Gyokusendo Cave within the Okinawa World complex in Nanjo City is one of Japan's longest stalactite caves, stretching approximately 5 km with 890 m open to visitors. Autumn is an ideal season to explore its constant 21°C interior, offering cool relief as outdoor temperatures ease into the pleasant subtropical autumn. The cave's dramatic stalactite and stalagmite formations have been forming for 300,000 years, and the surrounding Okinawa World grounds showcase Ryukyuan village culture alongside the cave experience.
