Color-Coded Hazard Layers on the Map

Overlay flood, landslide, tsunami, storm surge, liquefaction, and designated danger zone layers on the map in color. Switch layers on and off with one tap, and choose a spot by searching an address or place name, or just tapping the map.

Tap Any Spot to See Its Risks, Most Severe First

Pick a location and get a list of its risks — landslide, tsunami, storm surge, designated danger zone, flood, and liquefaction — with the most severe at the top. An overall summary and any warnings in effect are shown alongside, so you get the key points at a glance. Where no data is available, the item is marked "No Data."

Alert Levels, Warnings, and Advisories from the Japan Meteorological Agency

See the alert levels (heavy rain, landslide, river flooding, storm surge) and the warnings and advisories issued for your area, exactly as published by the Japan Meteorological Agency (JMA). The app does not send push notifications, so open it to check the latest information.

• Recent earthquakes (intensity and magnitude) and tsunami warning status
• Street View of the area around the selected spot (Google Street View)
