Earlier this month two gunmen opened fire at Yoshihiro Oyadomari, the 64-year-old boss of the Furukawa-gumi, and a 61-year-old fellow gang member in front of a FamilyMart convenience store.
Oyadomari was struck in the left hand. The other gangster was shot in the buttocks. Neither victim is in a life-threatening condition, police said previously. Takuya Fujimura, a 52-year-old member of Tsukasa Kogyo, an affiliate gang of the Yamaguchi-gumi, turned himself in two days later.
The shooting is just the latest incident involving the Yamaguchi-gumi and Kobe Yamaguchi-gumi. The gangs have been engaged in a dispute since the Kobe Yamaguchi formed as a rival to the Yamaguchi-gumi in 2015.
