Weather in Japan's Major Cities in July

Tokyo and Central Japan: Hot and Humid, but Full of Festivals

• Tokyo, Kyoto, Osaka, and Mount Fuji

High rainfall hits the major cities of Tokyo, Kyoto, and Osaka in central Japan in the first half of July, with an average rainfall of 6 in (158 mm). However, it doesn't rain every day and the rainfall decreases toward the end of July.

The temperature gets up to 86°F (30°C) on average, which seems hotter with the humidity. So, you're advised to do any outdoor activities in the early morning or late afternoon.

In Tokyo, Kyoto, and Osaka, abundant indoor activities in air-conditioned buildings offer a cool and dry escape, especially for families with teenagers.

A private tour with us would make your Japan trip more comfortable: enjoy a private air-conditioned car, cold drinks that are always on hand, and flexible itineraries that make the best of the weather.

July is the ideal time to climb iconic Mount Fuji in Japan as it is only open for climbing from early July to early September. You would likely encounter the most favorable weather for this adventure in late July.

Festivals: July is the best time to fully immerse yourself in Japanese festival celebrations. You could wear yukata (Japanese traditional summer clothing) to appreciate the huge parades and watch fantastic fireworks displays. For example:

• The Sumidagawa Fireworks Festival in Tokyo (late July)
• Gion Matsuri in Kyoto (the whole of July)
• Tenjin Matsuri (a summer festival with dance, music, and processions) in Osaka (July 16–26 in 2025)

Costs and Crowding

Because of the rainfall, you should expect smaller crowds and costs in the first half of July.

When Japanese school vacations begin in mid-July, domestic travelers begin their summer trips. Attractions become much busier than before. Accordingly, hotels and airlines are in high demand. The cost of hotels and international flights at the end of July is usually about 10% more expensive than at the beginning.

Considering the escalating prices and busyness, we suggest you book at least 3 months in advance to guarantee your rooms in late July. If you need family rooms, contact us to book them at least half a year in advance for you.

What Should I Wear in July?

It is still advisable to carry around rain gear and waterproof clothing with you in July, particularly in central and southern Japan. Lightweight and breathable clothing is recommended for hot and humid days.

For traveling in Japan in July, pack plenty of sunscreen, a sun hat, and good sunglasses due to the high UV levels.

Insect repellent is helpful to protect you during outdoor activities, especially in the mountains or national parks.
