The purpose of this study is to identify the bending creep behaviour of sawn lumber beam of Japanese Cypress and the compressive creep behaviour of full-size masugumi, which is one of the most important components in old wooden Japanese buildings in terms of both structure and decoration. As the former, practical size sawing (120×240×6000mm) was applied, and bending creep test was carried out for 4 years. As a result, approximate formula for bending creep behaviour was obtained. According to this formula, total deflection after 100 years later is estimated to be about two and a half times as big as initial deflection. As the latter, by using full-size masugumi component, which was modeled on that in national treasure building "Toshodaiji Kondo", compressive creep test was carried out for 4 years. As a result, approximate formula for compressive creep behaviour was obtained. According to this formula, total compressive deformation after 100 years is estimated to be about five times as big as initial deformation.
