Earthquakes are only the loudest hazard. SHINDO brings ten more into the same calm format — tsunami, weather, rivers, typhoons, heat, volcanoes, radiation, pollen, air and space weather — each from its official source, each explained.
JMA issues weather warnings for individual municipalities across 58 forecast offices. SHINDO finds yours with the Geospatial Information Authority's reverse geocoder and shows only the warnings that apply to it, in JMA's own levels 2 to 5.
JMA's tsunami advisories, warnings and major warnings are shown for each of the 66 coastal forecast zones, with expected heights and arrival times, and pushed as critical alerts for the zones near you.
River flood forecasts (指定河川洪水予報) by level, and every JMA-tracked typhoon with its forecast cone, distance to you and an AI briefing written from the official parameters.
Ministry of the Environment WBGT index for all 47 prefectures, with Apple Watch and widget readouts.
JMA volcanic alert levels (噴火警戒レベル) from the agency's feed.
Live environmental readings from more than a thousand Nuclear Regulation Authority monitoring posts, plus the historical database.
Google pollen forecasts by species, Open-Meteo air quality and NOAA space-weather scales.
Because no reliable method exists. SHINDO shows nothing it cannot trace to a named public source; see Data sources & attribution.
The screen says the source is unavailable instead of showing stale numbers. We audit every feed and publish what we find in our field notes.
Tsunami, weather and river warnings are free. Typhoon tracks, heatstroke, radiation, pollen, air quality and space weather are part of SHINDO Pro.
