Yakuza Graveyard

A police investigator, born in Manchukuo, cracks down on yakuza business but his rough methods often get him in trouble with his superiors and he is transferred to a new beat in Osaka. He becomes embroiled in a turf war between the Nishida and Yamashiro families, but after being offered money by the Nishidas to take their side, he refuses and instead pressures young yakuza members into helping him arrest other criminals. As the situation escalates, Kuroiwa's own life is threatened, including his relationship with Keiko, the half-Korean wife of underboss Matsunaga, who tries to convince him to betray her husband but ultimately sides with Kuroiwa as he becomes embroiled in a violent and deadly cat-and-mouse game.
