Abstract
Building-Standard-Law has lower-limits and inspection-system. We tried to clarify that there are prefectures whose ratio of inspection of buildings called“Building-Standard-Law order No.2”are over 90%, second, to clarify that the current way of calculating the percentage is not useful, third, to clarify that there are many prefectures where calculating is not useful. As the result, we found there are actually only two prefectures where the rates of inspections are above 90%, we found that the current way of calculating the percentage is not useful, we found that it is more practical and effective to talk with each building owners.
