Aoshima Island (Miyazaki City, Miyazaki Prefecture) is a small island with a circumference of only 1.5 km. It is surrounded by a rock formation, created by the crashing waves, known as Oni-no-Sentakuiwa (the ogre's washboard). It is one of the representative scenic spots in the prefecture.

The island is the treasure trove of plants that are rare in Japan. Over 5,000 Chinese fan palm trees and over 20 species of sub-tropical plants naturally grow on the island.

Aoshima Shrine on the island is said to have been founded 1,200 years ago. Surrounded with Chinese fan palms, you will feel as if you were offering a prayer in a jungle.

From early July to the end of August, the beach is crowded with people, who enjoy swimming as well as viewing endless blue water against clear sky.
