Introducing Weather & Typhoons

The storm is 2,625 km away.
SHINDO already knows.

Weather that tells you what to do

Japan's weather warnings are precise, official and written in a code most people never learned. SHINDO reads the Japan Meteorological Agency's warnings for your exact municipality — heavy rain, heavy snow, storms, floods, high waves — and tells you in plain words what changed and what to do. When a typhoon forms, it tracks every JMA bulletin and asks AI to read the news for you, so you get the facts in one minute instead of ten tabs.

Weather advisory alerts

Rain, snow, wind. Alerted before it reaches your street.

When JMA issues an advisory, warning or emergency warning for your municipality, SHINDO pushes it — named in your language, with one line on what to do. Choose a hazard to see how it arrives.

Hazard
JMA level

Example notification. Levels follow JMA's own system — thunderstorms are only ever an advisory, and floods have no emergency level.

Live typhoon tracker

The circle grows. The storm doesn't.

Every JMA forecast point carries a circle: the storm's centre has roughly a 70% chance of being inside it at that hour. It widens with time because the forecast gets less certain — not because the typhoon gets bigger. SHINDO draws every circle and says so in plain words.

Schematic. Circle sizes are to scale with each other, using Typhoon Champi's JMA forecast of 17 Oct (±45 → ±220 km); the track shape is illustrative.
