A temple is considered to be difficult to resistant large earthquakes because of its poor resistant wall and heavy roof. In order to estimate the dynamic characteristics of four temples standing at Shizuoka prefecture, we carried out microtremor measurements. The main results obtained from microtremor measurement of four temples are as follows. Natural frequencies distribute from 2 to 3 Hz and those of EW direction are larger than those of NS direction with about 3 %. Damping constants distribute from 2 to 5 % and are in proportion to the weight of temples. Swaying and rocking ratios to the absolute displacements at ceiling height level are less than 10 % and less than 5 %, respectively. Torsional angle between first and second floor has a tendency of inverse proportion to the length of first floor plane of temple.
