Saito Shoten was established in 1889 as a lumber dealer in this area. The building is a modern Japanese-style building with the atmosphere of an independent house in the suburbs, and is well known as a landmark integrated with the nearby Shimura Isarizuka. The building was newly constructed in 1933 in conjunction with the expansion of Nakasendo (now National Route 17). It is designated as a tangible cultural property of the ward.
