Nakanoshima has been populated for several thousand years. The island was once part of the
Ryukyu Kingdom. During the
Edo period, Nakanoshima was part of
Satsuma Domain and was administered as part of
Kawabe District. In 1896, the island was transferred to the administrative control of
Ōshima District, Kagoshima, and from 1911 was administered as part of the village of
Toshima, Kagoshima. From 1946-1952, the island was administered by the
United States as part of the Provisional Government of Northern Ryukyu Islands. Until 1956, the village hall for Toshima Village was located on Nakanoshima. It was then relocated to within the city of
Kagoshima. In early 1950, a small herd of wild horses in the south of the island were identified as a distinct breed, named the
Tokara pony. This species only occurs on Nakanoshima and is believed to have been brought to the island around 1890 from
Kikaijima, an island near
Amami Ōshima. After
World War II, the species almost became extinct, and survivors were removed to a ranch operated by
Kagoshima University on mainland Kagoshima for protection. Today, some have been reintroduced to Nakanoshima. ==Notes==
