Hokkaido is the northernmost of Japan's four main islands. Hokkaido continues to represent the untamed wilderness with many great national parks. For many visitors
the scenery resembles northern Europe, with rice paddies and concrete warrens typical of the rest of Japan replaced by rolling fields and faux-German cottages.
However, the ubiquitous hotspring resorts in much of the island serve as a reminder that you are still in Japan.
Hokkaido is by far Japan's largest prefecture, consisting of Japan's entire northern island and its surrounding islets. Hokkaido is cooler than the rest of Japan, and
the merciful lack of Japan's muggy summers and rainy season makes it a very popular domestic destination between May and August.
Some of Hokkaido's inland areas have a continental climate, with large daily and yearly temperature variation. - Source : Wikitravel
