Site amplification factors were evaluated for strong-motion sites in Japan by using the spectral inversion technique. The seimic moment calculated from the source spectra, which were obtained through the analysis, agrees well with that of the CMT solution of the F-net, indicating the validity of the newly-introduced criteria to determine the reference site. Because the site amplification factors obtained in this study include the effects of later phases, they are suitable to be used for simulating strong ground motions by Kowada's method. Strong ground motions from the 1995 Hyogo-ken Nanbu, the 1968 Tokachi-oki and the 2003 Tokachi-oki eathquakes were simutated by the method to confirm the usefulness of the site amplification factors obtained in this study.
