Hokkaido is great in February when the yearly Snow Festival is held, in early May when the cherry blossoms bloom or from September when the autumn colors are extremely beautiful. In winter Hokkaido is one of the best places for all kinds of winter sports. Yet summer is probably the most popular season for Japanese people to visit Hokkaido. Itâs the prefecture with the mildest climate in summer. Itâs not as hot and humid and it cools down at night. Furthermore, Hokkaido offers beautiful nature and flower fields which are best explored in summer.
