Japan temperatures, all on one screen
Japan's highs span 16°C as cooling develops: 2026-11-12
Okinawa is Japan's warmest region, with a high of 27°C, while Hokkaido is the coolest at 11°C. The spread between those regional highs is 16°C, a substantial contrast for anyone planning clothing for travel between them. The national mean high is 19.9°C, putting the overall picture well below Okinawa's warmth but comfortably above Hokkaido's cooler conditions.
The seven-day outlook points to cooling, with the national mean high easing by about 3°C to 17°C. Chugoku has the largest fall, cooling by 6°C over the period. Hokuriku Shinetsu follows with a decline of 4°C, while Tohoku eases by 3°C. Clothing suited to today's afternoon warmth will need an extra layer as those regions cool.
At city level, Naha (Okinawa) leads with a high of 27°C, favouring lighter clothing during the warmest part of the day. Kagoshima (Kyushu) reaches 23°C, while Tottori (Chugoku) reaches 22°C. The cooler contrast is marked in Kushiro (Hokkaido), where the high is 8°C; Morioka (Tohoku) and Sapporo (Hokkaido) both reach 11°C, making warmer daytime layers more appropriate.
Day-to-night differences also matter when choosing what to wear. Yamagata (Tohoku) drops from 17°C to 2°C, a range of 15°C that calls for layers beyond afternoon clothing. Yamaguchi (Chugoku) has the same range, moving from 20°C to 5°C. Aomori (Tohoku) falls from 15°C to 1°C, so a warm outer layer is useful outside the warmer daytime hours.

Japan in November: Kyoto's foliage season, first snow in the north
In November the foliage front reaches Honshu's cities: Tokyo colours in the second half and Kyoto peaks from late November into early December, with highs of 13 to 18°C, nights of 5 to 8°C and distinctly cold temple mornings. Skies are mostly clear and dry in one of the least rainy stretches of the year, and it is one of the busiest months for visitors.
Hokkaido enters early winter, with Sapporo at 5 to 9°C and lasting snow cover from mid to late month; the Sea of Japan side turns grey and stormy. Okinawa stays mild at 23 to 25°C. In Kyoto, start early to beat the midday crowds at the famous gardens.
