In this study, the authors have investigated the vibration characteristics of the Kawagoe kura-zukuri buildings that are traditional wooden building with heavy mud wall. It is necessary to estimate an earthquake resistant capacity of the Kawagoe kura-zukuri building. Then, in order to observe vibration characteristics which are natural frequency, natural period, natural vibration mode and damping factor, the microtremor measurements were carried out with twenty-two servo acceleration sensors for five Kawagoe kura-zukuri buildings. Three sets of microtremor measurements were carried out for a duration of two minutes. The followings were confirmed; (1) The first natural periods of the Kawagoe kura-zukuri buildings were between 0.17 and 0.47 second. (2) The first damping factors of the Kawagoe kura-zukuri buildings were between 2.31 and 4.95 %.
