Japan has four seasons, which generally correspond with those in North America. Summer, from June through August, is the most popular time for travelers to head to the Asian island. While summer can be quite rainy in some parts of the country, it's the best season during which to enjoy balmy temperatures in Japan. In autumn, trees across the country display spectacular colors. During winter, Japan sees colder days, shorter temperatures and fewer tourists. Spring is the best time to visit Japan if you want to see those iconic Japanese cherry blossom trees in full bloom.
