This is the oldest house known of its building date in Iya region and is a very significant one as it retains the appearance of mountain village house of that time. The main building of family house was once that of the village head of Imai community built in the 11th year of Genroku (1699), which was transferred here during Tenpo period 1830 - 1844. The house has the style of “Naka-Nema-Mimadori” and is regarded as rather large private house in this region. The roof of house was rethatched in 2007.
