This building was built in 1911 as Karuizawa Post Office. Then it was used as Karuizawa Tourism Association from 1971. I don't know when, but the building was expanded.
It was relocated to Karuizawa Taliesin Park in 1996 and was restored to its original appearance.
The building was registered as a tangible cultural property in 2008.
