About Japan Safe
About & Data Sources
Japan Safe is an independent project that puts earthquake, typhoon, and other disaster-related travel information in front of you in Korean, English, and Chinese. Here's where that information comes from and how often it's refreshed.
Who runs this
Japan Safe is run by the InfoEpic project. Any page with sponsored or affiliate content discloses that on the page itself. Real-time data (earthquakes, trains, typhoons) comes straight from official sources regardless of advertising.
Where the data comes from
Everything below is collected automatically — no manual editing.
Earthquakes
Official Japan Meteorological Agency (JMA) API. Intensity, magnitude, epicenter, and tsunami data all come from here.
Train status
Yahoo Japan Transit (transit.yahoo.co.jp). Real-time status for 8 major Shinkansen and city lines.
Typhoons
JMA typhoon tracking — path, category, and forecast impact areas.
Media coverage volume
Daily count of "Japan earthquake" articles from Google News RSS, compared against the maximum the feed can return in a day (100).
News video
YouTube Data API, restricted to verified broadcaster channels: NHK, ANN, TBS, Nippon TV, FNN, YTN, SBS.
Translation
Real-time items (like news headlines) are machine-translated via the MyMemory API. Blog articles are written natively in each language, not machine-translated.
Update frequency
The main dashboard (recovery index, earthquake alerts, train status, typhoon data) refreshes automatically every 10 minutes. If a source is temporarily unreachable, the page keeps showing the last successful value rather than going blank — which means it may occasionally lag behind the current moment. For actual evacuation decisions, always confirm with the official sources below.
How articles are written
Each article is based on official sources — JMA, local governments, established media — and facts (casualty figures, facility reopening dates, etc.) are checked before publishing. Articles covering information that changes over time (airline policies, facility operating status) are periodically reviewed, with a "last checked" date shown at the top when updated. If you spot outdated information, let us know using the channel below.

This is reference information
Every number and status on Japan Safe is meant to help you make travel decisions, not to replace official guidance. For actual evacuation and safety actions, always follow Japan Meteorological Agency (JMA) instructions and local announcements or signage.
