Goseki Kojima was born on November 3, 1928. In 1950, Kojima moved to Tokyo, where the postwar devastation had given rise to special manga forms for audiences too poor to buy the new manga magazines. Kojima created art for kami-shibai, or "paper-play" narrators, who would use manga story sheets to present narrated street plays. Kojima moved on to creating works for the kashi-bon market, bookstores that rented out books, magazines, and manga to mostly low-income readers. He soon became highly popular among kashi-bon readers.
In 1967, Kojima broke into the magazine market with his series Dojinki. As the manga magazine market grew and diversified, he turned out a steady stream of popular series. In 1970, in collaboration with Kazuo Koike, Kojima began the work that would seal his reputation, Lone Wolf and Cub. Before long the story had become a gigantic hit, eventually spinning off a television series, and six motion pictures.
When Manga Japan magazine was launched in 1994, Kojima was asked to serve as consultant, and he helped train the next generation of manga artists. In his final years, Kojima turned to creating original graphic novels based on the movies of his favorite director, Akira Kurosawa. Kojima passed away on January 5, 2000 at the age of 71.
