The large island of Hokkaido is joined to the north of Honshu by the Tsugaru Strait. While some of its natural landscape is given over to agriculture, it also encompasses forest and, in the centre, the high mountains which enabled the island's capital, Sapporo, to host the 1972 Winter Olympics. Boasting six national parks, Hokkaido has now turned to green - and white - tourism, and finally acknowledged the Ainu, the island's indigenous people who were colonised during the Meiji period. A replica Ainu village can be seen in the Shiraoi Ainu Museum in Shikotsu-Toya National Park.
