Jishin Sensei

Visiting Japan? Curious about it? Earthquakes are part of life here — and knowing what to do is easier than you think.

Jishin Sensei ("Earthquake Teacher") turns Japan's earthquake wisdom into a fun daily habit. Every day, Namazu Sensei — the legendary catfish of Japanese earthquake folklore — asks you one real-life scenario question: What would you do?

Start before you fly: one question a day builds real instincts. And if the ground ever shakes, every emergency number and guide is already on your phone — working fully offline.

DAILY QUIZ • One scenario question every day — hotels, trains, onsen, coastlines • Instant explanations with official sources (JMA, JNTO, and more) • Build your streak and share your results, Wordle-style • Answer at your own pace — no time pressure (the clock only runs in the optional Challenge mode)

EMERGENCY TAB — WORKS OFFLINE • Japan's emergency numbers: 110, 119, 118, #7119 • Disaster Emergency Message Dial (171) guide • 24/7 multilingual Japan Visitor Hotline • Embassy tips — all guidance stored in the app, readable with no connection

LEARN THE REAL THING • 68+ scenario questions across five categories: Basics, Action, Communication, Information, Survival • Every answer backed by official English sources from Japanese public authorities • Official links to hear the real earthquake alert tone before you ever need it • Fun facts along the way: why IS the teacher a catfish?

SUPPORTER (OPTIONAL) The daily quiz and the Emergency tab are free forever. Supporters unlock the full question archive and keep new questions coming — you pay for comfort, never for survival.

Built for travelers, exchange students, and Japan fans everywhere — in English, Japanese and Korean. Stay curious, stay safe.
