Only Yu Hot Springs in Minamiashigarashi, Kanagawa is one of the best Hot Springs near Hakone. We rank it at #5 on our list.
I have surveyed many guests and they overwhelmingly love Only Yu. Only Yu is the only hot spring in Minamiashigarashi and it is nestled in a very romantic wooded setting. It is deep in the forest surrounded by nature, yet it is only a 5 minute taxi, bus or Only Yu courtesy van ride from Daiyuzan station in Minamiashigarashi’s Sekimoto area.

Only Yu Hot Spring
Only Yu offers: a restaurant, a cafe, a beauty salon, art displays and more. There is also good hiking in the forest around the hot spring.
