About Gyokusendo Cave

A Natural Marvel Situated in the Center of Okinawa is the Gyokusendo Cave.

Gyokusendo Cave is a breathtaking natural wonder that has been mesmerizing tourists to Okinawa Island, Japan, for many years. It is located in the southwestern section of the island. The limestone cave was formed more than 300,000 years ago, and it features a labyrinthine network of stalactites, stalagmites, and underground rivers that flow through its walls. Additionally, the cave is known for its crystal clear waters. Gyokusendo Cave is an attraction that visitors to Okinawa simply cannot miss due to the unearthly beauty of its interior as well as its extensive geological history.

The name of the cave in Japanese is Gyokusendo, which literally translates to “cave of the valuable stone route.” It is said to be one of the longest caverns in Okinawa, reaching for more than 5 kilometers underground, making it one of the longest caves on the island. Nevertheless, only a small section of the cave, which is approximately 850 meters in length, is accessible to the general public. Cave goers have the opportunity to marvel at the complex rock and mineral formations that line the cave’s walls and ceilings as they make their way through the cave’s meandering passageways.

The steady drop of water over the course of millennia has resulted in the formation of stalactites and stalagmites in Gyokusendo Cave, which are one of the cave’s most distinctive characteristics. There are some of these formations that are over 30 meters long and take on a broad variety of colors and patterns, ranging from delicate wisps to gigantic pillars. Some of these formations are even multicolored. The cave’s underground rivers are equally as spectacular, with water so clean that it mirrors the cave’s one-of-a-kind beauty and serves as a habitat for a wide variety of fish and other forms of aquatic life.

In addition to its breathtaking natural features, Gyokusendo Cave is also home to a museum that details the geological history of the cave as well as the one-of-a-kind ecology that has developed within its confines. There are displays at the museum that explain how limestone caves were formed, the history of Gyokusendo Cave, as well as the plants and animals that live in the cave’s underground rivers and ponds.
