What is the climate like in Japan? Japan has four distinct seasons.
However, the spring and the fall are generally short-lived compared to the extreme heat and cold of summer and winter, respectively. Spring is a great time to engage in outdoor sports without worrying about the heat. Japanese spring ranges from March to May. Summer in Japan lasts from early June to early September. Most days are very hot, and very humid and sticky. Fall is very nice in Japan. Like spring, fall is quite short-lived, running roughly from September to November. Fall is arguably the best time of year to go hiking or engage in other outdoor sports. In fall you can enjoy a very comfortable temperature in the daytime although it can get quite cool at night. Japanese winters are very dry and clear. Winters in Japan are cold and long, probably more so than what you’re used to (…unless you’re from Canada).
