Daikoku Island (大黒島 Daikoku-jima) is an uninhabited island in Akkeshi, Hokkaidō, Japan. Together with the smaller island of Kojima (小島) to the north, it forms a natural breakwater at the entrance to Akkeshi Bay (厚岸湾).[3] The island forms part of Akkeshi Prefectural Natural Park and its entire area of 107 hectares is a Special Wildlife Protection Area.[1][4] It provides an important breeding ground for seabirds, in particular several hundred thousand Leach's storm petrel,[2] as well as the tufted puffin, Japanese cormorant, pelagic cormorant, spectacled guillemot, slaty-backed gull, and rhinoceros auklet.[2][5][3] Twelve hectares of the breeding grounds have been designated a Natural Monument.[5]

Also found on the island are the grey-sided vole and harbour seal.[2][6] Trees include the green alder, painted maple, and Erman's birch; other plants, Sakhalin knotweed and Parasenecio hastatus.[2] At the southwest tip of the island at an elevation of approximately 105 metres is Akkeshi Lighthouse (厚岸灯台), which began operations on 25 November 1890.[3][7] Of the island's 107 hectares, 64 are owned by the state, 42 by the municipality, and 1 is in private hands.[2]
