ShiroWalk is a collection-style walking game where your daily steps bring Japan's iconic castles to life — across 5 historic stages, from bare foundations to magnificent completion.
Why ShiroWalk
■ Zero ads. No gacha.
480 yen/month subscription. No ad interruptions, no random pulls.
Walk at your own pace, on your own terms.
■ 47 Castles × 5 Stages
From Hokkaido to Okinawa — all 47 prefectures.
Each castle evolves through 5 stages: S0 (empty lot) to S4 (completion).
Complete one castle to unlock the next. Watch your collection map turn gold.
■ 4 Legendary Phantom Castles (not for sale)
Earn special titles to unlock historically lost castles:

- 5,000,000 steps: Heian Imperial Palace
- 100 consecutive days: Hiraizumi Muryoukouin
These can never be purchased. Walking earns them.

How steps work
ShiroWalk reads your steps from Apple Health (read-only, never writes or sends data externally).
One castle requires roughly 100,000 steps. At 7,000 steps per day, that is about 2 weeks per castle.

Improvements to step tracking and the map view.
• Fixed an issue where your castle could appear stuck at the empty-lot stage when step access wasn't granted — your saved building progress now always displays correctly.
• Fixed the Japan map in the Encyclopedia not rendering. Completed prefectures now shine in gold.
• The price shown in Settings now matches your local App Store price.
• Minor display refinements.
