Between 1905 and 1945, the Japanese Empire administered the southern half of Sakhalin, using the name Karafuto (樺太). The area was designated a chō (廳), the same term given to Hokkaidō at the time. It is commonly referred to as Karafuto Prefecture in English. The prefecture was divided into 4 subprefectures (支廳, shichō), which in turn were subdivided into 11 districts, in turn divided into 41 municipalities (1 city, 13 towns, and 27 villages)
Some municipalities had multiple possible readings. 敷香, for instance, was read Shikuka, Shisuka, or Shikika, depending on sources.
All Kanji names are in Shinjitai, a modern form which was not used when the prefecture existed. The Kyūjitai names used when the prefecture existed are listed in parentheses.
The list shows the current Russian names in parentheses. However, Russian divisions do not match with Japanese divisions. These names just roughly overlap with central towns.
