Karuizawa Club Hotel Karuizawa1130 / Hewitt Resort - Tsumagoi 4-Star Accommodation

Reviews across sites repeatedly highlight 'fun indoor pool and relaxing open-air baths.' Families enjoyed the pool slides and lazy river with kids, while couples appreciated the bath temperatures and views. Buffet meals get praise for variety and taste.

However, it's hard to access without a car, and pool use requires extra fees, noted as drawbacks in many reviews. Some mention musty smells or dated facilities in rooms. Best suited for family trips.
