You'll be captivated by the sparkling emerald green water and the fantastical atmosphere, and the historic limestone cave will leave you feeling deeply at peace and empowered, both physically and mentally.

Reservations are also accepted on the day if there is availability! However, the meeting time varies each day due to the tide.
The only entrance is through the sea, and it is said that the Dragon Palace God resides there, making it one of the most powerful spots in Miyakojima. We are a certified shop affiliated with the Kayak Association, and we attend regular courses every year, so we can guide you safely.
Climb a large pumpkin-shaped stalactite, but the view from here is superb! The light shining from the entrance of the limestone cave makes the sea shine in emerald green, which is exactly the realm of God! Finally, you can dive from the stalactite to the sea while making a wish (only for those who wish).
We will take a memorable photo for you. We will provide you with unforgettable experiences and memories!
