What is Vagabond based on?
Every Vagabond cover says so, in both languages. Inoue's manga is a loose adaptation of Musashi, the epic novel Eiji Yoshikawa serialized in the Asahi Shimbun from 1935, which retells the life of Miyamoto Musashi (c. 1584 to 1645), the undefeated swordsman who wrote The Book of Five Rings. Yoshikawa's version, part history and part invention, became so popular that for most Japanese readers it simply is Musashi's story.
Inoue read it and wondered about the part the legend skips: the young man before the mastery, violent, frightened, and animal. That question is Vagabond. The novel gives the manga its route and its cast; the manga repays the debt by reimagining nearly everything it touches, which is the subject of the next page in this archive.
