Why ShiroWalk
■ Zero ads. No gacha.
480 yen/month subscription. No ad interruptions, no random pulls.

■ 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.

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.

Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
Redesigned share cards that put your steps front and center — plus an all-new completion ceremony.
• All-new completion ceremony: your castle rises in golden light, and you receive a commemorative "Goshuin" castle seal.
• Create and share a card at your castle's milestones (first growth, midway, and completion) showing how far your steps have taken it.
• A gentle share suggestion appears at those moments — you can simply dismiss it.
• Refreshed the card design so your step count and castle name stand out at a glance.
• The shared step count now correctly matches the castle you are currently building.
• Full support for Reduce Motion accessibility settings.
• Other minor display refinements.
We'll keep improving so you can grow your castle at your own pace.
