At the B course of the Submerged Cave in Tamura City, you can enjoy a great adventure walking underwater without any footholds. As you progress through narrow passages, you'll feel like an explorer, all while being surprised by the roaring sounds of the current. There's even a challenging spot called "Taifuku Gurui," but the sense of achievement upon clearing it is unparalleled. All you need to prepare are clothes to change into, lighting equipment, and sandals - that's it! Be sure to take on the challenge!
