Daisetsuzan (also called Taisetsuzan) National Park is located in the mountainous center of the northern Japanese island of Hokkaidō. At 2267.64 square kilometers, Daisetsuzan is the largest national park in Japan. The Japanese name means "great snowy mountains," and it is often called "the roof of Hokkaido." But the name the indigenous Ainu gave these mountains is "the playground of the gods."
