One of the most remote regions in all of Japan, much of the peninsula is only accessible on foot or by boat. The park is best known as the home of Japan's largest brown bear population and for offering views of the disputed Kunashiri Island, claimed by Russia. The park has a hot springs waterfall called Kamuiwakka Falls. Kamui wakka means "water of the gods" in Ainu.
The forests of the park are temperate and subalpine mixed forests; the main tree species include Sakhalin fir, Erman's birch and Mongolian oak. Beyond the forest limit there are impenetrable Siberian Dwarf Pine thickets.
In 2005, UNESCO designated the area a World Heritage Site, advising to develop the property jointly with Kuril Islands of Russia as a transboundary "World Heritage Peace Park"." - in: wikipedia
