Abstract
The drafts of building ordinance for the City of Tokyo were drafted by Dr. Yorinaka Tsumaki in 1889, and said to have been pigeonholed. Recently Dr. Tsumaki's drafts and other rerated materiales were found in the libraly of the Architectural Institute of Japan. The purpose of this study is to make clear the process of discussion and the substance of these drafts in 1890s, and to place them on architectural legal history. The process of discussion for these drafts is divided into two periods. In this paper, I argue about the substance of drafts in the first term before "Chosakai-dai-ichijikai-ketsugi", and in the latter term.
