Abstract
The Draft Bills of Tokyo City Building Ordinance, planned by Dr. Yorinaka Tsumaki since 1889, were repealed, but they played an important role in the history of building law. The structural regulations in them have characteristics as follows: 1) For the first time, Dr. Tsumaki introduced the regulations about iron frames, the earthquake-proof regulations on a building built of brick and stone into these draft bills. 2) These draft bills were referred to a large number of foreign building code. These draft bills didn't imitate all of them, but these draft bills also had their own originality. 3) These draft bills were partially referred to the next Draft Bills of Tokyo City Building Ordinance planned by members of A. I. J. . But the questions how they were selected, remain.
