We report the results of static friction tests between column base and foundation stone of Japanese traditional timber buildings. Through the tests, we examined the effect of the shape of the column section, rotation angle of the column, the number of loading cycles on the variation of the static friction coefficient. The friction coefficient obtained from the test ranged from 0.7 to 0.9 in the first loading cycle. Up to 30% reduction was observed in the second loading cycle. In addition, we examined the friction coefficient between column base and concrete foundation, where the reduction in the second loading cycle was more significant.
