The Climate in Japan
Japan has six different climate regions. These include Hokkaido, the West Coast of the Sea of Japan, the Central Highlands, the Seto Inland Sea, the Pacific Region and the Ryukyu Islands. The climate is generally influenced by the rainy season Tsuyu, in English “plum rain”, which takes place in the summer months. During this time, precipitation is particularly high and with the combination of high temperatures and high humidity, it can be tough for European visitors. The winds also play a big role in the climate in Japan. Cold winds come from Siberia and they bring cold weather and snow to the north of Japan. The winds coming from the Pacific in the summer also bring typhoons and monsoon rains.
In order to determine the best time to visit Japan, I would divide the land of the rising sun into three sections: Southern, Central and Northern Japan. Southern Japan consists of the Kyushu region and the southwestern islands such as the Ryukyu Islands. The largest of the Ryukyu Islands in Okinawa. Southern Japan has an almost subtropical climate. Here you’ll find warm winters and hot summers. In the Autumn months, typhoons can often hit the shores of the country.
In the mild winter between January and February, the temperature can fall below the 20 degree Celsius mark. From the middle of January, you’ll begin to see the famous cherry blossoms. Central Japan is where you’ll find the largest island, Honshu. The climate in this area is very diverse. The central area reaches from the north with cool temperatures and right down to the south its humid subtropical temperatures. Due to the seismic activity on the island, earthquakes and volcanic eruptions are not uncommon and have already led to some disasters.
In northern Japan, you have the island of Hokkaido. Hokkaido has a short warm summer and long cold winters. You’ll find a lot of snow especially in winter which makes it a popular ski holiday destination. in the following articles, I’ll show the best times to visit the amazing country of Japan. You’ll find climate data for cities like Naha, Tokyo and Sapporo in the individual regions. Have fun!

If you decide to visit during the summer months, then you can expect temperatures of up to 26 degrees Celsius and seven hours of sunshine. During this time, it is worth exploring the eclectic natural landscapes of the island. For example, you can explore the area around Toya Lake, which is located in Shikotsu-Toya National Park.

Therefore if you want to get tickets and hotels you should definitely book early.
During the winter months theres a lot of snow in the North of Japan. For up to 17 days a month, the snow can envelop the landscape with a white blanket. The perfect weather for all of you winter sports enthusiasts. Pack your skis, snowboards and winter shoes and get ready for fun, but some tiring days during you Japanese holiday.
