Japan has a diverse climate, with four distinct seasons. The best time to visit Japan depends on what kind of weather and activities you prefer.
Spring (March to May)
Spring is the best time to visit Japan for cherry blossoms. The cherry blossom season starts in southern Japan in late March and moves northwards, reaching Tokyo and Kyoto in early April. The weather is mild and comfortable, making it ideal for sightseeing.
Summer (June to August)
Summer is the peak tourist season in Japan, with hot and humid weather. It is a good time to visit the beach and participate in outdoor activities, but it can be uncomfortable for sightseeing in the big cities.
Autumn (September to November)
Autumn is the second-best season for tourism in Japan, with comfortable temperatures and beautiful fall foliage. The leaves change color starting in northern Japan in September and moving southwards, reaching Kyoto and Tokyo in late November. It's a great time for hiking and viewing the changing leaves.
Winter (December to February)
Winter in Japan can be cold and snowy, especially in the northern areas. It's a good time to visit the ski resorts, but it can be difficult for sightseeing and outdoor activities. The exception is the region of Kyoto and Tokyo where the winter weather is relatively mild.
Overall, the best time to visit Japan depends on your interests and what you want to see and do. If you are looking for cherry blossoms or autumn foliage, spring or autumn would be the best time to visit. If you prefer hot weather and beach activities, summer would be the best time, but if you want to experience skiing and other winter activities, winter would be the best time.
