The purpose of this study is to analyze the relation between the life history contains building, rebuilding and extension of Minka as well as change of family members, and change or follow the names of rooms or houses. According to “Sekiguchi family diary”, the main building added a retirement and mud walled warehouse as time went by. The lifetime of each building was quite long. Reuse of old materials and houses was often. Building by new materials was done only when the head of family had wedding or inheritance. As for the names of rooms, a main room with ‘toko’ was called ‘okunoma’ consistently even through the rebuilding or inheritance. For the daily living room, the new name ‘chanoma’ was adopted instead of ‘hiroma’ by the chance of rebuilding in Meiji era.
