Why Koyo Needs Live Data

Autumn color timing shifts every year by region, elevation, and temperature. Maple and ginkgo also peak on different schedules. Japan in Seasons keeps these separate so AI assistants can answer with real timing instead of a generic November recommendation.

The current-year autumn forecast is published closer to autumn. Before that feed appears, the MCP clearly labels prior-season koyo data as reference instead of presenting it as a fresh forecast.
