Safenity Japan

Safenity Japan compares public safety statistics across Japanese prefectures and municipalities.

Recent earthquakes and evacuation maps
Open an official GSI map in your browser, centered on your selection. Choose designated emergency evacuation sites for earthquakes or designated shelters. These serve different purposes; designation does not mean a facility is open. Check hazard suitability and whether facilities are open and accepting evacuees with the municipality. The app does not provide routes or check route safety.
Recent earthquakes retrieves JMA reports via P2P Quake and refreshes every 60 seconds while this screen is in the foreground. Distances to nearby reporting stations are calculated on your device. Your GPS coordinates and selected area are not sent to P2P Quake. A station reading does not describe the intensity at your exact location. Reports estimating intensity at 5 lower or higher without a measured value are labeled as such.
Regional intensities are usually announced about 90 seconds after an earthquake, and detailed observations after about 5 minutes. Delivery to the app may take longer or fail. This feature provides no earthquake early warnings, forecasts, or background notifications.
Recent reports and external maps require internet. P2P Quake receives normal connection data, including your IP address. Opening the external map shares the selected center coordinates with GSI.

Data notes
Crime data uses the latest available public prefectural or police statistics for each area, including 2025, 2024, or 2023 sources. Rates generally use 2020 resident population. Futaba Town alone uses Fukushima Prefecture’s resident-register population of 5,294 as of January 1, 2025, with its population year and source shown. The adjusted map score is a separate indicator from the resident rate in comparison cards.

Earthquake view shows the highest sampled probability of JMA intensity 6 lower or higher within 30 years, using J-SHIS 2024 data. This is not a probability for the whole area or an all-hazard forecast or alert service.

Bundled statistics support offline search and comparison; map tiles require internet. Location is optional for map centering and nearby station searches. No account, ads, operator behavioral analytics SDK or real-time alerts. GSI receives the IP address and requested map area, retains logs and analyzes them internally. See the privacy policy.

The figures help interpret public statistics; they do not guarantee safety. Tokyo town-level data is a reference layer and does not cover every neighborhood.

The interface supports Japanese, English, Korean, Simplified Chinese and Traditional Chinese. Area names use Japanese and available Romanized labels. The Recent earthquakes screen uses official JMA translations for epicenter names; station names and names without an official translation remain in Japanese.
