found the hot spring in 788, and named it Yakushiyu (Hot spring
of Yakushi). That was the beginning of Yumoto Hot Spa. Also, he
named the mountain on the back as Yusengatake (Mountain of hot spring),
and enshrined Yakushi Rurikou Nyorai on the top of the mountain.
Moreover, Saint Kobo visited there in 820, and found Kanjizaiyu
(Hot spring of Kanjizai), and enshrined Kanzeon Bosatsu.
As noted above, there have been 9 hot springs including
Yakushiyu, Kanjizaiyu and Kawarayu. Those hot springs have been
managed as public bath. Unfortunately, those public bathes are no
longer existing, but hotels and inns pull the hot spring into their

the spring is located in Yunodaira Marshland. You can see that the
hot spring is coming out to the ground. That hot spring has an effect
