One of the best Japanese comics I’ve ever read is Vagabond. It’s a fantastic series about real life samurai master Musashi Miyamoto who was alive in the late 1500s.
The story details his life and his famous duels with other sword masters. Showing his path from delinquent youth to philosophical master. You can actually read the book of his strategies and thoughts that he wrote. It’s called “The Book of the Five Rings, and it’s still available today in many languages.
The comic itself is very exciting and full of action and very beautiful art. It’s drawn by Takehiko Inoue, who is a very famous manga author in Japan. I highly recommend this series to anyone who loves history or action. It’s also available in English at various bookstores.
