A detective is charged with investigating a bank corruption scandal.

The blind masseuse is targeted by the leader of a powerful yakuza group while also fending off a jealous husband bent on revenge. Zatoichi tours Edo's underground via a rousing onsen fight scene, gambling houses and the gender-bending character of Umeji, before a final, flame-filled conflagration.

Older, wiser but still a wandering loner, the blind, peace-loving masseur Ichi seeks a peaceful life in a rural village. When he's caught in the middle of a power struggle between two rival Yakuza clans, his reputation as a deadly defender of the innocent is put to the ultimate test in a series of sword-slashing showdowns.
