Japan plans to purchase an uninhabited Kagoshima Prefecture island for potential use for U.S. military aircraft carrier landing practice, a government source has said.

The government wants to purchase Mage Island, which is administered by the city of Nishinoomote, for training exercises, including those involving the Osprey tilt-rotor transport aircraft currently deployed to a U.S. Marine base in Okinawa, the source revealed Friday.

Mage is also a candidate for the location of a Self-Defense Force base that will be involved in disaster preparedness.
