The dynamic characteristics of traditional timber houses existing in Tochigi-prefecture are investigated from the microtremor measurements. The main results are as follows; The natural frequencies of traditional timber houses distribute from 2.5 to 5.0 Hz, and these values are approximately equal to those of contemporary timber houses, construction stage of which is frame work with bracing members. The damping constants of traditional timber houses distribute from 2.6 to 9.2 %, and these values are larger than those of contemporary timber houses by about 20 %. The damping constant is in inverse proportion to the natural frequency in case of traditional timber houses. It becomes clear that the number of wall and the weight of house are main factors to determine the dynamic characteristics of traditional and contemporary timber houses.
