Hotel Analysis
Based on 1 sites · 254 reviews
A 3-star traditional onsen ryokan in Karuizawa's mountains. Guests frequently highlight the free outdoor onsen and serene natural setting.
Reviews repeatedly praise the 'excellent outdoor onsen with perfect temperature.' Front desk staff friendliness and retro vibe are common mentions. Couples enjoyed the quiet forest surroundings and onsen relaxation. Breakfast is mildly flavored, with mixed opinions.
However, the mountain location requires checking bus times. Taxis are needed without a car, and there are few nearby amenities. The old building feels dated.
Ideal for couples or solo travelers seeking self-driving trips and nature relaxation.
