  Rishiri Island (利尻島, Rishiri-tō) is a volcanic island in the Sea of Japan off the coast of Hokkaido, Japan. Administratively the island is part of Hokkaido Prefecture, and is divided between two towns, Rishiri and Rishirifuji. The island is formed by the cone-shaped extinct volcanic peak of Mount Rishiri. Along with Rebun Island and the coastal area of the Sarobetsu Plain, Rishiri forms the Rishiri-Rebun-Sarobetsu National Park. The main industries of Rishiri are tourism and fishing. The island is about 63 kilometres (39 mi) in circumference and covers 183 square kilometres (71 sq mi). The island has a population of 5,102 residents.
  
  ## Etymology
  
  Rishiri derives its name from the Ainu language, and means "high island", or "island with a high peak", a reference to the altitude of Mount Rishiri above sea level.
  
  ## Geography
  
  Rishiri Island is located roughly 20 kilometres (12 mi) west of Hokkaido; Rebun Island is a further 10 kilometres (6.2 mi) to the northwest. Rishiri is roughly circular with a coastline of 63 kilometres (39 mi). The island spans 19 kilometres (12 mi) from north to south and 14 kilometres (8.7 mi) from east to west. Mount Rishiri rises to an altitude of 1,721 metres (5,646 ft) and provides a good source of fresh water; numerous small ponds and springs are located at the foot of the mountain. The residents of Rishiri live in coastal communities, which are connected by a bus service that circumnavigates the island.
  
  ### Important Bird Area
  
  The island has been recognised as an Important Bird Area (IBA) by BirdLife International because it supports populations of black-tailed gulls and Japanese robins.
