About this game

Showa Mahjong Story RPG is a 2D pixel-art life simulation set in fictional post-war Tokyo.

Work, shopping, relationships—in this world, almost everything is settled through mahjong battles.

At age 16, with only an uncle to rely on, you begin a life supported by your skill at the table. Earn mahjong money, raise your citizen rank, and aim to become mayor.

Story

April 1, Showa 34—the story begins on this spring day.

Train at mahjong school, fight in parlors, find work and income. Build reputation, pass certification exams, and become a face of the town.

Seasons turn with rain, snow, and summer fireworks. Romance in your 20s, marriage or single life in your 30s—life milestones arrive alongside mahjong duels. Even beyond the path to mayor, a long life continues.
