Answers to the common questions, and how to reach us.

My purchase didn't unlock / I reinstalled the app

Open Settings → Restore purchases inside the app. The unlock is tied to your App Store account, so it can always be restored on any device signed in to the same account — no extra charge.

Where are my photos stored?

Only on your device. Japan 100 has no accounts and no servers, so your photos and progress are never uploaded anywhere (see the Privacy Policy). That also means: deleting the app deletes your board — there is no cloud backup to restore it from, so think twice before uninstalling mid-trip.

Can I get a refund?

Purchases are processed by Apple, so refunds go through them: reportaproblem.apple.com. We cannot issue refunds ourselves.

A quest seems wrong or outdated

Etiquette changes, shops close, festivals move. If a quest or its tip no longer matches reality, we genuinely want to know — email us and we'll fix it in an update.
