■ Live in Showa-era Tokyo. Rise through mahjong.
A 2D pixel-art life simulation RPG set in a fictional postwar Japanese town.
Work, status, and relationships often hinge on mahjong battles.
Start at age 16, earn Jansen (in-run currency), climb citizen rank, and aim for mayor.
■ Mahjong as RPG combat
Two-player mahjong with unique rules and HP-based battles—not simple score chasing.
Level up, equip skills, manage flow gauge, riichi, calls, and fever tables.
■ Daily life loop
Explore the town by day, work and shop, fight at night.
Seasons, weather, newspapers, romance, jobs, bounties, tournaments, and rebirth cycles.
■ Free to play with optional ads
Core gameplay is free. Optional rewarded ads grant in-game currency.
Interstitial ads may appear when sleeping to the next morning (rate-limited).
In-app purchases are not available in v1.0.
■ Cloud World (optional)
Cloud save and ranking via the title screen.
Fiction only—not real-money gambling.

Koban shop unlocked (ad removal, home careers). Added cat hints, shanten display, a danger cue from the cat, opponent faces with expressions, and more personality in townspeople's lines.
