Japan’s climate varies significantly depending on the region, spanning subtropical islands in the south to snow-covered mountains in the north. While many compare central Japan’s weather to that of the northeastern United States, with hot summers and cold winters, regional differences make Japan a year-round destination, each season offering something unique.
Summer (June–September): Hot, Humid & Rainy
Summer in Japan is hot and humid, especially in cities where the concentration of buildings restricts airflow, making streets feel even warmer.
- Hottest months: July to September, with temperatures averaging in the high 20s°C to mid-30s°C, though southern areas like Okinawa can reach even higher.
- Humidity: Can make it feel even hotter, with sticky, muggy nights, particularly in urban areas like Tokyo and Osaka.
- Rainy season (Tsuyu): Typically in June, bringing persistent rain, though northern Japan (Hokkaido) experiences less.
- Typhoon season: Peaks in September, often bringing heavy rain and strong winds to coastal and southern regions.
Autumn (October–November): Cool & Colourful
Autumn is one of the best times to visit Japan, with comfortable temperatures and stunning autumn foliage (koyo).
- Temperatures: Generally between 15–25°C, with cooler mornings and evenings.
- Best areas for autumn colours: Kyoto, Nikko, and the Japanese Alps, where red and golden maple leaves create breathtaking scenery.
- Lower humidity: Making travel, hiking, and sightseeing much more comfortable than in summer.
Winter (December–February): Snowy & Chilly
Winter temperatures vary widely across Japan, from mild coastal cities to deep snow in the mountains.
- Coldest month: January, with Tokyo averaging around 9°C, while northern Japan (Hokkaido and Tohoku) experiences subzero temperatures and heavy snowfall.
- Snowfall:
- Minimal in cities like Tokyo, Osaka, and Hiroshima, where snow rarely settles.
- Heavy in the Japan Alps and northern regions, making Japan a top destination for skiing and snowboarding in places like Niseko, Hakuba, and Nozawa Onsen.
- Winter festivals: The Sapporo Snow Festival in February features elaborate ice sculptures and attracts visitors worldwide.
Spring (March–May): Cherry Blossoms & Mild Weather
Spring is one of the most popular times to visit Japan, thanks to comfortable temperatures and breathtaking cherry blossoms.
- Temperatures: Ranging from 10–20°C, warming gradually as April and May approach.
- Cherry blossom season (sakura): Peaks in late March to early April in most areas, though blossoms bloom earlier in Kyushu and later in Hokkaido.
- Fresh breezes and clear skies make it an ideal time for outdoor activities and sightseeing.
Best Times to Visit Japan
- Ideal seasons: Spring (March–May) and Autumn (October–November) offer the best balance of mild weather, fewer typhoons, and stunning scenery.
- Avoid peak crowds: Golden Week (late April–early May), Obon (mid-August), and New Year’s (late December–early January) are the busiest and most expensive times for travel.
- Winter sports: Visit from December to February for skiing and snowboarding in Hokkaido or the Japanese Alps.
- Cherry blossoms & autumn leaves: Book early if visiting in sakura season (March–April) or autumn foliage season (October–November), as accommodation fills up fast.
Japan is a year-round destination, but choosing the right season depends on what you want to experience—whether it’s cherry blossoms in spring, autumn colours, winter snow, or summer festivals!
