Abstract
The organization of the Postal Architecture changes its style from public to private since 1886 as the starting point of the ministry of Posts and Telecommunications. The Postal Architecture has also the history that they have designed post offices, training facility for employee, employee's accommodation, hospitals, etc., and supervised their construction projects for 140 years over. This Study makes clear why Postal architects' project management has been established as architect's leading organization in the former ministry of Posts and Telecommunications (1886-1949) in the Meiji, Taisho, and early Showa era by study of related research books and thesis.
