Seasonal Difference

Japan is said to have a varied climate with four distinct seasons, with Aomori Prefecture particularly known for its distinct seasonal changes. In spring, beautiful cherry blossom brings joy, and in summer local unique festivals like Nebuta Festival are held in each region. Each fall, mountains and streams are decorated with autumn leaves, and snow in winter creates fantastic scenery and opportunity for winter sports like ski or snowboard.

Climates in each area

With the “Ou Mountain Range” located in the center of the Aomori Prefecture, the land is divided into two distinct climates on the side of the Sea of Japan and Pacific Ocean. The side of the Sea of Japan is called as “Tsugaru region” and that of the Pacific Ocean is as “Kennan region”, and character of climates are different for each region.

Tsugaru region

The cold humid air in winter collides with the Ou Mountain Range, which causes heavy snowfall in the region.

In summer, Tsugaru region has warm summers with higher temperature.

Kennan region

In the summer, the cool humid easterly known as “Yamase” creates many days of low temperature and high humidity in the region. In winter, the region has mostly fine and dry climate, with less snowfall and longer sunshine hours.

Temperature, Precipitation and Snowfall

Comfortable weather with average temperatures of around 23 ℃ can be experienced in Aomori’s summers, however as the graph below shows, it is lower in the Pacific Ocean side than the Sea of Japan side. And in winter, the Tsugaru region sees higher precipitation and snowfall than the Kennan region. Aomori Prefecture sees different conditions for each region, even in same season. Why don’t you experience the unique characteristics by visiting each area in the same season?

Summer (Jul – Aug)

The rainy season usually ends around mid-July — when it is recommended to have an umbrella due to the frequency of rain.
