About
Shiroyama Onsen, located on a hill in Kokubu, Kirishima City, serves as the large bath of City Hotel Inn Kokubu. It is a natural onsen with a sodium chloride bicarbonate spring sourced from 1200 meters underground, rich in salt and iron, giving the water a golden color. The bathhouse features a calm Japanese-style interior and includes a sauna, cold bath, electric bath, lockers with keys, massage machines, and a coin laundry. The cold bath uses Tsutsunokuchi famous water, which is also used throughout the hotel for drinking and daily use. Parking is available for 60 cars.
