- Ryuodo Cave
Mysterious scenery in the Kotoura Caves
Just one among the rich variety of Kotoura caves, Ryuodo Cave is called "Sado's Blue Grotto," and is the largest lava rock cave on the island. Like the Blue Grotto in Italy, the sunlight creates a beautiful blue reflection and the waters glow brilliantly on days of mild weather and sea conditions. Sea kayak tours are available, providing participants with a chance to navigate into the cave and enjoy an otherworldly view.

Museums, Art Galleries and Resource Centres
Sado Island's Ogi Folk Museum, Sengokubune Exhibition Hall
Sado Island's Ogi Folk Museum is housed in the building of the former Shukunegi Elementary School. This museum exhibits a magnificent collection of over 30,000 folk materials including tools and equipment of fishery in South Sado and shipbuilders, as well as objects closely related to the everyday life of the common people which evoke the retro ambience of the Showa times (1926-1989). The ship on display was restored based on the design drawings of a sengokubune (wooden freight ship), which was built in 1858 in Shukunegi. The museum is adjacent to the Shukunegi village, a designated preservation area for important traditional buildings and architecture.
Shiawase Jizo Statue
Shiawase (happiness) Jizo, a statue of Jizo Bodhisattva (guardian of children), stands at 17.5 metres high including the base, and it is so huge that it can be seen from a distance. A villager revealed the great desire to build a Jizo statue in 1982, and it was completed in the following year. The white, elegant statue contrasts fabulously with the deep green at the foot of mountains in the Togami area. Past the Sanmon main gate, there is a hall of Jizo, where a variety of Jizo statues are installed. Just a short distance from the Jizo statue lies Iwayasan Cave.
