Best time to Visit

Good time to visit

Average time to visit

The best and most popular times to visit Japan are the climatically stable seasons of spring (March to May) and autumn (late September to November). The highlight of spring is the cherry-blossom season, which usually arrives in early April. Autumn is an equally good time to travel, with pleasant temperatures and soothing autumn colours, which usually peak between late October and mid-November. Of course, you can visit Japan anytime although the summer, from June to August, can be very hot and humid, and winter can be a little chilly for some people’s taste.
