In this paper, the ultimate horizontal resistant force of Japanese wooden houses considering the stiffness of both floor and non-structural walls is discussed. The analytical model has the restoring force characteristic composed of the floor, bracing bearing walls and non-structural plaster board walls. The results may be summarized as follows : The increase of floor stiffness does not make the ultimate horizontal resistant force increased efficiently. The easy calculation method gives the lower limit of the ultimate horizontal resistant force.
