A Complex Post-War History
The history of Ōshima District in the mid-20th century is marked by significant political shifts. Following World War II, the region experienced a period of United States Army control. This occupation lasted from 1946 until the early 1950s, creating a period of administrative uncertainty for the local inhabitants.
The Amami Reversion Movement
During the U.S. military occupation (1946–1953), a powerful social and political movement emerged known as the Amami reversion movement. The primary goal was the "restoration of Ōshima District of Kagoshima Prefecture."
The movement was characterized by an overwhelming majority of the population—both on the islands and in mainland Japan—urging the immediate return of the islands to Japanese sovereignty. Notably, many participants sought to distinguish Amami from Okinawa. While the U.S. occupation forces occasionally referred to the area as "Northern Ryukyu," the reversion movement rejected this label. Instead, they used the name "Ōshima District, Kagoshima Prefecture" as a powerful symbol of their national identity and belonging to Japan.
