## What is Jishin Sensei?

"What do you do when the ground shakes?" Learn it one question a day — and carry the rest with you: communication cards to set up before you land, and an emergency guide that opens with no signal. In English, Japanese, Korean, and Simplified and Traditional Chinese. All of it free. For people visiting Japan, and people living here.

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

And if the ground ever shakes for real, the emergency numbers, the what-to-do-where guide and the cards you show people are already on your phone, and they work offline.

PREPARE TAB — SET UP BEFORE YOU LAND
• Communication cards: "Is there a tsunami risk here?", "There are things I can't eat" — the lines you are likely to need, in large Japanese, read aloud at one tap. Tap what happened to build the sentence, and the other person answers on the card: they tap a tile, type, or draw. In the Japanese UI they turn into cards for helping a foreign visitor, in English, Korean or Chinese; food and blood type become boards to point at
• My health card: allergies, diet, blood type and medication, shown in Japanese when it matters. Stored only on your phone (iOS Keychain). Save it as an image for your lock screen
• My trip card: where you stay, your flight home, who you travel with, who to call — set once, shown in Japanese, and filled into the cards for you. Saves straight to Photos
• Signs and notices: a mini-dictionary of the Japanese on walls and screens — 断水, 炊き出し, 運転見合わせ, 緊急避難場所. Paste text from a photo or type in English to search; it reads aloud too
• Destinations: Tokyo, Osaka, Kyoto, Hokkaido, Okinawa, Fukuoka, Nagoya, Hiroshima, Kanazawa — each area's official disaster app where there is one, multilingual page and tsunami note
• Install before you land: Safety tips, the official app supervised by the Japan Tourism Agency

EMERGENCY TAB — WORKS OFFLINE
• "Feeling an earthquake?" — what to do while it shakes, right after, and in the hours that follow
• "Where are you right now?" — the same guidance sorted by place: hotel, elevator, underground, coast
• Japan's emergency numbers (110, 119, 118), the #7119 medical advice line with numbers you can actually dial, the Disaster Emergency Message Dial (171) guide, and the 24/7 multilingual Japan Visitor Hotline
• One tap to your health card, trip card, sign dictionary and communication cards

DAILY QUIZ
• One scenario question every day — hotels, trains, onsen, coastlines
• Instant explanations with official sources (JMA, JNTO, and more)
• Streaks and stats; share today's result in one tap
• Answer at your own pace — no time pressure (the clock only runs in the optional Challenge mode)
• The whole deck is open: review any of the 68 questions, run Study Mode (or just the ones you missed), or take the 10-question Challenge

68 QUESTIONS, WITH SOURCES
• 68 scenario questions across five categories: Basics, Action, Communication, Information, Survival
• Every answer links to its source — mostly Japanese public agencies
• A link to hear the real phone alert tone, on a mobile carrier's page, before you ever need it
• Fun facts along the way: why IS the teacher a catfish?
• Earn category badges — and a shareable Certificate of Completion from Namazu Sensei

FREE — ALL OF IT
Every question, Study Mode, Challenge, the Prepare tab and the Emergency tab: free, for everyone. If the sensei has earned a snack, there is a tip jar in Settings.

Built for travelers, exchange students, people living in Japan, and Japan fans everywhere. Earthquake know-how — a charm for your trip, and for your days in Japan.

## Version history (last 5 releases)

### 1.0.12 — 2026-10-14

• Once earned, your Certificate and its share button also appear in Settings
• In light mode, gold text is now darker and easier to read

### 1.0.11 — 2026-10-13

• "Feeling an earthquake?": each line now matches the daily question behind it, with new lines for an underground mall and the upper floors of a tall building, and a button at the end to open the communication cards
• Emergency tab: the #7119 note now says #7119 doesn't cover all of Japan and that the Japan Visitor Hotline can also advise. On iPad, a note says the iPad may not be able to call these numbers
• My trip card: tap the new "I live in Japan" option, and the card and the "Please help me" card say you live in Japan instead of saying you are a visitor. You can also pick it right on the "Please help me" card
• My trip card: "Pick the date" now opens a calendar and saves only the day you choose, instead of saving today at once
• "Clear this card" empties your trip card or health card in one go
• My health card follows the Consumer Affairs Agency's allergen chart as of April 2026: cashew nuts join the nine always shown at the top, and you can now also choose pistachios and macadamia nuts
• My health card: "Save as image" now makes a picture the size of your screen, laid out to stay clear of the lock screen's clock and buttons. Items no longer break in the middle of a word
• Today: when the date changes, the screen moves on to the new day's question by itself. Coming back to the app reschedules your reminders, and time spent away no longer counts toward your answer time
• Your Certificate of Completion stays once earned, even after a later wrong answer

### 1.0.10 — 2026-09-24

• Now on iPad: the app sits in a centred column at a comfortable reading width, in either orientation
• Fixed on iOS 27: the Back button could stop responding after its first use

### 1.0.9 — 2026-09-21

• In Japanese, the cards you show a visitor now come with answer boards, so they can point back
• A new "ask" set: where they are staying, who to contact, what comes next
• Forty-five new pictures (107 in all): what an elevator does when a quake starts, the 66 tsunami forecast regions, the ward the embassies gathered in, the 4,360 stations behind the Shindo number
• The app's own 63 charts now also come in Korean and in Simplified and Traditional Chinese — the Japanese you will see on real signs and screens stays as it is
• Corrections to the text and pictures in all five languages

### 1.0.8 — 2026-09-17

• Sources rechecked: 17 questions now link to official pages that state the answer itself — from JMA, JNTO, the Japan Tourism Agency, the Government of Japan, the Tokyo Intercultural Portal and others
• Answers and explanations are reworded to say only what those sources say — covering why trains stay stopped after a quake, leaving a hotel by the stairs, pulling over while driving and why a tsunami can come even when you felt no shaking
• More source links open in your own language
