How are the Japan travel scores calculated?
Every city is rated 0-10 per month using ERA5 climate normals - temperature, precipitation, humidity, daylight, and days with 6+ hours of sunshine.

Climate data: Open-Meteo ERA5 historical archive, the five most recent complete years (2021–2025). Scores are monthly averages for that window, not forecasts, and short-window precipitation can differ from longer-term normals. “Sunny days” count days with at least 6 hours of measured sunshine — they are not dry days.
