Lifestyle
Japan — Living: Climate
Japan spans subarctic, temperate, and subtropical zones across roughly six principal climatic regions. Hokkaido has a humid continental climate with long, very cold winters (heavy snowfall in Sapporo/Asahikawa) and cool summers. The Kanto region (Tokyo) has hot, humid summers, mild winters, and a rainy season (tsuyu) in June-July. The Kansai region (Osaka/Kyoto) is humid subtropical with a similar rainy season plus a typhoon season from late summer into early autumn. Okinawa is tropical, with hot humid summers, mild winters, a rainy season in May-June, and typhoons July-September. Japan has four distinct seasons (spring March-May, summer June-August, fall September-November, winter December-February). The Japan Weather Association's 2026 long-term forecast projects an earlier-than-usual onset and end of the rainy season, extreme summer heat, higher rainfall than 2025, and continued elevated typhoon risk into fall.
Key facts
- Six climate zones from subarctic Hokkaido to subtropical Okinawa.
- Kanto/Kansai: hot humid summers, mild winters, rainy season June-July, typhoon risk late summer-autumn.
- Okinawa: tropical, rainy season May-June, typhoons July-September.
- 2026 forecast: earlier rainy season, extreme heat, higher rainfall, and elevated typhoon risk into fall.
Timelines
- Rainy season (tsuyu), Kanto/Kansai: June-July (earlier onset expected in 2026)
- Typhoon season: late summer through early autumn
Common mistakes
- Assuming Japan has a single uniform climate — conditions differ drastically between subarctic Hokkaido and subtropical Okinawa.
