When is the best season to visit Japan? Rainy season, snow, and heatwaves

Japan is the country with the most climate zones in the world.

From high mountain climates like the Alps to cold climates like Alaska, Pacific climates like Hawaii to Mediterranean climates, this archipelago has it all.
This means that you can always do your favourite activities, depending on the time of year and the location!

A. Hokkaido: Cold climate

Famous places include Sapporo, Niseko, and Furano.

There are differences between the north and south sides. In the north (Japan Sea side, such as Sapporo), it snows a lot in the winter. Summer is comfortable and dry.
In the south (Pacific Ocean side, such as Kushiro), it is very cold in the winter but doesn’t snow much. In the summer, it is very foggy.

B. Japan Sea side: Humid subtropical & dry summer

Famous places include Amanohashidate, Ine, Kanazawa, and Kinosaki.

Temperatures vary between the north(such as Aomori) and south(such as Miyazu), but summers are dry and mostly sunny, while winters are rainy or snowy throughout the year, with a rainy season from late June to early July. Typhoons rarely come.

C. Pacific side: Humid subtropical & dry winter

This is the region where most of Japan’s population is concentrated (such as Tokyo, Kyoto) and where industrialization is most advanced. Summers are extremely hot and humid, but winters are sunny. There is a rainy season from late June to early July, and typhoons often come from August to October. This is also an area that is prone to earthquakes and tsunamis.

A completely new climate zone: Urban

Like many cities around the world, Japan is highly urbanized and the climate is changing dramatically, especially in Tokyo and Osaka.

More and more Japanese and foreigners are flocking to the cities, where the heat from air conditioners and cars makes it hotter, and then people turn on even more powerful air conditioners… creating a vicious cycle that makes summers hotter and hotter.
Every year many children and elderly people die from heatstroke, so be careful of the risk to your life if you go to Tokyo, Kyoto, or Osaka in the summer.
Conversely, in winter the concrete jungles block out sunlight and the wind from the buildings makes you freezing.

However, the number of Japanese people living in cities and tourists going to cities continues to increase, and the countryside where I live is becoming less and less crowded. However, it has become cooler and more comfortable. I definitely recommend traveling to the countryside of Japan!
