Hot spring for beautiful skin that flows directly from the source
Hoshino Onsen is a natural hot spring found back in 1915 that flows directly from the source. The soft, thick water is said to wash away any impurities on the body, and a thin layer of salt will retain on the body as you leave the tub, keeping your skin moisturized. Since it removes and moisturizes, it is known as the hot spring of beauty.
Hoshino Onsen Tombo-no-yu
The baths provide a serene setting to enjoy Karuizawa's changing seasons—cherry blossoms, fall foliage, and snowy vistas—accompanied by refreshing mountain air. Outdoor baths feature rocks for a natural ambiance, while indoor baths boast cedar accents and wide windows with scenic views.
Meditation Bath
Exclusive to guests staying at HOSHINOYA Karuizawa, the Meditation Bath is a public hot spring facility with a space of both light and no light. The transition from light to dark blocks stimuli from the outside world, where one's senses are sharpened and can enter relaxation through meditation.
The Spa in the Restful Forest
Karuizawa National Wild Bird Sanctuary Forest at the foot of Mt. Asama has abundant nature, refreshing water and crisp air. You can enjoy the hot spring that gushes out and the food that is full of flavor, and your mind and body will get better as you stay as you live.
