Hiroshi Kaizuka
Hiroshi Kaizuka (November 7, 1938 - September 2023) was a Japanese manga artist from Chiba Prefecture. He debuted in rental-book manga in 1957, began Kurikuri Toshu in Omoshiro Book in 1958, and earned a reputation as a hot-blooded shonen artist with sports and war-themed hits. When Shonen Jump launched in 1968 he supported the magazine's early days as one of its flagship artists, serializing Chichi no Tamashii from the inaugural issue; his Judo Sanka (story by Ikki Kajiwara) was adapted into a TV anime in 1974.
