The samurai Sakawa Kojūrō is on the road to Edo with his two servants Genta and Genpachi.

On the road, they encounter many different people: a traveling singer with her child, a father taking his daughter Otane to be sold into prostitution, a pilgrim, a policeman searching for a notorious thief, and Tōzaburō, the suspicious man the officer has his eyes on.

Genpachi, the spear carrier, is also followed by an orphaned boy named Jirō who wants to be a samurai.

Authorities do not charge him with a crime, so he heads home carrying the ashes of Kojūrō and Genta.

Bloody Spear at Mount Fuji was screened in the Museum of Modern Art as part of a retrospective on Tomu Uchida in 2016.
