Making his debut in 1972, he first found success with the hardboiled detective manga series Doberman Deka (1975–1979) alongside illustrator Shinji Hiramatsu.
He is best-known for creating the post-apocalyptic martial arts series Fist of the North Star (1983–1988) with artist Tetsuo Hara, which is one of the best-selling manga in history with over 100 million copies in circulation.
Tuition is free, and students attend 20 lectures from professional writers, artists and editors throughout the year for a total of 100 hours.
[5] He made his manga writing debut in Weekly Shōnen Jump in 1972 with the one-shot Gorō-kun Tōjō,[6] illustrated by Yō Hasebe.
He was credited by the pen name Buronson, a nickname given to him by colleagues at Motomiya's studio after they all saw the film Adieu l'ami and felt he was similar to its actor Charles Bronson.
It was coined by rearranging the letters of his real name when written in English to "Syo Shimura", then writing it in Japanese and changing some characters.
Shortly after beginning Doberman Deka, Fumimura worked for Futabasha for the first and only time with Hakkyū Suikoden Hoero Ryū, drawn by Mitsuru Hiruta.
[9] When he also began the Self-Defense Force manga Phantom Burai in Shōnen Sunday Zōkan in 1978 with Kaoru Shintani, he was writing three series simultaneously for three different publishers.
[11] Buronson's greatest success, Fist of the North Star drawn by Tetsuo Hara, made its debut in Weekly Shōnen Jump in 1983.
[12] From 2001–2010 Hara created a seinen sequel in Weekly Comic Bunch, Fist of the Blue Sky, that Buronson supervised and gave advice on.
