Koguriyama Mountain Lodge

I love Onsen and have stayed at many Accommodations across the whole country, including luxury Ryokan, but Koguriyama Sanso stands out for its deeply satisfying meals, the best Onsen where you can always soak in peace and relaxation, the wonderful view from the window, and the quiet, luxurious time surrounded by nature—along with the hostess’s bright and welcoming personality. It is a memorable place I want to visit again even if it’s far away. Whether you’re traveling solo, with family, or in a group, I highly recommend this Accommodation for warmly welcoming everyone.

We stayed here as a base for a ski trip to Naeba, Suhara, and Kagura. Since we chose an expressway discount plan with a lift-ticket set for touring multiple resorts, we didn’t worry about the distance to the nearest interchange. We narrowed down options across several areas and booked based on this priority: a high-quality Onsen available anytime > location (quiet and tucked away) > price. The Onsen is pleasantly lukewarm with soft water quality—I’ve lost count of how many times I soaked. It feels like being wrapped in a futon, and it’s so relaxing that once I soaked absentmindedly without even turning on the bath lights before evening… and before I knew it, it was midnight. Unlike circulated baths that make you sweat heavily in 5–10 minutes, this one is different: no matter how many times I bathed, my skin never felt dry. On the guestroom floor there is a microwave, vending machines for soft drinks, alcohol, and snacks, plus a jug of local spring water. It seemed like soft water and tasted great—I refilled it many times. I’ll stop here—if I praise it too much, I might not be able to get a Reservation next season. Thank you for a wonderful trip.
