Okinawa Tunchi: The Mysterious Pond with Mermaid Legends.

Tunchi is a national scenic spot and natural monument. From above, the two ponds of similar size resemble a pair of eyes, hence they are also known as the Dragon's Eyes. The cobalt blue waters of Tunchi are separated by a natural stone bridge. In fact, the ponds are connected underwater, and the one closer to the sea is also connected to the open sea. The name Tunchi comes from this connection. Visitors can enjoy a leisurely walk along the pondside trail to appreciate the scenery. To truly see this rare geographical feature, one must dive into the water to explore and experience its unique charm. However, caution is advised as the pond is about 50 meters deep and the journey involves passing through a dark underwater tunnel, which can be quite challenging for novice divers. Why has Tunchi become a diving hotspot? The unique topography is certainly a highlight, but the area is also where freshwater and seawater meet, creating a thermocline phenomenon that forms a unique natural landscape. Of course, the mysterious Tunchi has been associated with mermaid legends since ancient times. It is said that after a mermaid was captured by a fisherman, the King of the Sea, in a rage, caused a tsunami that formed Tunchi. It is unknown whether divers come here with the hope of seeing mermaids.
