Kamui is a Japanese manga series written and illustrated by Sanpei Shirato. It was serialized in Seirindō's monthly gekiga magazine Garo between December 1964 and July 1971, with its chapters collected in 21 tankōbon volumes. Set in feudal Japan, it tells the story of Kamui, a low-born ninja who has fled his clan, which pursues him. It illustrates the true nature of the Edo period and the discrimination that existed within the feudal system. The series combines historical adventure with social commentary and themes of oppression and rebellion that reflect Shirato's Marxist convictions. By October 2021, the series had over 15 million copies in circulation.
