More Details Connect to Claude

The Japan Meteorological Agency (JMA) — the world's most respected earthquake and weather authority — as a single MCP server, straight from the JSON endpoints that power jma.go.jp.

What you can do

  • Recent earthquakes — the latest JMA bulletins with epicentre region (Japanese + English), coordinates, magnitude and max seismic intensity on Japan's famous 0-7 scale, plus per-city intensity breakdowns
  • Full event reports — detailed quake reports per prefecture/city, exactly as issued
  • Live weather warnings — active warnings and advisories per prefecture office (Tokyo 130000, Osaka 270000, Sapporo 011000...) with status (issued/ongoing/released)
  • Official forecasts — 3-day detailed forecasts (weather code, wind, waves) + weekly trends for every prefecture area
  • Real-time disaster feed — the JMAXML high-frequency feed: earthquakes, volcanic bulletins and tsunami notices the moment they are published

Why JMA and not USGS?

USGS gives global locations and magnitudes; JMA gives what actually matters in Japan: the Shindo seismic-intensity scale (0-7) measured at thousands of stations, per-city intensity reports, official Japanese warnings, volcanic bulletins and tsunami notices. When Japan says "intensity 6+", this is the source.

Who is this for?

Travel safety briefings, earthquake-aware applications, news monitoring, researchers, expats and anyone building agents that need authoritative Japan disaster + weather data.

6 tools expose this connector's capabilities to your AI agent.

get_recent_earthquakes

Some entries are tsunami-related bulletins. Filter client-side by region or magnitude as needed. List recent Japan earthquakes with epicentre, magnitude and max seismic intensity (JMA official)

get_earthquake_detail

Japanese original with structure intact. Get full JMA report for one earthquake (cities with seismic intensity, epicentre details)

get_weather_warnings

headlineText summarises current warnings in Japanese; status values like 継続 (ongoing), 発表 (issued), 解除 (released). Empty warnings array = all clear. Get ACTIVE JMA weather warnings and advisories for a prefecture (weather + earthquake early warning areas)

get_weather_forecast

Areas are sub-prefecture regions with codes (Tokyo 130000 → 東京地方 130010, 伊豆諸島 130020...). weatherCodes map to icons: 100=clear, 200=cloudy, 300=rain, 400=snow, 2xx/3xx variants — combine with warnings for safety briefings. Get official JMA weather forecast (3 days + weekly) for a prefecture area

list_office_codes

Japan has 47 prefectures but 46 offices (Hokkaido is split: 011000 Sapporo, 012000 Hakodate, 013000 Asahikawa, 014100 Kushiro/Obihiro; Okinawa = 471000). Reference table of JMA prefecture office codes (46 offices incl. Hokkaido split and Okinawa)

get_disaster_feed

g. 震源・震度に関する情報 = epicentre/intensity info, 火山の状況 = volcano status, 津波警報 = tsunami warning), update times and detail XML paths. Use to catch events that have no earthquake-list entry yet (volcanic activity, tsunami advisories). Browse the JMA real-time disaster feed (earthquakes, volcano bulletins, tsunami) as a structured list
