How this forecast is built

Each day's crowd level combines the landmark's baseline popularity, Japanese national holidays (computed from the official rules, including substitute holidays), curated local festival and season windows, a national tourism seasonality curve derived from published visitor-arrival patterns, and live rain probability from the Japan Meteorological Agency — weighted by how much that specific place actually empties out in the rain.

It's a model, not a measurement. It's good at "this weekend will be much worse than the following Tuesday" and it is not a headcount. Days beyond the JMA's ~7-day window use seasonal rain climatology.
