This study evaluated seismic performance of Japanese traditional wooden structure with stage. The earthquake resistance capacity was estimated to protect the Japanese wooden structure from an earthquake disaster. In the previous study, Kiyomizu temple did not collapse for the assumed Hanaore earthquake wave. However, the Hanaore fault has a possibility to generate about twice as strong as the assumed earthquake wave Therefore, this study conducted the inelastic earthquake response analyses for stronger input waves to see the limit state of this structure. The results showed that this structure was vulnerable to twice as strong as the assumed wave due to falling of the main columns. Key Words: Hanaore earthquake wave, traditional wooden structure, earthquake response, negative stiffness
