Nakadanaso - Karuizawa 4-Star Accommodation

Reviews frequently praise the unique apple-filled onsen bath. The open-air bath is clean and warming, with delicious local cuisine using regional ingredients. Staff's attentive service and the warm ryokan vibe are often mentioned.

However, it's hard to access without a car, and the onsen requires climbing about 50 steps. The old building has shared bathrooms, feels cold, and has poor soundproofing with noise from neighboring rooms. Those with knee issues or using wheelchairs may find it inconvenient.

Couples and solo travelers often say it's great for a peaceful summer retreat.
