From 2005 to 2013 among 7 districts with different vulnerability to disaster, we conducted a questionnaire survey concerning how people maintain their traditional wooden houses and compared the result with the disaster measures of the areas. Following results are obtained. 1) In all surveyed districts, seismic retrofitting had rarely been taken by the residents because of economic pressures and property inheritance issues. 2) There are familiar carpenters or trends among 7 districts, but only a few houses are maintained at fixed intervals. It is important to appropriate maintenance in order to preserve houses from earthquakes.
