Oki Daitō Island

Oki Daitō is an uninhabited coral island in the Pacific Ocean that belongs to Okinawa Prefecture in Japan. The triangular surface is surrounded by steep limestone cliffs rising from the sea to heights of about 31 meters, while the terrain appears barren and rocky throughout.

A Spanish navigator charted the island in 1543 during a voyage eastward from the Philippine archipelago. Mining operations began later and ended with evacuation during the World War, since then the island has remained empty of people.

Visitors experience the silence of a place whose former name Rasa reflects a time as a mining outpost. Phosphate extraction once shaped the rhythm of daily life for families who departed after the conflict ended.

Rasa Industries owns the land and permits access only with express authorization. Military training takes place on the grounds, so contacting them before any visit is essential.

Defense forces use the remote terrain for maneuvers, giving the island a military function far from inhabited shores. The distance to Minamidaitōjima exceeds 100 kilometers, making the isolation remarkable.
