Dive into a transparent underwater world just for you, and experience the blue light's wonder, found only in the Okinawan sea.

Entry Method Tailored to Your Preference
Choose between beach entry, where you gradually get acquainted with the water while standing in shallow waters before heading to the cave, or boat entry, where you comfortably reach the dive spot in just 5 minutes from the port. If you want to reduce physical strain or are traveling with children or parents, the boat plan is recommended.

Enter the natural cave created by nature and admire the blue waves shimmering as sunlight reflects. Observe the mystical scenery inside and outside the cave through snorkeling or discovery scuba diving.
