Panoramic Open-Air Bath Unjo no Yu
TypeNatural Hot Spring
A roofless, liberating open-air bath with spectacular views, located on the mountainside of Mount Tsukuba at an elevation of 300 m. A 180-degree panorama with nothing to block the view spreads out before you, and on clear days you can see the beautiful silhouette of Mount Fuji and the Tokyo Skytree on the horizon, while at night you can look out over the sparkling nightscape of the academic city. The highly alkaline water, boasting a pH of 10.8, is extremely smooth and allows you to fully enjoy a "beauty bath" that removes old dead skin cells and leaves your skin silky smooth.
