History
The area of Minamiōsumi was part of ancient Ōsumi Province. Remains from the Jomon and Yayoi Period have been found within town borders. During the Heian period it was the site of a large shōen landed estate ruled by the Neshin clan into the Sengoku period. Konene Port was active in this period with Nanban trade with Portuguese merchants and with trade to Ryukyu and Southeast Asia. During the Edo Period, the area was part of the holdings of Satsuma Domain. The villages of Sata and Konejime were established on May 1, 1889, with the creation of the modern municipalities system. The village of Nejime became the town of Nejime on January 1, 1941. The village of Sata became the town of Sata on September 1, 1947. Nejime and Sata were merged to become Minamiōsumi on March 31, 2005.[4] The town name was chosen from among ideas submitted by the public.
