Tatamigaura is a designated national monument. After exiting the cave, visitors will find a vast flat rocky area, the Senjyogaura. It is also dotted with rounded, protruding rocks, creating a mysterious landscape that looks like a fantasy world against the sea.
At Tatamigaura, the strata of the seabed from 16 million years ago can be seen, and fossils of whales and shells can be observed on the rocks. Recently, it has become a popular power spot for love, and visitors are invited to experience the magnitude of the world of sky and sea, while feeling their way back to ancient times.
