Sports Day long weekend 2026: Japan autumn travel-weather outlook
Oct 10 – Oct 12 · 22 days to go; forecast not yet in range · updated daily
The current seven-day forecast (18 Sep – 24 Sep), not the holiday itself, does not yet reach the Sports Day long weekend 2026, with 22 days to go before it starts. This week, the warmest regions are Kyushu at 32°C, Okinawa at 31.3°C, Shikoku at 31°C and Chugoku at 30.1°C. Cooler conditions are currently in Hokkaido, with a mean high of 23.4°C and a low down to 11°C, followed by Kanto at 26.6°C, Tohoku at 27°C and Hokuriku Shinetsu at 28.1°C.
For the holiday period itself, use the October climate pattern rather than a specific forecast. Japan is usually in a crisp autumn phase, with Tokyo, Kyoto and Osaka around 20 to 24°C, lower humidity and generally comfortable walking weather. Hokkaido is typically further into autumn, with Sapporo at 13 to 17°C and foliage peaking in the first half of the month. Okinawa is still around 27°C, with seas usually warm enough for swimming. Mornings and evenings can cool noticeably, so a light jacket is sensible.
Rain signals are limited in the current outlook: no rainiest regions are highlighted, and all 10 of 10 regions are classed as dry. This week’s suitable city picks include Sapporo in Hokkaido, sunny at 25°C, Morioka in Tohoku, cloudy at 23°C, Chiba in Kanto, cloudy at 24°C, Fukuoka in Kyushu, cloudy at 27°C, and Niigata in Hokuriku Shinetsu, sunny at 28°C. For holiday packing, plan layers: short sleeves may work in milder afternoons, but carry a light jacket for Hokkaido, Tohoku and evening walks elsewhere.
Japan in October: crisp autumn, foliage starts in Hokkaidowhat the holiday period is usually like
October is one of Japan's most pleasant months. The typhoon season is largely over, and Tokyo, Kyoto and Osaka enjoy 20 to 24°C with low humidity and plenty of sun, ideal for long days on foot. Hokkaido's foliage peaks in the first half of the month with Sapporo at 13 to 17°C and a first snowfall possible by month's end; Tohoku peaks in the last ten days.
Highland spots in central Honshu such as Nikko and Kamikochi colour in the second half, while Kyoto and Tokyo wait until November. Okinawa is still around 27°C with swimmable seas. Mornings and evenings cool noticeably, so bring a light jacket.
