Pack: jma · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/jma_forecast for the schema, then POST the same URL with its arguments for the data.

Weather forecast for a Japanese region from the Japan Meteorological Agency (JMA), covering a 3-day short-term outlook (weather, precipitation probability, temperature per sub-area) and a 7-day weekly outlook (weather, precipitation probability, reliability, min/max temperature with confidence range). Sourced from www.jma.go.jp/bosai/forecast/data/forecast/.json. Accepts a place name in English or Japanese (“Tokyo”, “Sapporo”, “大阪”) or a JMA office code directly — resolved the same way as jma_resolve_area. Weather text is native Japanese; an English gloss is included for JMA’s fixed weatherCode set (weatherEn), derived from a static translation table, not machine-translated on the fly.
