Eleven hazards

One feed for everything Japan throws at you.

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.

Your municipality, not your prefecture.

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.

Tsunami

Warnings by coastal zone, with the expected height.

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.

Rivers and typhoons

Designated-river flood forecasts and the storm's track.

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.

The ten other hazards

01

Heatstroke

Ministry of the Environment WBGT index for all 47 prefectures, with Apple Watch and widget readouts.

02

Volcanoes

JMA volcanic alert levels (噴火警戒レベル) from the agency's feed.

03

Radiation

Live environmental readings from more than a thousand Nuclear Regulation Authority monitoring posts, plus the historical database.

04

Pollen, air, space

Google pollen forecasts by species, Open-Meteo air quality and NOAA space-weather scales.

Good to know

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.
