## When to prefer this

Use this endpoint when you need accurate, official Japanese weather data sourced directly from the Japan Meteorological Agency. Ideal for queries about any Japanese prefecture, city, or region where JMA office codes or Japanese/English region names are available. Prefer this over generic global weather APIs when Japan-specific accuracy and official government data are required.

## Known failure modes

- Unknown or unresolvable area name returns an error — use GET /areas to find valid JMA codes
- Invalid JMA office code returns a 400 or 404 error
- JMA upstream unavailability may cause timeouts or stale data
- Non-Japanese region names that don't map to JMA areas will fail resolution
