Now it is a secret getaway place in summer from the crowded city life. You can enjoy diving, scuba diving, surfing, etc. In addition to that, a natural blue cave is hidden and well-preserved in the south of the island. It has the name of Blue Grotto in Sado Island.

In the very south of Sado Island, Shukunegi is designated as Important Preservation Districts for Groups of Traditional Buildings. The town was prosperous from the end of the Edo Period to the beginning of Meiji-Period.

tub-turned boat

Before discovering the silver and gold mines, the city initially serves as a fishing port. Fishers rides on a tub-turned boat (Tarai-Bune) to catch fish, which becomes the symbol and heritage of Sado. The original design for a tub-turned boat is to go in the narrow cave to catch fish; therefore, the capacity of the boat is three people at most.

Local Experience Riding Tub-urned Boat to Blue Cave

ryuodo cave

Kotoura sea caves are right next to the Shukunegi area. Kotoura sea caves were formed through natural erosion process. The lower part of the rock was eroded by sea waves quickly than the upper side, and it creates a cave. There are about eleven different sea caves around the area. The biggest sea cave is called “Ryuodo” which means dragon king cave in Japanese. Ryuodo Cave is so beautiful that local people phrased it as Sado’s version of Blue Grotto.

A Mysterious Blue Grotto lies secretly around Sado island.

Ryuodo cave

When sunlight enters the sea, some of the light is absorbed by the sea, but it seems to reflect without absorbing blue or green color. Under a good weather condition, the sea ocean is transparent enough to see the seabed.

The best timing to visit Ryuodo cave is around 11 o'clock when the sunlight of the day enters deeply on the ocean. If all the condition is good (including weather, sunshine, and waves) you will be able to capture the stunning beautiful ocean blue.

They also provide the sea kayak tour to further explore in the cave. You can take your time exploring and observing the nature art by kayaking in Ryudo Cave.
