Yakuza 1/yakuza kiwami
At the start of the first Yakuza game and its remake Yakuza Kiwami Sohei still serves as the patriach of the Dojima family, however it is made clear that Kazama has more or less all authority over it. Dojima is stated by Akira Nishikiyama to boast a lot about his "glory days" (before Kazama took control of the family).

Sohei abducts Yumi, a childhood friend of Kiryu and Nishiki and attempts to force himself on her. Nishiki enters the room and shoots Dojima several times before he can. Sohei bleeds out and dies.
