Gyokusendo Cave

Gyokusendo Cave is located in Nanjo City, Okinawa Prefecture, and is the largest limestone cave in Okinawa, stretching approximately 5 km in length. The cave, which is believed to have been formed about 300,000 years ago, is home to more than 1 million stalactites, stalagmites, and stone pillars, making it the largest cave in Japan.\n\nThe temperature inside the cave is maintained at about 21°C throughout the year, making it cool in summer and warm in winter. Mysterious spots with spectacular views, such as the "Blue Spring," where illuminated stalactites reflect on the surface of the water, are scattered throughout the cave.\n\nAt the adjacent "Okinawa World," you can also enjoy the Ryukyu Village, Habu Hakubutsu Park, and Nanto Sake Brewery, allowing you to experience Okinawa's nature and culture throughout the day. Access is approximately 30 minutes by car from Naha City.
