Japan Weather: Seasons, Climate & Best Time to Visit
Japan’s weather is as diverse as its culture — ranging from snowy mountains in Hokkaido to tropical beaches in Okinawa. Understanding Japan’s climate and seasons is key to planning your trip and packing appropriately. This complete Japan Weather Guide explains regional differences, seasonal highlights, and practical tips to help you enjoy every moment of your journey across the Land of the Rising Sun.
Overview of Japan’s Climate
Japan has a temperate climate with four distinct seasons, though regional variations are significant. Northern Japan (Hokkaido) experiences long, snowy winters and mild summers, while southern regions such as Okinawa enjoy a subtropical climate with warm weather year-round. Coastal areas like Tokyo and Osaka have humid summers and cool, dry winters.
The country’s geography — stretching over 3,000 km north to south — means temperatures and rainfall can differ drastically between regions at the same time of year. For example, in January, Sapporo may be below freezing while Okinawa remains around 20°C.
Spring in Japan (March–May)
Spring is one of the most popular seasons to visit Japan, thanks to the world-famous cherry blossoms. The weather is generally mild, with average daytime temperatures between 10°C and 20°C (50°F–68°F).
- March: Still cool, especially in northern Japan. Cherry blossoms begin in Kyushu and Shikoku.
- April: Ideal weather across most regions — Tokyo, Kyoto, and Osaka are in full bloom.
- May: Warm and comfortable before the rainy season begins. Perfect for outdoor sightseeing.
Pack layers — mornings and evenings can still be chilly. Don’t miss events like Hanami (cherry blossom viewing) in parks and temples across the country.
Summer in Japan (June–August)
Summer brings heat, humidity, and festivals. Temperatures average between 25°C and 35°C (77°F–95°F), especially in central and southern Japan. June marks the beginning of the rainy season (tsuyu), which lasts until mid-July in most areas.
After the rains, skies clear for vibrant summer festivals like Gion Matsuri in Kyoto and Sumida River Fireworks in Tokyo. It’s also hiking season in the Japanese Alps and climbing season for Mount Fuji (July–early September).
- June: Humid with occasional rain; fewer crowds.
- July–August: Hot and sunny — perfect for beach trips or mountain adventures.
Light, breathable clothing is essential, along with a hat and sunscreen. In coastal regions, pack a swimsuit and mosquito repellent.
Autumn in Japan (September–November)
Autumn is another magical season in Japan, famous for its koyo (autumn foliage). The weather cools down after summer, offering clear skies and pleasant temperatures between 15°C and 25°C (59°F–77°F).
- September: Typhoon season peaks; expect heavy rain and wind in some regions.
- October: Crisp air and golden landscapes — one of the best times to visit Kyoto and Nikko.
- November: Peak autumn color season, especially in Kansai and Tokyo areas.
Bring a light jacket for evenings. Hiking, photography, and temple visits are ideal during this period — nature is at its most colorful and peaceful.
Winter in Japan (December–February)
Japan’s winter is a wonderland for snow lovers. The north experiences heavy snowfall, while central and southern Japan remain cold but dry. Average temperatures range from -5°C in Hokkaido to 12°C in Tokyo and 20°C in Okinawa.
- December: Festive lights and holiday markets appear across major cities.
- January–February: Peak ski season — Hokkaido, Nagano, and Niigata offer world-class resorts.
Hot springs, known as onsen, are a winter highlight — especially in Hakone, Beppu, and Noboribetsu. If visiting rural areas, pack thermal wear and waterproof boots.
Regional Climate Differences
Because of Japan’s long shape and varying topography, regional climates differ greatly:
- Hokkaido: Cold, snowy winters and cool summers; best for skiing and snow festivals.
- Tokyo & Honshu: Humid subtropical climate — hot summers, mild winters.
- Kansai (Kyoto, Osaka): Warm and humid in summer; pleasant spring and autumn.
- Kyushu: Mild winters and early cherry blossoms; risk of typhoons in late summer.
- Okinawa: Tropical year-round; ideal for beach vacations from April to October.
Plan your trip based on the experiences you want: skiing in Hokkaido, cherry blossoms in Kyoto, or island hopping in Okinawa.
Travel & Packing Tips

- Pack in layers — temperatures vary greatly between regions.
- During tsuyu (rainy season), carry a compact umbrella or rain jacket.
- Winters are dry in central Japan — pack moisturizer and lip balm.
