Rainy Season

The rainy season begins in early June and ends in the first half of July. (It does not visit Hokkaido.) During the rainy season, it rains almost every day. Generally, the rain is not very strong.

Irises and hydrangeas are traditionally considered to be natural beautiy in June in Japan.



It is hot and humid in Tokyo. In August, the temperature rises to more than 30 degrees (more than 35 degrees on some days) in the daytime. I strongly advise you to wear a hat and to take some drink with you.
You can prevent heatstroke by

  1. Wearing a hat
  2. Having some drink constantly
  3. Having some rest in shades when you are out

Fireworks festivals are held in the evening, but the risks of heatstroke remain even in the evening, so Japan Meteorological Agency advises the visitors to have some drink.
I advise you to make a moderate travel schedule to enjoy your trip in summer.





A typhoon is a violent tropical storm with strong winds and rain.
3 or 4 typhoons hit Tokyo a year, mainly between June and October. More typhoons visit Okinawa and Kyushu.
The transportation (including airplanes and trains) is brought to a standstill by their approach. In this case, many airlines, trains and hotels have canceling or rescheduling systems for travelers.



In Tokyo, it snows several times a year. Snow sheets streets around 5 to 20 cm high. There can be some delays or standstills of transportation after it snows.
In Northern Japan, it snows heavily in winter and the ground is covered with deep snow.
