Hashiriyu is a horizontal-style hot spring, which is rare in Japan and is one of the three major old springs in Japan, discovered over 1300 years ago.

The name “Hashiri-yu” derives from the fact that the hot water springs from the mountains and runs down to the coast.

Even now, 7,000 tons of hot water at the temperature of 70 degrees Celcius is gushing out from the cave with a depth of 5m, and you can see a mysterious sight.
