Shokanbetsu-Teuri-Yagishiri Quasi-National Park is a protected area on the island of Hokkaido in northern Japan, encompassing coastal headlands, offshore islands, and mountainous terrain. The park includes the islands of Teuri Island and Yagishiri Island as well as the Shokanbetsu Mountains, and was designated a Quasi-National Park in 1964. It is administered under Japan's system of protected areas and managed with input from local municipalities such as Haboro, Shosanbetsu, and Tobetsu.
The park covers approximately 190.09 square kilometres and brings together features of the Sea of Japan coast, island ecosystems, and alpine environments in a single protected framework. Its establishment reflects postwar expansion of Japan's protected-area network under the influence of the Ministry of the Environment (Japan) and conservationists responding to pressures from fishing, forestry, and tourism. The park is recognized for migratory seabird colonies, remnant cool-temperate forests, and the distinctive topography of the Shokanbetsu Mountains range.
The park spans coastal zones along the Sea of Japan and the northwestern shore of Hokkaido, including two offshore islands, Teuri Island and Yagishiri Island. The Shokanbetsu range, part of the park, includes peaks that are geologically related to the orogenic processes affecting northeastern Asia and the Japanese archipelago. Bedrock comprises volcanic and sedimentary sequences related to the island arc systems of Honshu and Hokkaido, and glacial and marine terraces record Pleistocene sea-level fluctuations known from studies in Sakhalin and the Kuril Islands. Coastal cliffs, headlands, and sheltered bays create diverse microhabitats used by species shared with regions such as Okhotsk, Toya, and Sapporo environs.
Vegetation mosaics range from boreal-coniferous and cool-temperate broadleaf forests to coastal shrublands and offshore island heath. Dominant plant formations include stands comparable to those in Ainu National Park regions and communities analogous to those on Rishiri and Rebun. The islands are notable seabird breeding grounds for species that migrate along the East Asian–Australasian Flyway, attracting species parallel to those documented on Hokkaido's Notsuke Peninsula and Cape Erimo. Fauna includes marine mammals recorded around Hokkaido waters, seabirds with affinities to colonies on Samani and Shakotan, and terrestrial birds and insects linked to the biogeographic history of the Japanese islands. Plant species include endemics and boreal relics similar to those protected in Shiretoko and Daisetsuzan National Park.
Human use of the area spans indigenous habitation by the Ainu people, historical incorporation into the domains of officials during the Meiji era, and development tied to fisheries and coastal communities such as Haboro. The islands' names and place-names reflect Ainu and Japanese linguistic heritage, and the park contains cultural heritage sites associated with traditional fishing, boatbuilding, and seasonal migratory patterns linked to broader networks including Otaru and Wakkanai. Postwar conservation dialogues that led to the park's designation involved prefectural authorities in Hokkaido Prefecture and national agencies linked to the environmental policies that emerged from the 1960s environmental movement in Japan.
Management responsibility falls under frameworks administered by the Ministry of the Environment (Japan) with coordination from Hokkaido Prefecture and local municipalities. Conservation priorities include protection of seabird colonies, preservation of island forest communities, and mitigation of invasive species pressures documented in other Japanese island reserves such as Okunoshima and Yashiro Island. The park participates in regional biodiversity monitoring initiatives analogous to programs run in Shiretoko and collaborates with research institutions and NGOs active in northern Japan conservation and avian studies.
Visitors come for birdwatching, hiking in the Shokanbetsu Mountains, coastal scenery, and seasonal marine viewing. Recreational infrastructure mirrors facilities found in other Hokkaido protected areas like Daisetsuzan National Park, with trails, observation points, and local visitor centers in towns such as Haboro. Activities connect to regional tourism circuits that include Sapporo, Otaru, and the wider Sea of Japan coast, and ecotourism operators emphasize low-impact interpretation similar to guides working in Rishiri-Rebun-Sarobetsu National Park.
Access to the park is provided via road networks from urban centers including Sapporo and ferry services from ports such as Haboro to Teuri Island and Yagishiri Island. Seasonal ferry timetables resemble those serving other island destinations like Rishiri and Rebun, and land access to mountain trails is commonly staged from towns that are connected to the Hokkaido Expressway corridor and regional rail services linking to stations in Asahikawa and Wakkanai.
