Onna Beaches

Apogama Beach(Mermaid’s Grotto) is located in Onna Village in the northern part of the main island of Okinawa.

There are many resort areas in Okinawa such as “Cape Manzamo” and “Manza Beach”.

The characteristic of Apogama Beach is “Natural Cave Apogama”.
In the Okinawan dialect, it means “gama = cave”.

The area around Apogama Beach was owned by the U.S. military until about 25 years ago.
So this place has not been developed as a resort.
*Now it is already returned

It is also a popular spot for diving and snorkeling, and when I went to Apogama, there were several people diving and snorkeling.
