Disaster Apps and Multilingual Emergency Info for Foreigners in Japan

Quick answer (30 seconds): Before anything happens, install at least two free apps: Safety tips (Japan's official multilingual alert app, 15 languages, push warnings for earthquakes, tsunami and weather) and one shelter-finder such as Japan Shelter Guide. Phones on Japanese networks already receive J-Alert and Earthquake Early Warning automatically as a loud siren-like alarm, but those are mostly in Japanese, so a multilingual app is your translation layer. Learn one phrase pair now: hinan-basho (an immediate-safety evacuation site, like a park) versus hinanjo (an evacuation shelter where you can stay). In an earthquake: drop, cover, hold on. For a typhoon: prepare days ahead and follow your city's evacuation level.

Why a foreigner in Japan needs this

Japan gets earthquakes, typhoons, floods and the occasional tsunami, and the official warning chain is fast and serious. The catch for non-Japanese speakers is that the loudest, fastest alerts (the phone alarm, the TV takeover, the outdoor loudspeakers) are mostly in Japanese. The fix is simple: layer one or two multilingual apps on top of the alerts your phone already gets, and learn a few words so you understand what an alert is telling you to do.

This guide covers what to install, the alert systems running in the background, the all-important hinanjo vs hinan-basho distinction, and what to actually do in an earthquake or typhoon.
