Yobizuru Hot Spring

Developed in 1952, the area of Yobizuru Hot Spring has been known as "Yuden" from long ago.
Boasting one of the highest radium contents in the world, it is a colorless, transparent, tasteless, odorless, and weakly alkaline hot spring.
Yamaguchi Prefecture issued a drinking permit for the water, and many guests recovering from injuries visit the hot spring seeking the water.
