A quiet second home in the forest, living in harmony with nature

SANU 2nd Home is a “second home” where you can truly unwind and awaken your senses. Step back from the pace of city life, feel nature with all five senses, and live with your own hands in a place made for everyday living. Among the SANU 2nd Homes across Japan, Kita-Karuizawa 2nd is an ideal base for those who want to spend quiet time away from the urban bustle. Surrounded by greenery, you can lose yourself in thought or reading, or stay active with hikes on Mt. Ko-Asama and Mt. Asama-Kakushi. The white cabin is an eco-conscious retreat designed in harmony with the earth. Inspired by a beehive, it features a distinctive form and large windows that frame the surrounding landscape. The space comes alive through seasonal views reflected in those windows and wildflowers arranged in the dining room vase. In the morning, quietly grind coffee beans on the terrace as sunlight filters through the trees. In the afternoon, play a seasonal music playlist and let yourself sink into sound. In the evening, toast with natural wine while listening to insects sing. At night, add logs to the fire and drift into deep thought. How you spend your time is entirely up to you. Find what feels just right for you.

  • We stayed here for my partner’s birthday trip. Surrounded by nature in a quiet setting, we were able to step away from everyday life and spend a truly wonderful time. The room was very clean, and the Facility and amenities were well equipped, so we stayed comfortably without any inconvenience throughout our stay. The size was just right, and it felt like a very cozy space for two adults. The sauna is electric, so even someone like me who isn’t used to wood-fired saunas could enjoy it easily—and it still felt authentic, which was more than satisfying. Before our stay, they also shared helpful information such as the destination (Google Maps), what to bring, and recommended nearby places, which we really appreciated. Next time, we’d love to stay for multiple nights!
