This is one of the oldest hot springs in Japan, first mentioned in records from the Edo Period! The current building dates from the 1880s. Just a five minute walk from Arima Station, Kin no Yu offers a high-saline, iron-rich “golden waters” spring, sure to relieve any aches and pains you may have, and leave you feeling relaxed and fresh.
Be sure to bring a towel along. If you like to do more than one onsen in a day (and who doesn’t), a combo ticket for Kin no Yu and Gin no Yu is ¥850, and if you tack on a visit to the nearby Taiko-no-Yu Museum, it’s ¥1,000.
