Satsuma Province
Although Satsunan literally means the south of Satsuma Province, the north-eastern group of the Ōsumi Islands formed Tane Province for a brief period in the 8th and 9th centuries and then were merged into Ōsumi Province. The Tokara Islands and the northwestern group of the Ōsumi Islands belonged to Kawanabe District of Satsuma Province. The Amami Islands paid tribute to the Ryukyu Kingdom to the South until they were put under direct control in the late 16th century, but were conquered in 1609 by the Satsuma Domain.
