Karafuto Prefecture
In addition, in 1907 Japan formed Karafuto Prefecture to govern the island of Sakhalin. Karafuto was divided into four subprefectures: Toyohara (in present-day Yuzhno-Sakhalinsk), Maoka (in present-day Kholmsk), Esutoru (in present-day Uglegorsk) and Shikuka (in present-day Makarov).
