Japan's Annual Climate
March to May and September to November are great times to visit Japan, however can be very busy at these times of year. You will witness the beautiful cherry blossoms or bright red leaves adding contrast to the scenery.
June to August is usually very hot and humid however the mountains of the Japanese Alps and Hokkaido’s wild national parks are the perfect time of year to visit for hikers and outdoor enthusiasts. Rainy season occurs from the end of May until the middle of June or July.
For a very different experience, head to the north of Japan in winter from December to February where you'll experience the snow but festivals and events are aplenty.
Please note that Japan’s national holidays into account, too. Shogatsu (Japanese New Year), Obon (in mid-August or mid-July, depending on the area), and the Golden Week (between April 29 and May 5) are busy times for residents.
