Narushima Ryūhoku
Narushima Ryūhoku (成島柳北, 1837–1884) was a Japanese author and scholar born in Asakusa. His given name was Korehiro (惟弘). The Narushima family were okujusha (奥儒者), or Confucian tutors to the Tokugawa shōguns, who were also involved in editing the Tokugawa jikki (德川實紀) and other historical annals, including the Nochikagami (後鑑). Ryuhoku participated in these editing projects as a young man.
