Prefecture Survival is a watch-and-cheer battle royale: the shapes of all 47 Japanese prefectures bounce around inside a ring, and any prefecture that slips through the rotating gap is out. The last one standing wins. HOW IT WORKS 1. Tap Start and all 47 prefectures start bouncing after a 3-2-1 countdown 2. Part of the white ring is open. The gap rotates and slowly widens 3. Any prefecture that flies out is eliminated, and the elimination order is listed live at the top 4. The last prefecture standing wins. See the podium and the full ranking A game takes about two minutes, and the motion is random, so every result is different. Cheer for your home prefecture with friends and family. FEATURES - Real shapes: every prefecture outline comes from map data, color-coded by region - Region mode: play with only Kanto, only Kyushu & Okinawa, or any combination - All-time leaderboard: wins and podium finishes are recorded - Share results: winner, 2nd and 3rd place as text to social apps or messages - Satisfying sound effects: bumps, eliminations and a victory fanfare (can be turned off) - Settings: speed (4 levels), gap size, rotation speed, name labels, haptics SAFE AND SIMPLE - Free, no account, no internet connection needed - No ads, no in-app purchases - No personal data is collected. Stats stay on your device Results are a random simulation and do not rank real prefectures. Prefecture shapes are derived from Global Map Japan (Geospatial Information Authority of Japan).
