NEW OPEN in Oshino Village, Yamanashi
A Private Mountain Retreat – Entire Cottage for Exclusive Use
Opening March 2026
Shiragane Sanso is a private, entire-rental cottage located in Oshino Village, Minamitsuru District, Yamanashi Prefecture.
Set slightly away from the main tourist areas, the property is situated in an exceptionally quiet location.
Surrounded by mountains, with very little traffic and almost no signs of daily life, it is a place where time seems to slow down.
While access by car is required due to its secluded setting,
this very remoteness is what allows guests to enjoy the true luxury of doing nothing at all.
A peaceful mountain hideaway—perfect for those seeking calm, privacy, and a deeper connection with nature.

Wake up to the sound of birds in the morning,
spend your afternoons relaxing in nature,
and enjoy quiet evenings beneath a sky filled with stars.
This retreat is especially well suited for those who love mountains and the natural world,
and for anyone wishing to step away from the noise and pace of city life.
Whether you’re staying with family or close friends,
or planning a workation or longer stay, the space is designed to let you slow down and settle in.
We aim to be a private, entire-rental retreat chosen by guests who feel the need to
“reset both mind and body in a truly quiet place.”
