is a Japanese manga artist known for his far-right political commentary manga Gà Âmanism Sengen. In particular, the three volumes On War (Sensà Âron) of this series made him famous in Japan, together selling more than 1.5 million volumes since first appearing in 1998.
A student of French literature from Fukuoka University, Kobayashi published his first manga, Tà Âdai Itchokusen, in 1976 in Weekly Shà Ânen Jump while still in school. Another of his early series, Obocchama-kun, a satire about a naughty rich boy in the heyday of Japan's bubble economy, won the 1989 Shogakukan Manga Award for children's manga.
Kobayashi was included on Aum Shinrikyo's assassination list after he began satirising the cult. An assassination attempt was made on him by the members of the cult in 1993.
Kobayashi is a denier of both the Nanjing Massacre and of the comfort women system during World War II.
