The national research project to investigate proper structural design method for CLT (Cross Laminated Timber) buildings has been advanced by the subsidy of the Ministry of Land, Infrastructure, Transport and Tourism of Japan since 2011. This paper provides the outline of shake table tests executed as a part of the project in February 2015. Two specimens, one (Specimen A) is five story and another (Specimen B) is three story, were tested. As the result, for both specimens damage was rather slight by the strong input wave according to the Building Standard Law of Japan. Finally, Specimen A survived three dimensional input wave of 100% of JMA Kobe (strong ground motion recorded during Kobe Earthquake in 1995), and Specimen B survived 140% of JMA Kobe.
