Blood for Blood (1971)

The Akiba and Shimura crime families run the streets of “K City”. With the construction of new buildings and new factories underway, the city has sprouted into a boomtown and business is good. Two of the most infamous mobs of Tokyo want a piece of the pie. As out-of-town yakuza flood the city overnight, the crime boss of the Akiba family, Tezuka (Joe Shishido), is released from prison after a five year sentence. He does not like the "change" he sees.
