What to Wear in Japan: Weather by Month

One thing I always tell my clients is don’t pack based only on the weather in Tokyo.
Japan is a long country, and the weather can be very different depending on the season and where you’re going.

Here’s a general idea of what to expect by month.

🌸 March–May | Spring 春

March: Still pretty chilly, especially in the morning and evening. I would bring a warm jacket and layers.

April: This is one of my favorite times to travel, but don’t let the cherry blossoms fool you into thinking it’s warm! It can still be quite cool, especially early in the morning or at night. A light-to-medium jacket is a good idea.

May: Usually much more comfortable and warmer. Light layers and a light jacket should be enough for most places.

☀️ June–August | Summer 夏

June: The rainy season usually starts around June. It can be warm and humid, and you may have some rainy days. I recommend a lightweight rain jacket and a compact umbrella.

July: Hot and humid. Very hot. 😅 Wear lightweight, breathable clothing and expect to sweat if you’re walking around during the day.

August: Pretty much the same as July, and often very hot and humid. If you’re visiting Okinawa, it will feel even more tropical.

One thing you might notice in Japan during the summer is that people tend to cover up more than you might expect, even when it’s really hot.

You’ll often see people wearing long sleeves, carrying parasols, and wearing hats to protect themselves from the sun.
Tank tops and very short shorts are also less common than they are in the U.S.

Of course, there is no rule saying you can’t wear them! But if you wear something that shows a lot of skin, you might sometimes feel like people are looking at you. Showing a lot of skin is simply not as common in Japan, and some more conservative people may feel that an outfit is a little too revealing. 😓

I wouldn’t worry too much about it, though. This is more of a cultural difference than a rule you need to follow.
Just knowing this ahead of time may help you understand why you might get a few curious looks.

🍁 September–November | Fall 秋

September: It can still feel like summer, especially in the first half of the month. Don’t pack a heavy fall wardrobe just because it’s September.

October: Usually much more comfortable. Light layers, a sweater, and a light jacket are good choices. If you’re going to the mountains, bring something warmer.

November: Cooler, especially in the morning and evening. A sweater and jacket are usually helpful, and you may want a warmer coat toward the end of the month.

❄️ December–February | Winter 冬

December: Cold, but usually not extremely cold in places like Tokyo and Kyoto. A warm coat and layers should be comfortable.

January: One of the coldest months. Bring a warm coat, sweater, and warm socks. If you’re sensitive to cold, Heattech or another thermal layer is very helpful.

February: Similar to January. It can be cold, although you may start to notice a little change toward the end of the month.

If you’re visiting Hokkaido, the Japanese Alps, Tohoku, or other snowy/mountainous areas, you’ll need to prepare for much colder weather than you would in Tokyo or Kyoto.

🏔️ And one more thing…

If your itinerary includes several different regions, check the weather for each destination, not just Tokyo.

For example, you could leave Tokyo wearing a light jacket and arrive somewhere in the mountains where you suddenly wish you had brought a much warmer coat. 😂

Japan also involves a lot of walking, so comfortable shoes are probably the most important thing you can pack.
You may walk much more than you expect between train stations, sightseeing spots, restaurants, and your hotel.

I always recommend dressing in layers whenever possible. It makes it much easier to adjust throughout the day.
