You would need a down jacket, a coat, gloves, and scarves in order to stay warm during winter in Japan. For windy days, wear a knitted cap or ear muffs. For cloudy days, evenings, or when you will stay outside for a longer period of time, be sure to wear warm shoes or boots too. Despite the cold outdoors, it tends to be quite warm inside commercial buildings because of the heating systems, so it is a good idea to wear outerwear that can be easily put on or removed as needed.

Temperature changes drastically during spring in Japan. You would need a thick coat in March while it is still cold, but it gradually gets warmer in April. Bring warm layers such as a cardigan or a jacket to prepare for bad weather, windy days, or a night out. The climate in May is comfortable, so long-sleeved shirts and light cardigans would suffice.

Summer in Japan generally refers to July and August.

What is Summer in Japan Like?

Temperatures during the summer in Tokyo are about 31.5℃ (88.7°F) in the daytime and 24℃ (75.2°F) in the morning and night. In August, it goes up to +33℃ (91.4°F) in the daytime and 26℃ (78.8°F) in the morning and night, with some days feeling about 42℃ (108°F) thanks to the humidity levels.

However, recently it can be as high as 36℃ (96.8°F), about the same as body temperature, so visitors must be extra careful of heatstroke. Be aware of sudden rains and heat lightning as well. Historically, we have something called yūdachi, sudden rain in the hot summer evenings. In these days, we also have guerrilla rainstorm, which is unpredictable and severe rain that can cause flash flooding and landslides as well.

Recommended Clothing for Summer in Tokyo

Since it is very hot and humid in July and August, clothes that let air through, such as light T-shirts, tank tops, or summery dresses, are recommended. Don’t forget UV protection such as a hat when you go outside. It's a good idea to have a very light cardigan or wrap with you to slip on indoors as air conditioning can be quite strong in some places. Please remember though, you are not allowed to wear no-sleeved shirts or something that shows too much skin at shrines and temples. Prepare layers if you plan to visit this kind of places.

September is mostly hot and feels almost like summer, so you can spend the daytime quite easily in a T-shirt. It's a good idea to have something with long sleeves for evenings and in the early mornings, as it can be quite cool or breezy. Long-sleeved shirts would be good enough for sunny days in October.

A light sweater or a hoodie is necessary too, since it gets cold on a bad weather day, and in the morning and at night. For November, most days are cold so be sure to pack a sweater and a jacket. You may need a coat too, if you are particularly susceptible to the cold.
