Uchi No Heya! is a comprehensive sumo management simulator that puts you in control of your own stable. It runs through everything you would expect out of a good sumo simulator! All sumo divisions, all kimarite, and small details like special promotion/demotion logic for sekiwake/ozeki/yokozuna. In hardcore mode the difficulty is aimed more toward real world difficulty, with only the best of the best reaching the top!
Compared to the free web version of this sumo manager, the steam version includes 2 Hardcore modes, and an in-game sumo database of every rikishi, basho, and heya in your game! Use data to better coach your rikishi and track their road to yokozuna.
There will be a free update coming soon that adds an expansive post-game mode using your retired rikishi from any career mode as well!
Climb a ladder of over 600 rikishi across real-world divisions
Master all 82 Kimarite
Simulate basho, off-season events, and real banzukes with accurate sumo logic
Scout new rikishi, manage your facilities, and manage your Heya's upgrades.
Over 300 random events for the off-season, with more being suggested by the community all the time!
Employ rikishi as staff and chanko chefs for more management options
