Sea breezes and a pH 9.4 beauty spring at Aoshima
Shinwa-no-Yu is the bath of a hostel and spa close to Aoshima's shore, and day visitors are welcome. The water is an alkaline simple sulfur cold mineral spring at a high pH 9.4, called a beauty spring for its silky feel. Besides the great bath there are a free-flowing open-air bath, a cold plunge drawn straight from the source, a dry sauna and two private baths. A large painting of Mount Fuji by a Miyazaki artist covers the great-bath wall, to be viewed from the water.
Hours and tips
Open from 6:00 in the morning to 22:00 at night, with last entry at 21:30. Since the ticket is valid all day, you can bathe in the morning, walk to Aoshima Shrine and the shore, and return in the evening. Private baths stop at 20:00 and need booking, so reserve early if you want one. Note only that guests with tattoos cannot bathe.
Before you go
