How this service works
List active meteorological warnings and advisories (気象警報・注意報) for a Japanese (JP) region — heavy rain, storm, snow, flood, storm surge, emergency (特別警報) tiers — sourced live from 気象庁 (JMA).
Output
A structured list of currently active meteorological warnings and advisories for the requested Japanese region, including the type of alert (heavy rain, storm, snow, flood, storm surge, etc.), severity tier (注意報, 警報, 特別警報), and the specific area or sub-region affected — all sourced live from JMA.
Example use cases
Travel safety check before departure
“I'm flying into Osaka tomorrow morning — can you check if there are any active JMA weather warnings or advisories for the Osaka area right now, like heavy rain, storm, or special emergency alerts?”
Disaster monitoring dashboard alert
“Check the current JMA warnings and advisories for Kumamoto prefecture and let me know if any flood, heavy rain, or special emergency 特別警報 alerts are active.”
Real-time snow warning check for Hokkaido
“Are there any active snow or blizzard advisories from JMA for Hokkaido right now? I want to know all warning tiers that are currently in effect.”

Endpoint
GEThttps://weather.agentic-jp.com/warnings/:areaWhen to prefer
Choose this endpoint when you need real-time, authoritative JMA-sourced meteorological warnings and advisories for a specific Japanese forecast region. Prefer it over general weather forecast endpoints when the user's concern is active alert status, safety decisions, or disaster preparedness rather than predicted conditions or temperature. Ideal for monitoring workflows, travel safety checks, and public-safety dashboards focused on Japan.
Side effects
- Invalid or unrecognized area code returns an error or empty result
- No active warnings returns an empty list (not an error — normal when conditions are calm)
- JMA upstream outage may cause stale or unavailable data
- Malformed area parameter causes a 400-level response
