Our Story
Inspired by the ancient name “Formosa,” meaning beautiful island, and the rolling hills that surround us, Mosahills embodies the harmony between untamed landscapes and thoughtful design.
Nestled in Nagano’s stunning alpine landscape, our chalets bring together the thrill of adventure, the comfort of thoughtful design, and the quiet beauty of Japan’s four seasons. Here, connection comes alive: to nature’s changing rhythms, to local culture and traditions, and to each other — away from everyday distractions.
In winter, discover world-famous powder snow right outside your door. When the mountains turn green, explore hidden trails, mountain streams, and timeless villages. At Mosahills, every stay is more than just a holiday — it’s a moment to pause, share, and create memories that last long after the seasons change.
