An open-air hot spring bath with free-flowing natural spring water. A highland resort at an elevation of 1,130 meters.

To all the staff at Karuizawa Club Hotel 1130, thank you as always for your kind support. My family has stayed here many times over the past few years, and this time we were finally able to make a Reservation for the Premium Family Suite Room we had long hoped for, so we stayed yesterday. As its name suggests, it was the highest-grade Room among the many Rooms at Karuizawa Hotel 1130. There was an open-air jacuzzi bath on the balcony, and two indoor baths inside as well. There were also two restrooms, and four separate rooms in total—one of them a bedroom with a skylight that lets you gaze up at the sky. Because every space was so luxurious, my whole family was thrilled the moment we stepped into each room. We had reserved Japanese kaiseki at Yamaboshi well in advance, but it was changed to a buffet Plan. Just like in Hewitt Resort’s TV commercial, the buffet venue was beautiful and the selection was extensive. From the live kitchen at dinner to freshly made rice balls at breakfast, everything exceeded our expectations. The staff were all courteous and kind, which helped us greatly. We also visited the open-air bath at Onioshi Onsen; it had been renovated and made it easier to access directly from the indoor bath area. We will be staying one more night later this month as well, and we are looking forward to enjoying the same Premium Family Suite Room again. Each time we stay, this wonderful Hotel continues to evolve even further—and it has become our family’s favorite. I hope other guests can experience that same sense of excitement too. To everyone on staff at Hotel Karuizawa 1130, thank you very much as always.
