This research aims to investigate the relationship between the earthquake diagnosis evaluation and the fundamental natural frequency based on the microtremor measurement. The unbalanced arrangement of the bearing wall reduces an earthquake-proof grade point for superstructure due to the effect of the eccentricity, even if the house was newly constructed after 1981 and the amount of bearing walls was enough against the Japanese Building Code. The earthquake diagnosis evaluated as a traditional wooden-framed house was applied to wooden houses older than 50 years, whose column size is smaller than 140 mm, so it is not adequate to treat as a traditional wooden-framed structure. The earthquake-proof grade-point as a conventional wooden-framed structure is compared with that as a traditional wooden-framed structure. The micro-tremor measurements are also employed to investigate the fundamental natural frequency of the house. Then it can be found that the superstructure grade-point increases with natural frequency of the wooden house, based on the micro-tremor measurement.
