Weather in Japan: What to Expect Year-Round

Japan is a year-round travel destination, but the weather can vary a lot depending on where and when you go. Knowing the seasonal changes can help you plan better and pack the right things. Unlike many places, Japan’s seasons are distinct, bringing unique landscapes, festivals, and experiences.

Japan’s Climate

Overall, Japan has four clear seasons—winter, spring, summer, and autumn. The northern part of Japan, such as Hokkaido, experiences much colder weather, while the southern regions like Okinawa stay warm most of the year.

Japan stretches from the cool north to the more tropical south, so there’s a lot of regional variation in the climate. The Pacific Ocean side of the country tends to have milder winters, while the Sea of Japan side gets heavy snow. Summers can get incredibly humid, especially in places like Tokyo, Osaka, and Kyoto.

Best Time to Visit Japan

The best time to visit depends on what you want to do:

Spring (March to May): Ideal for cherry blossom viewing and pleasant weather across most of the country.
Summer (June to August): Great for festivals, hiking, and exploring the northern regions like Hokkaido, but it can get hot and humid in cities.
Autumn (September to November): Beautiful foliage and cooler temperatures make this a perfect season for sightseeing.
Winter (December to February): Best for skiing, snowboarding, and enjoying snow festivals in the northern parts.

Let’s break down the weather month by month to give you a clearer picture of what to expect.

January Weather in Japan

January is winter in Japan, and it can get very cold, especially in the north. Temperatures in places like Hokkaido plunge below freezing, and heavy snowfall is common.

In Tokyo and the central regions, it’s chilly, but you won’t see much snow. The skies are often clear, making this a good time to explore the cities as long as you bundle up.

If you love winter sports, head to places like Niseko in Hokkaido or Hakuba in the Japanese Alps for some of the best skiing and snowboarding in Asia.

What to pack: Warm layers, gloves, a winter coat, and insulated boots if you’ll be in snowy areas.

February Weather in Japan

February continues to be cold, especially in the north, where snow festivals start happening. The Sapporo Snow Festival is a major event that draws visitors to see massive ice sculptures, light displays, and cool activities.

In the southern parts of Japan like Kyushu and Okinawa, February is milder, with temperatures around 10°C (50°F). Tokyo remains cold but dry with clear skies.

If you’re not into skiing, consider checking out hot spring towns like Hakone or Beppu to warm up.

What to pack: Similar to January: bring warm clothing, especially if you plan to visit snowy regions.

March Weather in Japan

March marks the start of spring, but it can still be a bit cold in the early weeks. As the month goes on, the plum and cherry blossoms begin to bloom in southern Japan. By late March, places like Tokyo, Kyoto, and Fukuoka are bursting with pink flowers.

Temperatures hover around 10–15°C (50–60°F) in central and southern Japan. In northern Japan, like Sapporo, winter is still hanging on, though the days are brighter.

What to pack: Layers are key. A light jacket or sweater for daytime and something warmer for evenings.

April Weather in Japan

April is peak cherry blossom season, and it’s one of the most popular times to visit Japan. The weather is mild and comfortable, with temperatures in the low 20s°C (70s°F) in Tokyo and Kyoto.

Northern Japan, including Hokkaido, is just starting to shake off winter toward the end of April. You’ll see cherry blossoms up north after they’ve already peaked in the south.

April is great for walking and sightseeing, as the air is fresh and clear. Be aware that popular places like parks can get crowded.

What to pack: Light layers—a sweater, a jacket in the mornings and evenings, and comfortable shoes for walking.

May Weather in Japan

May brings warmer temperatures all over Japan, with highs reaching around 25°C (77°F) in places like Tokyo and Osaka. You’ll also start seeing more greenery as spring fully takes hold.

This is a great time for outdoor activities before the rain hits in June. Hiking in national parks is popular, especially around Mount Fuji, though climbing the mountain itself isn’t allowed until July.

What to pack: Comfortable breathable clothing, a light jacket, and sunscreen for sunny days.

June Weather in Japan

June is the beginning of the rainy season (Tsuyu) in Japan, lasting through early July. You’ll encounter a lot of rain and humidity, especially in central and southern Japan.

Temperatures in Tokyo rise to around 27°C (80°F), but the dampness can make it feel warmer. Northern Japan, particularly Hokkaido, doesn’t get as much rain, making it a decent destination during the rainy season.

What to pack: A light waterproof jacket, umbrella, and shoes that can handle rain.

July Weather in Japan

July is hot and humid. In cities like Tokyo and Kyoto, temperatures often reach over 30°C (86°F). Expect high humidity, which can make sightseeing uncomfortable if you’re not used to it.

July also marks the official opening of Mount Fuji’s climbing season. If hiking is in your plan, this is the best time to climb Japan’s tallest peak.

What to pack: Breathable clothing, a hat, sunscreen, and lots of water. If you’re climbing Mount Fuji, bring warm layers for the summit.

August Weather in Japan

August continues with the intense heat and humidity, peaking around mid-August. Temperatures can go as high as 35°C (95°F) in cities. Air conditioning will become your best friend.

It’s a great time to visit Hokkaido, where summers are cooler, with highs around 25°C (77°F). This is also festival season, so you can enjoy some of Japan’s best cultural festivals like Obon and fireworks shows.

What to pack: Lightweight clothes, sunscreen, hat, and sunglasses. Stay hydrated!

September Weather in Japan

September is the tail end of summer, and the temperatures begin to drop. Central and southern Japan are also prone to typhoons during this time, so it’s good to keep an eye on the weather forecasts.

Despite the potential for storms, temperatures become more comfortable, ranging from 20–28°C (68–82°F). Northern Japan is cooler and less affected by typhoons, making it a good option for travel this month.

What to pack: Rain gear for potential typhoons, lightweight clothing, and packing in layers.

October Weather in Japan

October brings cooler, pleasant weather perfect for sightseeing and outdoor activities. The summer heat fades, and you’ll start to see autumn colors in northern Japan, especially in Hokkaido and the Japanese Alps.

Temperatures in places like Tokyo and Kyoto stay around 15–22°C (59–72°F). This is one of the best months to explore Japan, as it’s relatively dry and comfortable.

What to pack: Light layers, perhaps a jacket for the evenings.

November Weather in Japan

November is peak season for autumn leaves, drawing visitors to places like Kyoto and Nara. The temperatures across Japan cool down further, staying in the low to mid-teens (°C). It’s a great time for photography and hiking.

Sunny days and clear air make for comfortable travel, especially if crowds don’t bother you.

What to pack: Sweaters, a light jacket, and comfortable shoes for walking.

December Weather in Japan

December kicks off winter, with temperatures dropping significantly in the northern and central regions. In cities like Tokyo, it stays cool but not freezing, with highs around 10°C (50°F). Snow begins to fall in the mountainous areas, opening up the ski season toward the end of the month.

This is also when you’ll see beautiful winter illuminations in various cities, especially around Christmas.
