About this game
Run a sumo stable! Recruit rookies, drill their stats, cook chanko nabe, and steer them through six grand tournaments a year. In this sumo sim, you climb the banzuke from Jonokuchi to Yokozuna while juggling injuries, rivalries, and an empty bank account. Work hard to make your heya legendary!
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

First Major Update to Uchi No Heya!
v1.1 - The SumoDB/Staff Update THE SUMODB (Steam / desktop) The RECORDS room is now extremely meaningful. A full career database tracks every real bout in the game world. Wins and losses by kimarite, career streaks, head-to-heads, kinboshi, injuries, and full basho-by-basho history for every rikishi, including retired legends (a career archive preserves notable AI careers forever). - DATABASE tab in RECORDS: a searchable index of every known rikishi with division, status, and sort filters - Full profiles: wins-by-style spider charts, winning and lost-by kimarite bars, rank progression with division bands, division records, streaks, injury history, the complete basho log, and a recent-form strip that reads newest-first - Record boards: 14 boards such as Career Wins, Championships, Special Prizes, Gold Stars, Kimarite Variety, and more - All Heyas: every stable in career's world in one expandable table - members, combined career record, current injuries, and each heya's best rikishi - Rivals on the card: the RIKISHI page lists each man's rivals. who they are, the rank the feud began at and how long it's gone on, head-to-head score etc. clicking one opens the full comparison to show careers side by side with overlaid spider charts and their rivalry timeline - Database is reachable from important places: a DATABASE button under the portrait on every RECORDS rikishi card, DATABASE and COMPARE plaques on the banzuke fighter card and Matchup Details, and every row of the day's SCHEDULE opening the head-to-head of that bout's two rikishi - Where it really earns its keep is mid-basho: scout your opponent, see the moves he wins with and the ones he loses to, then aim your coach's INSTRUCT at the line that beats him and cook the chanko that focuses your man on the right styles - Jun-yusho (Makuuchi runner-up) is now credited and displayed; the AI world quietly earns sansho by the same standards you do THE BASHO ARCHIVE (all platforms) A new BASHO tab in RECOR...Read full article on Community Announcements (James West)Patch NotesOfficial
Banzuke/Logic updates
v1.0.7 is out (web + Steam) — banzuke and scheduling release:- The banzuke never publishes empty sanyaku ranks again. the committee now always fills both Sekiwake and Komusubi slots the way real Ozumo does, reaching into the upper Maegashira when it must. - Top-heavy eras now schedule like real sumo (thanks Spiffy for the forensic report): with 3 Yokozuna and 5 Ozeki around, Y/O clashes now start early enough for everyone to actually face each other and a yusho co-leader will not dodge the other co-leader on senshuraku. Your 15-0 means something now. This applies to the AI too- Off-season can't be skipped by quitting after a week-0 workout, the chanko feeding menu scrolls when you've stockpiled bowls, and imported saves now receive all the achievements they'd already earned — load your web import on Steam and years of progress pop at once. Divine bowls also now count for the Excellent chanko achievement.- macOS: fullscreen works properly now.Read full article on Community Announcements (James West)Patch NotesOfficial
V 1.0.3 - Launch hotfixes
Small hotfixes - Fixed low FPS on the Fall and Spring off-season backgrounds (Steam/desktop) — scenery now renders as a single baked image; leaves, petals, and snow still animate. - Fixed rapid clicks during a bout replaying the finishing throw and launching a rikishi off-screen. - Fixed the day advancing underneath an open schedule overlay when using a controller — overlays now properly capture focus, and advancing the day closes any open overlay. - Fixed Hardcore (Heya) scouting showing the base price while charging the 1.3× hardcore price — the label now always shows what you'll actually pay. (The higher cost itself is intended hardcore behavior.)Read full article on Community Announcements (James West)Patch NotesOfficial
Steam Deck Hotfix and other small bugs
This update should get steam decks using the right depot! Also fixes: NaN being displayed during bouts where a rikishi's stat is over 100 Events that are too expensive being offered too early "Top Division" achievement description corrected to Makuuchi This also brings the Steam version up to date with other patches that were live on the web version for some balance changes and matchmaking fixes.Read full article on Community Announcements (James West)
