Geography
Minamidaitōjima is a relatively isolated coralline island, located approximately  south of Kitadaitōjima, the second largest island of the archipelago, and  from Naha, Okinawa. As with the other islands in the archipelago, Minamidaitōjima is an uplifted coral atoll with a steep coastal cliff of limestone (the former fringing coral reef of the island), and a depressed center (the former lagoon of the island). The island is roughly oval in shape, with a circumference of about , length of  and an area of . The highest point is  above sea level. The island contains several ponds in the interior, such as the Ōike-pond.

Climate
Minamidaitōjima has a tropical rainforest climate (Köppen climate classification Af) with hot summers and warm winters. Precipitation is significant throughout the year; the wettest month is June and the driest month is February. The island is subject to frequent typhoons.

History
It is uncertain when Minamidaitōjima was discovered. It is the most likely that their first sighting was by the Spanish navigator Bernardo de la Torre in 1543, in between 25 September and 2 October, during his abortive attempt to reach New Spain from the Philippines with the . It was then charted, together with Kitadaitōjima, as "The Two Sisters" (). There is little doubt that Minamidaitōjima and Kitadaitōjima were again sighted by the Spanish on 28 July 1587, by Pedro de Unamuno who named them the "Useless Islands" (). In 1788 the British captain John Meares named an island in the vicinity “Grampus Island”, but the recorded coordinates are not correct and it is not certain which of the Daitō island he sighted . The French also reported sighting an island in 1807. However, on 2 July 1820 the Russian vessel Borodino surveyed the two Daitō islands, and named the south as "South Borodino Island".

The island remained uninhabited until claimed by the Empire of Japan in 1885. In 1900, a team of pioneers from Hachijōjima, one of the Izu Islands located  south of Tokyo led by Tamaoki Han'emon (1838 – 1910), became the first human inhabitants of the island, and started the cultivation of sugar cane. The population reached 4000 in 1919. During this period until World War II, Minamidaitōjima was owned in its entirety by Dai Nippon Sugar (now Dai Nippon Meiji Sugar), which provided community services and subsidized pricing for its employees, and of whom were seasonal workers from Okinawa and Taiwan.

The island was garrisoned by the Japanese military in 1942. As the war situation worsened for Japan, many of the civilian inhabitants were evacuated to Okinawa, Kyushu or Hachijojima in 1944. The island was repeatedly bombed and shelled by the United States Navy from February to June 1945.

After World War II, the island was occupied by the United States, at which time its civilian population was 1426. The island was returned to Japan in 1972.
