. The "Sōan Ko-uta Shū" (宗安小歌集), compiled at the end of the Muromachi period, and the "Ryūta Ko-uta Shū" (隆達小歌集), compiled in the Azuchi–Momoyama period or at the very beginning of the Edo period, also collect "ko-uta" from this period. The "Taue-zōshi" (田植草紙) records the farming songs sung by rice farmers during the religious rituals performed when planting their rice paddies.
"Kirishitan" literature.
For almost a century after the arrival of Francis Xavier in Kagoshima in Tenbun 18 (1549), Jesuit missionaries actively sought converts among the Japanese, and the literature these missionaries and Japanese Christian communities produced is known as "Kirishitan Nanban" literature (キリシタン南蛮文学 "kirishitan-nanban bungaku"). This includes both translations of European literature and Christian religious literature produced in Japan. The Amakusa edition of "The Tale of the Heike" (天草本平家物語 "Amakusa-bon Heike Monogatari"), which translated the work into the vernacular Japanese of the sixteenth century and represented it entirely in romanized Japanese, was printed in Bunroku 1 (1592), and the following year saw the printing of the "Isoho Monogatari" (伊曾保物語), a translation into vernacular Japanese of Aesop's Fables that was similarly printed entirely in romanized Japanese. "Isoho Monogatari", because it was seen as a secular collection of moral fables, managed to survive the anti-Christian proscriptions of Tokugawa period, continuing to be printed in Japan until at least 1659, with several handwritten copies also surviving.
The Jesuits also published linguistic works such as the Portuguese-Japanese dictionary "Vocabulário da Língua do Japão" and João Rodrigues's "Arte da Lingoa de Iapam", which were originally produced to assist in proselytizing activities, but have become important resources for Japanese historical linguistics. Other works included "Dochirina Kirishitan", a Japanese edition of "Doctrina Christiana" that has been noted for its simple, clear and direct use of the Japanese vernacular.
Ichiko notes that these works, which were all produced in the Azuchi–Momoyama and very early Edo periods, did not have a significant influence on medieval Japanese literature, but are nonetheless an important part of the history of Japanese thought at the end of the .
