Mizuki was born Shigeru Mura (武良 茂 Mura Shigeru) in the city of Osaka, the second of three sons.
He was raised in the coastal city of Sakaiminato 境港, where he spent much of his childhood as a 'scrapper': picking fights and participating in childish warfare with the neighbouring children.
He displayed from an early age a particular talent for art.
During his time in elementary school, Mizuki's teachers were so impressed by his skills with a pencil that they organised an exhibition of his work, and he later went on to be featured in the Mainichi newspaper as something of an artistic prodigy.
In addition to this penchant for the artistic, Mizuki had an interest in the supernatural - something that was fueled by listening to ghost stories told by a local woman named Fusa Kageyama, but whom the young Mizuki nicknamed "Nononba".

However, in 1942, he was drafted into the Imperial Japanese Army and sent to New Britain Island in Papua New Guinea.
His wartime experiences affected him greatly, as he contracted malaria, watched friends die from battle wounds and disease, and dealt with other horrors of war.
Finally, in an Allied air raid, he was caught in an explosion and lost his dominant (left) arm.
Regarding this life-changing event, a Nov. 30, 2015 NHK announcement of his death showed excerpts of a video interview with him at age 80, in which he said that as the only survivor of his unit, he was 'ordered to die' — a prospect he considered ridiculous.
The result of Mizuki's wartime experience was a concurrent sense of pacifism and goodwill.
In the same interview, he explained that his Yōkai characters can be seen only in times of peace, not war, and that he purposely created these supernatural creatures to be of no specific ethnicity or nationality as a hint of the potential for humanity.
While in a Japanese field hospital on Rabaul, he was befriended by the local Tolai tribespeople, who offered him land, a home, and citizenship via marriage to a Tolai woman.
Mizuki acknowledged that he considered remaining behind, but was shamed by a military doctor into returning home to Japan first for medical treatment to his arm and to face his parents, which he did reluctantly.

Upon arriving home, Mizuki had initially planned to return to New Guinea; however, the occupation of Japan changed that.
His injuries did little to help, nor did the fact that his older brother, an artillery officer, was convicted as a war criminal for having prisoners of war executed.
After his return to Japan he worked at a variety of jobs including as a fish salesman and kamishibai artist.

In 1957, Mizuki released his debut work, Rocketman.
He published numerous works afterwards, both dealing with the military and with yōkai.
He has also written many books on both subjects, including an autobiography about his time on New Britain Island and a manga biography of Adolf Hitler in 1971.
This book was published in English in 2015 by Drawn & Quarterly.

Mizuki began a rental manga adaptation of the kamishibai Hakaba Kitarō (墓場鬼太郎, lit. "
Kitarō of the Graveyard") in 1960.
In 1965, it was renamed Kappa no Sanpei and began serialization in Weekly Shōnen Magazine, before being renamed again to GeGeGe no Kitarō in 1967.

In 1972 he publishes the gekiga graphic novel Nonnonba about his grandmother.

In 1991, he released a short work titled War and Japan (Sensō to Nippon) published in The Sixth Grader, a popular edutainment magazine for young people, detailing the atrocities committed by the Japanese Army during their rampage in China and Korea and is narrated by Nezumi Otoko.
The work serves as a powerful counterpoint to revisionist manga like the works of Yoshinori Kobayashi and by extension a way for Mizuki to express his anger at those responsible for all of Japan's victims.
From 1989 till 1998 he works on the series Showa: A History of Japan following the same approach and describing the Showa history combined with personal anecdotes.
In these books Nezumi Otoko is also the narrator.

When not working in either field, he painted a number of subjects, though these works are no
