Hokkaido (help·info)(北海道,Hokkaidō?, literally "Northern Sea Circuit"), formerly known as Ezo, Yezo, Yeso, or Yesso, is Japan's second largest island; it is also the largest and northernmost of Japan's 47 prefectures. The Tsugaru Strait separates Hokkaido from Honshu, although the two islands are connected by the underwater railway Seikan Tunnel. The largest city on Hokkaido is its capital, Sapporo, which is also its only ordinance-designated city.
Shiretoko National Park(知床国立公園,Shiretoko Kokuritsu Kōen?) covers most of the Shiretoko Peninsula at the northeastern tip of the island of Hokkaidō, Japan. The word "Shiretoko" is derived form an Ainu word "sir etok", meaning "end of the Earth".
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 Japan. The park has a hot springs waterfall called Kamuiwakka Falls(カムイワッカの滝,Kamuiwakka-no-taki?). Kamui wakka means "water of the gods" in Ainu.
The forests of the park are temperate and subalpinemixed forests; the main treespecies include Sakhalin fir (Abies sachalinensis), Erman's birch (Betula ermanii) and Mongolian oak (Quercus mongolica). Beyond the forest limit there are impenetrable Siberian Dwarf Pine (Pinus pumila) thickets.
