"Shin Takarajima" (Japanese: 新宝島, pronounced [ɕintakaɾadʑima] ⓘ, "New Treasure Island") is a one-shot manga published by Ikuei Shuppan in 1947.
It is Tezuka's debut full-length work, and is considered to be the starting point of postwar Japanese manga.
A revision of the manga was made by Tezuka in 1984, as part of Kodansha's Osamu Tezuka Complete Manga Works series, featuring 250 redrawn pages compared to the original 190 pages, a slightly different plot, and a brand new ending that features a plot twist.
[1] Tezuka has a thing called the star system in which he would reuse the same characters in multiple different stories, inspired by Hollywood actors.
Many people who read the manga upon its release were inspired to become a cartoonist, this includes the Fujiko Fujio duo,[2] Shotaro Ishinomori,[3] Tetsuya Chiba,[4] Mikiya Mochizuki,[5] Mitsutoshi Furuya,[6] Kazuo Umezu,[7] Noboru Kawasaki,[8] Keiji Nakazawa,[9] and Yoshiharu Tsuge.
