About us

A littel bit about us...


Asama Kogen Hotel opened in 2014. We are Yukiko and Kohei, the owners, and we both live and love this area. It is our love of this region that inspired us to open this hotel, to share this beauty with you.


It has been a wonderful challenge for us, pursuing our dream of opening this place of beauty. It is our desire to offer you all this area has to offer; beautiful nature, trees, stars, and delicious local foods and produce.


Our project is not yet complete, and we are making improvements everyday. This year we painted the roof, we held several music concerts at our restaurant, we opened one private cottage for guests, as well as many other inspiring projects. We hope that this will be a place you decide to visit again and again, realising something new each time you come. We are growing quickly, and it is an exciting time for us here!
