Hakone Koyongyuan Hot Spring Park, Japan's largest hot spring facility for round-trip on the same day. It consists of the soup of "YUNESSUN" Mori in the bathing area with a swimsuit and the soup of the naked bathing area "Seseragi no yu", and the soup of the sound of water that is only available here to enjoy food and shopping. "YUNESSUN" includes ancient Roman bathing beaches, Dead Sea baths, the Aegean Sea of the gods and so on. "Seseragi no yu" has the largest bathing area in Hakone, including 32 kinds of bathing beaches such as total baths, wooden barrel baths, garden-style open-air baths, etc. Looking at the Hakone Outer Route Mountain while taking a bath, don't have a taste.
