Official Hotel of "Karuizawa Toy Kingdom," with dedicated rooms for babies.

Because we had such a wonderful stay last year with my preschool-aged child, this year the three of us—including my husband—stayed again. On the first day, we played at Toy Kingdom nearby. We entered at 1:00 PM, and the park closed at 5:00 PM that day, so it felt like there wasn’t enough time to do everything. There were athletic activities, rides, and events as well, and we had a very fulfilling time. As for the dinner buffet, there were plenty of kid-friendly options again, so we were very satisfied! The roast beef, seasonal pasta (soy milk lemon), and Basque cheesecake were especially delicious. My child was thrilled to find sushi, hamburg steak, and straight-cut fries and ate until completely full. We were also surprised to see watermelon even though it was October—my child went back for seconds. The milk was tasty too; they drank a lot of it. During other times, we enjoyed the mystery-solving activity included in our plan as well as fireworks. Even inside the hotel we didn’t have enough time—we kept having strategy meetings like “What should we do next?” With one night including two meals for three people plus fireworks and Toy Kingdom tickets included in the plan, JPY 37,000 is an incredible value. At other hotels we often end up with nothing to do after check-in and spend time feeling bored, but here you can truly have a packed and enjoyable stay. Also, in August I booked through another site but had to cancel on the day due to my child not feeling well. When I called the hotel that morning, the front desk staff handled it very kindly. Thank you again for your help then. We will definitely stay again next year!
