An inn where you can enjoy a famous 100% free-flowing source spring and a nationally rare cold iron spring cold bath
Ishikawa Komatsu City
"Komatsu Green Hotel" is a hot spring hotel in Komatsu City, Ishikawa Prefecture. Ideally located just off the Komatsu Interchange, it offers a superb natural hot spring drawn from water that springs from the grounds, enjoyed in the large public bath as 100% free-flowing source water with no added water or heating whatsoever. Right next to the sauna is a free-flowing cold bath fed by the nationally rare "cold iron spring," which is exceptionally rich in iron. Despite being sharply cold, the more you soak, the more warmth and vitality you feel welling up. In addition, the property’s ten unique private family baths, known as "Jūyū Monogatari," are extremely popular. They include open-air reclining baths and rooms with private saunas and cold baths, and all rooms are barrier-free.
