The Japanese name for the island, Suishō, is of Ainu origin. In the 1834  or Village Registers of the Tenpō Era, Suishō is listed as a settlement of Nemoro. Visited by Matsuura Takeshirō and written about in his diaries, in the early Meiji period the island formed part of the village of Goyōmai [ja], later merged into Habomai. Before the Pacific War, most of the population were involved in the fishing industry; they were joined by migrant workers from the area of Niigata Prefecture and Toyama Prefecture each spring. Konbu (kelp) was the most important product, and there was also canning of salmon, trout, crabs, and shrimp. At the end of the war, the population stood at 986, in 154 households, along with 325 horses. Currently, the Habomai Islands as a whole are uninhabited, other than the stationing of Russian guards.
