About Kunashir

Kunashir is a volcanic island at the southern end of the Kuril chain, administered as part of Sakhalin Oblast in the Russian Federation and claimed by Japan. The island’s landscape is dominated by volcanic mountains, steep coasts and geothermal features.

Visitors and researchers are drawn to its volcanic topography, hot springs and coastal wildlife, though access is limited and subject to regional transport arrangements. The island forms part of a string of islands that separate the Sea of Okhotsk from the Pacific and has a mix of temperate forest and alpine vegetation.

The island has a complex modern history tied to Russo-Japanese relations and post-World War II border arrangements; fishing and limited settlement have characterised its recent economy. Infrastructure and services are concentrated in a few settlements along protected bays.

Geographically it lies immediately northeast of Hokkaido across the Nemuro Strait and south of the rest of the Kurils; the nearest major Japanese island is Hokkaido.

  • Sovereignty dispute: Part of the southern Kuril Islands chain, the island is administered by Russia but claimed by Japan, making it one of several disputed islands in the area.
  • Access and weather: The island’s volcanic terrain and frequent fogs mean access is seasonal and often limited to specific ports or charter services rather than regular ferries.

What to See#

  • Volcanic highlands: The island’s active and extinct volcanic peaks and calderas, which dominate its topography and include fumaroles, lava fields and steep slopes.
  • Coastal settlements: Coastal lowlands with fishing settlements and limited transport links to the Russian mainland and neighbouring Japanese islands.
