Hashiri-yu (Running Bath)

Suzuriyu, located in Mt. Izu, Atami City, is a historic hot spring known as one of Japan's three major ancient springs. Discovered about 1,300 years ago, this hot spring is a horizontal hole type that is rare in Japan, with 170 liters of hot water flowing out from the back of the cave, at about 70 degrees Celsius per minute. The name comes from the way the hot water that gushed out from the mountains runs down to the coast. You can freely tour the cave and experience the mysterious atmosphere of steam and heat. There is also a free foot bath nearby, so you can stop by in between sightseeing and have a relaxing moment. (Photo by AC)
