The Minamihara 3645 is a weekend residence completed by Yasui Hideo Atelier in 2008. It is located in Nagano, Japan and is entirely surrounded by nature blocking the annoying noise of Tokyo.
All rooms are united with the nature because the functional yard is attached to every part of the house.
When building it, it was taking into consideration the view of Mt. Yatsugatake and the nature of Karuizawa.





















True sanctuary isn’t merely found, but woven. Here, architecture doesn’t dominate nature; it breathes with it. The view of Yatsugatake isn’t just seen—it becomes part of the home’s soul, dissolving the boundary between shelter and wild.
Thank you for that beautiful reflection. You’ve perfectly captured the essence of Minamihara 3645. We designed the space to let Yatsugatake become an integral part of the home’s soul, ensuring the boundary between shelter and nature truly dissolves. I’m glad this vision resonates with you.
