Maison Prison

Maison Prison, known in Japanese as ムショラン三ツ星, is an upcoming Japanese television series scheduled to premiere on May 23, 2026. The series centers on Ginbayashi Yoko, a chef formerly employed at a high-end Italian restaurant. When the restaurant's owner absconds with its earnings and the establishment closes, Yoko, a mother of two, accepts a nutritionist role at a local men's prison. Her responsibilities initially focus on planning monthly menus, but at the warden's encouragement she expands her ambitions toward using food as a vehicle for inmate rehabilitation. The series frames its central tension around whether individuals are capable of genuine change, and whether Yoko herself can redefine her professional purpose within an institution as unlikely as a prison kitchen. The title is a play on the Michelin star rating system, with the series framing Yoko's goal as earning a figurative "three-star" distinction for prison cuisine.
