What is Inazumi Underwater Cave?

The Inazumi Underwater Cave in Bungo-Ono City, Oita Prefecture, was formed 300 million years ago during the Paleozoic era, and was submerged by the great eruption of Mount Aso 300,000 years ago, giving it its current shape.

• This is a rare underwater cavern in the world, where you can see many underwater stalactites, coral stones, bell holes, helictites, and more.

The temperature inside the cave is 16 degrees all year round, so you can enjoy sightseeing in a cool space in the summer and a warm space in the winter.
