Yama–Ichi War

The Yama–Ichi Feud (山一抗争, Yama-Ichi Kōsō) was a yakuza conflict mainly fought in the Kansai region of Japan from 1985 to 1989, between the Yamaguchi-gumi and the Ichiwa-kai gangs. Kazuo Taoka was the third boss of the Kobe-based Yamaguchi-gumi, who made the family into by far the biggest yakuza family in Japan. When he died of natural causes in 1981, then wakagashira (underboss) Kenichi Yamamoto was in prison and the other top lieutenants decided to wait for his release. However, in early 1982, Yamamoto suddenly died of liver failure. After his death, the top lieutenants could not immediately elect a boss, and they temporarily chose Hiroshi Yamamoto as acting boss and Masahisa Takenaka as wakagashira.
