Straight from the well hot spring water fills the tubs here at this mildly out of the way almost-supersento. Ebisu-Yu is right on the border of being a real supersento but not big enough to qualify in my mind.
A large well designed rotenburo made of rock and surrounded by a garden serves as the centerpiece. The spring water is fantastic. The two baths are different and change everyday.
Sadly, I don't believe there's good bus service here from Hanshin Amagasaki so get ready for a longish walk to get there and back.

Second photo is a sign that says the following:
"This bath is
not heated
not diluted
not recycled
100% hot spring fed into the baths
Don't worry about bathing here
