The seismic design of conventional wooden houses is based on just a minimum quantity of bearing walls which can resist lateral force by earthquake. But by analyzing the research of damage in the 1995 Hyogo-ken Nanbu earthquake, it was shown that most wooden houses are destroyed mainly because of serious problems in strucural planning, especially the arrangement of bearing walls. This fact suggests there are a lot of conventional wooden houses which have serious problem like this in other regions. This paper addresses problems in structural planning by investigation for arrangement of bearing walls of conventional wooden houses which were dealt with in part1. It is shown that most of them have enough quantity of bearing walls and their arrangement is well planned for earthquakes only on the interior part of buildings ; they don't have enough bearing walls on the exterior part of buildings. These wooden houses don't have enough strength against lateral force and torsion. Though they have enough bearing walls, their arrangement is not optimal to resist lateral force and torsion as earthqukake resisting element because of too many openings on the exterior part of buildings.
