What Travellers Say
Reviews Summary
Visitors consistently praise Karuizawa Onsen for its beautiful natural settings and the therapeutic quality of its waters, with many highlighting the serene outdoor baths. While generally positive, some note that the women's bathing areas can sometimes feel limited in the number of pools.
"I wasn’t sure if I wanted to stop by since my hotel had its own onsen, but I’m glad I did. The outdoor baths are lovely and I had a nice time in here. Plenty of space as well since Hoshinoya guests are given private access for an hour in the morning."

"A day-trip bathing facility located in Hoshino Onsen, a hot spring that has been around since the Taisho Era. When paying the admission fee at the reception, you can get a rental towel for an additional fee. The changing rooms have heated floors, and the small bathtubs for bathing babies are available for rent. The indoor baths are beautifully green and smooth to the touch. The outdoor bath is lukewarm and happens to be the best location to enjoy the fluttering snow at the same time. A recommended spot in Karuizawa in winter."

"Well worth the 1500Y for day-use onsen! The outdoor bath boasts a beautiful view of the autumn maple trees. There is an indoor bath as well complete with a view of the garden outside. We love the friendly service and delicious food in the cafe too. Best of all, there is a public bus service just outside the onsen."
