Come and stay at Karuizawa’s comfortable & friendly Japanese inn

Ikoisanso is a small inn with a history in Karuizawa dating back six decades. The laid-back atmosphere created by its woodland surroundings is welcoming and nostalgic. Just a ten-minute walk from Naka-Karuizawa Station, it is situated at the epicenter of one of most beautiful resort areas of Japan.

In addition to a series of structural and amenity renewals in 2016, we added glamping and BBQ facilities for you to enjoy from springtime to fall. Our staff will propose the best way to enjoy Karuizawa according to your style and preferences. We’re confident you’ll love your stay with us, and always come back to Ikoisanso.

We look forward to welcoming you with open arms, fully devoted to making your stay unforgettable.
