Yajia Cave

Yajia Cave (Yajia-gama) is a huge semi-natural cave approximately 800meters long. This ancient cave has existed in Okinawa for tens of thousands of years. Why are there so many human bones in this cave? Yajia-gama is a home for creatures and sprits of island’ s ancestors.

In this cave, you can see many stalactites worth 20,000 to 40,000 years.
Yajia-gama is a place of burial. In burial, the body of a deceased person is placed here and eaten by creatures in the natural world such as birds and coconut crabs. A few years later, when only the bone remains, the family wash and bury the bone. It is called “Senkotsu” (bone wash) which is an old Okinawan custom with respect for the deceased and sprits. This was the grave of the people who lived around here. This custom was held until the late 1960s, and the last official record is Kudaka Island. In addition, the cave was used as an air raid shelter during the world warII.

There are no artificial lights in the cave. It is completely dark.
