• What to do in an earthquake in Japan: the first 10 minutes, for visitors
  While it shakes, right after, and the hours after — the official guidance, condensed. Then the same guidance by place: hotel room, shop, theater, underground mall, elevator, train, street, coast.
• Tsunami warning in Japan: when to move, and when you can go back
  Six real situations from the app's deck — long shaking on the coast, a warning without any shaking, two hours on the hill — with the official answer and its source.
• Your travel SIM can't call 119: how to reach help in Japan
  Most travel SIMs and eSIMs are data-only, so the emergency numbers will not connect. Here is what works instead — and what to say when you get through.
• The Japanese on the wall after a disaster: 39 words, decoded
  断水, 炊き出し, 運転見合わせ — the words on walls and screens, decoded.
• 171 and web171: leaving word when calls won't connect in Japan
  After a big earthquake, calls fail because everyone calls at once. Text gets through; so does the 171 message board. Four questions from the deck explain when it runs and how to use it.
• How to read Japan's evacuation signs: the ○/× marks and the green pictograms
  The signs are everywhere; most visitors walk past them. Four questions from the deck, with the official sources.
