Numerous Buddhist buildings have unevenly distributed walls and heavy roof, it is easy to fall-down during earthquake. This research conducted experiments to clear vibration characteristics of an existence temple. 1) The natural frequency are f_<1NS>=2.0Hz and f_<1EW>=2.4 Hz, respectively. 2) Twist pitch frequency is f_<1T>=2.6Hz and it has a possibility that mutual vibration will take place with f_<1NS>. 3) In response to the influence of the roofed passage located at the east side of the building, the amplitude of the south-east corner is controlled. However, f_<1T> of twist is closely f_<1NS>, because it has danger when earthquake of large ground-motion. 4) As compared with woody residence, wall rate is very little, and weight of the roof is 4 times per unit area. For earthquake improvement, south-east corner of the building needs to be reinforced.
