Summer in Japan is hot and humid. The season usually begins in June and lasts through August. For visitors traveling from regions with more temperate weather, the heat and the humidity in Japan might be difficult to get used to, but with some planning and strategizing, it is possible to avoid the heat and discomfort.
Late June: Rainy Season in Japan
In late June, in addition to the heat, the humidity level is very high as well. The end of June to early July is known as tsuyu, which is the rainy season in Japan. It is a time of constant rain and even typhoons. During this time, the average daytime temperature in Tokyo is about 22℃, or 71.6℉, and average rainfall is 167.7 mm.
Nevertheless, there are many activities and aspects of Japan that to be enjoyed exclusively during the rainy season, such as viewing the beautiful hydrangeas that bloom during this time throughout the country.
In recent years, summer temperatures have been particularly high, prompting news cautions for people to protect themselves from the heat to avoid heat-related illnesses such as heat strokes. On an average day in July, the temperature in Tokyo can reach highs of 35°C (95°F) in July and August. When outside, stay hydrated with water, wear lightweight clothing, and you bring a fan with you.
High humidity levels are also characteristic for Japanese summer weather, ranging from about 78% relative humidity to 83% relative humidity during July and August. Summer rains are also common, with intense and unpredictable bursts of sudden severe rainfall. It is recommended to carry around an umbrella at all times or have access to a potential shelter from the rain.

Due to the danger of being affected by a heatstroke or heat illness, it is not recommended to spend long hours outside during the daytime.
It is the best time of the year, though, to visit museums and indoor facilities in the metropolitan areas, or to enjoy hiking and festivals outdoors at cool, mountainous areas. We introduce five of the best summer destinations in Japan further below in this article.
July and August are extremely humid and hot, so visitors are recommended to wear thin short-sleeved shirts, one-piece dresses, and clothing with breathable fabric, like cotton. In areas with little shade, it is also advisable to wear a hat with a brim to protect against ultraviolet light and sunburn.
It is important to note that when visiting Shinto shrines and Buddhist temples, you shouldn't wear sleeveless tops or clothing that reveals certain areas of the body. If you plan to make an excursion to a shrine or temple, bring along something to cover up your arms during the visit.
In addition, indoor air-conditioning can make trains, shops, and restaurants feel very cold in contrast to the outside heat, so it is also recommended to have a light jacket or a scarf to feel comfortable.
