What this cannot tell you
- Quieter is relative. A quieter month is a smaller share of that place's own year, not fewer visitors than somewhere else.
- One weather station per city. Coasts, mountains and city centres differ; these are long-term averages, not a forecast.
- Country and prefecture totals. How busy a month is comes from the whole country or prefecture, not the city.
- 2025 only. One year of visits; events and holidays move between years.
- Not a recommendation. The list says where the weather and the timing line up, not where you would enjoy more.
Key takeaways
- August was Wakayama's busiest month of 2025 (11.2% of the year).
- Closest weather in a quieter month: Matsuyama, Ehime.
- 8 prefectures in Japan matched our rule for August.
- What we would skip: choosing on this list alone. Open each place, check its holidays and the dates you have in mind.
