Sachio Umemoto

Description
Sachio Umemoto was a Japanese manga artist active in the late 1960s through the 1970s, known for his contributions to the sports and action genres. He was born on February 6, 1943, in Tosa-Shimizu, Kochi Prefecture, and passed away on September 6, 1993. Umemoto made his professional debut with a rental manga, or kashihon, titled I Have My Dream, published by Hinomaru Bunko. Following his debut, he gained experience working as an assistant to established manga artists Masaaki Sato and Tetsuya Chiba, the latter being the renowned creator of Ashita no Joe.

Umemoto achieved his first major breakthrough with the series Kujira Daigo, which was serialized in the very first issue of Weekly Shōnen Jump in 1968. However, after a period of working under an exclusive contract that he reportedly disliked, he left the publication and began working for Shōnen King in 1970. It was there that he created his most famous work, Apache Yakyuugun, also known as Apache Baseball Team, with the story credited to Kobako Hanato. The manga became a significant hit and was adapted into a television anime series that aired 26 episodes from October 1971 to March 1972. In the anime adaptation, Umemoto is credited as the original creator alongside Kobako Hanato, who provided the story.

His career was prolific, with his work appearing across Japan's major weekly and monthly manga magazines of the era, including Weekly Shōnen King, Weekly Shōnen Champion, Weekly Shōnen Jump, and Weekly Shōnen Sunday. Other notable manga series he created include Little Dan-chan, Flying Wings, The Big Whale, Sea Boy, and Cane. He also contributed to the industry as a writer, penning the story for a series titled Devil Swordsman.

Throughout his career, Umemoto frequently returned to sports-themed narratives, particularly baseball, as seen in works like Apache Yakyuugun, Ryūsei Kyūdan (Meteor Baseball Team), and Ritoru no Dan-chan (Little Dan-chan). He also worked in action-adventure genres with titles such as Chōsensha Kēn (Challenger Kane) and the school-bande-focused Kaze no Banchō, which was written by Tetsu Kariya. Later in his career, he explored more unconventional sports settings, such as bowling in Shinku no Bōrā (Deep Crimson Bowler).
