Sapporo is the capital and largest city of the northern island of Hokkaido. One of Japan's newest and nicest cities, it has little in the way of traditional architecture. But what it lacks in "Japanese-ness" it makes up for with its lovely open, tree-filled boulevards to enjoy in summer and excellent snow (and facilities to cope with said snow) in the long winter.
Sapporo has four distinct seasons. Temperatures are generally cool and pleasant in a summer, making it a popular place to escape the heat that grips much of the rest of Japan. Winters are harsh by Japanese standards, though not as harsh as the likes of Harbin or Chicago.
Sapporo is one of the snowiest cities in the world (about 6 meters snowfall each year, three times as much as in Montreal), and the city makes full use of this by hosting the world-renowned Sapporo Snow Festival in February every year.
