Mukoubuchi 4: High Stakes Mahjong Legend – Mahjong Parlor Killer

A pair of Kansai-region underground mahjong hustlers begin storming Tokyo’s local mahjong parlors, scamming unsuspecting players with clever cheating techniques. One of their victims, Yasunaga Ban (played by pro-wrestler Takada Nobuhiko), is the owner of a mahjong parlor. Seeking revenge, he challenges them to a high-stakes match—but loses. As he's about to give up, a mysterious and feared man known only as “The Outsider” (Mukoubuchi), KAI (played by Yoshihiko Hakamada), enters the scene. Kai immediately sees through the Kansai duo's tricks and defeats them without mercy. However, a larger threat looms when a powerful figure from Kansai, Katsuta, comes to Tokyo, escalating the conflict to a new level of tension.

Directed by Shūji Kataoka, Mukoubuchi 4: High Stakes Mahjong Legend – Mahjong Parlor Killer leans on a strong ensemble — Yoshihiko Hakamada, Eisaku Shindo, Nobuhiko Takada — to carry a story that balances spectacle with character.

The film landed with audiences for its craft and performances, and remains one of the most talked-about crime titles of 2025.
