Morinoyu West Onuma Hot Spring

The hot springs on the hotel grounds receive 270 liters of hot water per minute. These are “simple hot springs” that contain few natural chemicals and are kind to your skin. The clear, alkaline waters are said to be suited for relieving fatigue, nerve pain, and sore muscles. Additionally, the waters are also said to have an emulsification effect that gently exfoliates skin and removes excess oils, leaving it soft, smooth, and well-moisturized when you step out of the baths. What’s more, you can take in seasonal, picturesque views over the pond while you bathe in our open-air baths.
