Silver Week 2026 (Japan): warm south, cooler north, mostly dry

Sep 19 – Sep 23 · the seven-day forecast covers the whole holiday · updated daily

Silver Week 2026 runs from September 19 to September 23, and the forecast covers the full holiday period. The warmest pattern is in western and southern Japan, with Kyushu averaging 32°C, Shikoku 31.4°C, Okinawa 31.2°C and Chugoku 30.4°C for daytime highs. Cooler air is more evident in the north and east: Hokkaido averages 23.4°C with lows down to 12°C, while Kanto averages 26.6°C, Tohoku 27.2°C and Hokuriku Shinetsu 27.8°C. The main travel contrast is therefore between late-summer heat in the south and a more autumn-like feel in Hokkaido.

Rain risk looks limited in the regional summary, with no rainiest regions singled out and all 10 regions counted as dry. That makes the outlook broadly favourable for rail travel, city walks and outdoor sightseeing, though September in Japan is normally a month when typhoons and the autumn rain front can still interrupt plans. For this holiday forecast, however, the drier signal is widespread, with sunny or cloudy conditions among the city picks rather than persistent rain.

For cooler, comfortable sightseeing, Aomori in Tohoku is a strong choice at 23°C and sunny, while Sapporo in Hokkaido is sunny at 24°C and may need a light jacket in the evening. Chiba in Kanto is cloudy at 24°C, suitable for coastal or city plans with a breathable layer. Matsue in Chugoku is cloudy at 26°C, a mild option for walking days, while Nagano in Hokuriku Shinetsu is cloudy at 27°C and works well with short sleeves by day plus a light outer layer. Farther west and south, places such as Tsu at 28°C, Fukuoka at 29°C and Otsu at 29°C call for summer clothing, sun protection and careful pacing in the warmer hours.
