Climate Overview
Japan's climate varies dramatically across its 3,000-kilometer length from sub-Arctic Hokkaido in the north to subtropical Okinawa in the south. The main islands of Honshu, Kyushu, and Shikoku experience four distinct seasons with hot, humid summers influenced by Pacific monsoons, cold winters with significant snowfall in mountain and northern regions, and famously spectacular spring (cherry blossom) and autumn (fall foliage) seasons. Tokyo has a temperate climate with rainy season in June-July, hot summers (35°C peak), and cold but relatively dry winters with occasional light snowfall. The typhoon season runs July-October with Okinawa and southwestern Japan most affected.

❄️ Winter

Cold but manageable in central Honshu with Tokyo rarely below -2°C. Heavy snowfall in Hokkaido and Japanese Alps creates world-class ski conditions. Fewer tourists at most sites except ski resorts and Sapporo Snow Festival in February. Onsen bathing season at its most enjoyable.
