In The Blind Swordsman: Zatoichi, we can see towards the end how the titular character deals with the local yakuza gang. When he manages to kill most of the soldiers, the leader and his henchman run away towards the beach, where the only person capable of killing Zatoichi awaits.

In the next scene, we can see two fishermen... and the body of the yakuza boss:
