# weather.agentic-jp.com

This host serves as a reference data layer for JMA-based weather integrations in Japan. It exposes a single skill that enumerates all 58 JMA forecast offices with their codes and names, enabling agents to resolve human-readable prefecture or region names into the numeric codes required by downstream JMA weather forecast endpoints. It does not itself provide forecasts or current conditions.

## When to use this host

Use this host when an agent needs to resolve a Japanese prefecture or region name to a valid JMA forecast office code prior to calling a weather forecast API. Do not use this host to retrieve actual weather forecasts, current conditions, or historical weather data — it only returns area reference metadata. If you already have a valid JMA area code, this host adds no value. For actual forecast data, route to a JMA-compatible weather forecast endpoint that accepts the area codes this host provides.

## Capabilities

### Area Code Discovery

Returns the complete catalog of JMA forecast office identifiers, allowing agents to look up valid area codes and names before querying a weather forecast endpoint.

- **`fetch-weather-areas`** — Returns the full catalog of 58 JMA forecast offices in Japan with numeric codes, Japanese and English names, and class10 sub-regions, for use as valid area identifiers in weather queries.

## Skill reference

### `fetch-weather-areas`

**Weather Areas** — Returns the full catalog of 58 JMA forecast offices in Japan with numeric codes, Japanese and English names, and class10 sub-regions, for use as valid area identifiers in weather queries.

*Use when:* Use when an agent needs to discover valid area codes or names for Japanese weather forecast queries, such as resolving a prefecture or region name to its JMA forecast office code before calling a weather endpoint.

*Not for:* Do not use for retrieving actual weather forecasts or conditions; use a weather forecast endpoint with a specific area code instead.

**Returns:** Returns a JSON object with count=58 and an areas array of JMA forecast offices, each containing a 6-digit code, Japanese and English names, the responsible observatory name, and nested children sub-regions.

**Example:** `GET https://weather.agentic-jp.com/areas`
