This paper presents the results of lateral shear performances and hysteresis characteristics of the mud walls that have been made by three plasterers in Kyoto. The specifications of the mud walls and the mixing preparation of materials are different in those ones, but the material of mud before mixing is the same. In the results of the test, envelope curves were almost the same until maximum strength. The coefficient of the effective wall length is about 1.8. In this tests, strength of the wall was reduced after tearing of mud wall.
