Shiretoko
An ecosystem thriving on sea ice and a paradise for diverse wildlife
Protruding into the sea from the northeastern tip of Hokkaido, the Shiretoko Peninsula is a slender peninsula that measures approximately 70 kilometers in length and 25 kilometers across at its widest part. The Shiretoko mountain range, which contains active volcanoes such as Mount Rausu and Mount Io, stretches from north to south at the peninsula's center. It is also known for being the place at the lowest latitude in the world where sea ice approaches the shore. Plankton that blooms on the sea ice is the basis for a food chain that connects creatures of the land and sea, forming a rich ecosystem. The name Shiretoko is derived from sir etok, meaning “the end of the earth” in the Ainu language. As this name would suggest, the Shiretoko Peninsula is a pristine region beyond the reach of human exploitation or development where you can come into contact with thriving plants and animals of the sea, mountains, and beaches.
