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.
