The Ise and Owase towns in Mie prefecture, which will be the most heavily damaged area in the next Tonankai earthquake, are selected to consider how to reduce the seismic damage of traditional wooded houses in the rural area facing the problem of depopulation and aging. A questionnaire survey for local residents and evaluation of seismic capacity and durability for existing houses are performed. As a result, the following conclusions are obtained. 1) Seismic retrofit can be carried out when existing houses are extended according to the lifestyle modification. 2) Structural design for extension or seismic retrofit should be carried out appropriately so as not to increase eccentricity or decrease deformation performance. 3) Regular maintenance once every ten years are also effective to reduce damage.
