Buichi Terasawa (寺沢武一, born March 30, 1955-2023) is a Japanese manga artist.
Graduated from Asahikawa Higashi High School in Hokkaido in 1974. Originally, he wanted to go to medical school, but after high school, he decided to pursue his career in a cartoonist because he had no other job. In 1976, a manga he submitted to Tezuka Productions caught the attention of Osamu Tezuka, and he started studied under Tezuka. He moved to Tokyo and worked as a staff member of Tezuka Productions Manga Department. After working as an assistant to Osamu Tezuka, he made his debut in 1977 with "Cobra" in Weekly Shonen Jump (published by Shueisha). He quickly became a popular science fiction writer, and "Cobra" was developed into a theater animation and video game software.
His drawing style is strongly influenced by American comics. The color manuscripts, with their detailed backgrounds, have reached a level where they can be used as stand-alone pop art, regardless of whether they are comic book manuscripts or not, and are highly regarded all over the world.
A pioneer in the use of computer graphics for manga production, he began focusing on PC-based production in the early 1980s, and in 1992 published the world's first full CG manga, the digital comic "Take Takeru". His work has been highly acclaimed overseas, and his books have been translated and published in more than a dozen countries.
