Minamidaitō (南大東村, Minamidaitō-son) is a village located entirely on Minamidaitōjima in Shimajiri District, Okinawa Prefecture, Japan.

Minamidaitōjima is located approximately 360 kilometres (220 mi) east of Okinawa Island.

[1] In 1900, a team of pioneers from Hachijōjima, became the first human inhabitants of the island, and started the cultivation of sugar cane from 1903.

The village has no high school; students leave the island to complete their secondary education.

[10] In 2013, a motion picture called Leaving on the 15th Spring (旅立ちの島唄 - 十五の春, Tabidachi no shima uta - jūgo no haru) was released.

Themes include the relationship between inhabitants of Minamidaitō and Kitadaitō and families being torn apart because of the lack of a senior high school on the island.
