Nagano Karuizawa Town
A luxury resort that delivers state of perfect relaxation with a renowned spring from Kita-Karuizawa and two kinds of saunas
GLAMDAY STYLE HOTEL & RESORT KYU-KARUIZAWA is a luxury hotel condominium in Karuizawa Town, Nagano Prefecture. The guest-only public bath is filled with abundant natural hot spring water brought in from Oku-Kusatsu Onsen Kakurenoyu, a renowned spring in Kita-Karuizawa, offering exceptional relaxation. Embraced by the warmth of wood, it features two kinds of baths: an authentic dry sauna that melts away tension and a steam sauna rich in moisture. After cooling down in the cold plunge bath, head to the lush terrace lined with Adirondack chairs. A blissful open-air rest unique to Karuizawa awaits, surrounded by the breath of the trees and the murmur of the river.

The bath is filled generously with premium natural hot spring water from Oku-Kusatsu Onsen Kakurenoyu, a renowned spring in Kita-Karuizawa. This sodium bicarbonate and sulfate spring is known for its meltingly soft feel on the skin. As you sink in up to your shoulders, a gentle warmth spreads to every corner of your body, and accumulated fatigue seems to melt away. Enjoy a blissful bath time that lets you experience the blessings of this famous spring with your whole body while feeling Karuizawa's crisp air.

An authentic dry sauna where you can spend time surrounded by the scent of wood and a calm atmosphere. In a space wrapped in silence, you can step away from the hustle and bustle of everyday life and simply let the sweat flow in peace. Guests can enjoy a high-quality sauna experience filled with deep immersion and gentle tranquility, as if all five senses were being sharpened.

A steam sauna where soft vapor fills the room and gently envelops the entire body like cotton. Unlike the dry sauna, it is not hard to breathe, and the moisture-rich heat slowly penetrates deep into the skin. With every breath, a pleasant warmth spreads, and the stiff mind and body are gradually released. In this moisture-rich space that promotes beautiful skin, you can enjoy a dreamy level of relaxation.

A refreshing cold plunge bath where the clear waters of Karuizawa sharply cool down a body warmed to the limit in the sauna. After coating your whole body in a pleasant chill, head to the lush open-air rest terrace. Sit back in an Adirondack chair and let the cool highland breeze brush your cheeks, while the breath of the trees and the distant murmur of the river gently stimulate your senses. A blissful cooldown awaits, one that blends completely with Karuizawa's natural surroundings.
