April. Besides autumn, April is often considered the best time to visit Japan because the cherry blossom are in bloom and the weather is pleasantly mild.
When Is Typhoon Season? Typhoon season generally lasts from May to October, although typhoons may occasionally occur outside of this time period. In the south of Japan, Okinawa tends to experience more typhoons than the mainland. Northern regions of Japan such as Hokkaido tend to experience fewer typhoons.
Winter. Winter in Japan lasts from late December to mid-March with temperatures from 30 to 45 F (0 to 8 C). Winter is great for frugal travelers – if you avoid the holidays, winter is one of the cheapest times to visit Japan. After the holidays pass, mid-January to mid-March is also the least crowded time to visit.
In Aomori, Akita, and Iwate, snow begins to fall around mid-November, while in Yamagata, Miyagi, and Fukushima, it will start snowing in late November.
The best time to visit Japan is between March and May and between September and November as it's both warm and dry between these periods. However, the joys of springtime and the iconic blooming of the cherry blossoms in Japan are no secret, which means you'll be sharing the space with plenty of other travelers.
Any storms that do form in November tend to be weaker for the same reasons they are somewhat rare. As fall progresses, solar energy shifts from the Northern Hemisphere to the Southern Hemisphere and more northerly latitudes rapidly cool down, Trepanier explains.
