Shiretoko: a peninsula linking sea, land and livelihoods

Volcanic mountains, cliffs, lakes and forests form varied land habitats. Rivers carry water to coastal seas, while salmon return from the sea to rivers to spawn. Bears and birds feed on the fish, transferring marine nutrients into land ecosystems. These movements connect the peninsula’s forests, rivers and coastal food webs.

Sea ice forms when seawater freezes; ice carried by winds and currents is called drift ice. Freezing promotes circulation that brings nutrients from deeper water towards the surface. Microscopic plant-like organisms grow beneath the ice and multiply as it melts. Zooplankton feed on them, supporting fish, marine mammals and birds. Salmon returning to rivers extend those connections onto land. Ice arrival, extent and duration vary from year to year.

Life and work by the sea

Ainu livelihoods and trade preceded merchant-run fisheries. Under the contracting system, merchants imposed coercive labour and unequal exchange. The area came under the Shari contracting district in 1790; the system was formally abolished in 1869. Modern fisheries and settlements continued to shape the peninsula alongside later conservation initiatives.

Settlement and conservation at Iwaobetsu

Modern agricultural settlement in Iwaobetsu began in 1914–1915 and continued through later settlement schemes. Stony ground, water shortages and poor access hindered farming. Families increasingly left from the 1960s; the last farm closed in 1973. Property speculation then threatened the abandoned land. The later conservation campaign therefore concerned former farmland as well as the forest it hoped to restore.

A local movement to purchase land

Shiretoko became a national park in 1964. In 1977, Shari launched the 100 Square Metres Movement, raising donations to buy abandoned farmland threatened by development and restore its forest.

Logging disputes and a change of policy

Conservation faced conflict as well as progress. A national-forest logging plan provoked opposition in 1987, yet some cutting took place that spring beside the forest being restored. The subsequent plan was withdrawn. In 1990, national forest in Shiretoko, including the proposed logging area, received forest-ecosystem protection.

Forest restoration and different boundaries

The movement shifted towards forest and ecosystem restoration in 1997 and completed its target-land acquisition in 2010. The World Heritage property, inscribed in 2005, covers about 71,100 hectares of land and sea. Movement land, heritage property and the peninsula have different boundaries.
