The water that comes out of the faucets in the guest rooms is delicious natural groundwater.

The Kussharo Caldera is blessed with abundant water resources. We bring you natural groundwater—which has stored the earth’s bounty over the course of many years—straight from the faucet in your room.
All water used throughout the hotel comes from this groundwater. A gift from nature that brings people together through its delicious taste. Be sure to fill your reusable bottle with chilled water before heading out!
