日本万国博覧会会場設計プロセスと共同設計に関する研究

抄録

 This research clarified the following three points on the venue design process for EXPO’70 and five types of Tange’s collaborative design projects.

 1. The author ordered the design process of the symbol zone chronologically based on the minutes of official meetings and the construction process chart for EXPO’70.

 2. The author visualized the design process of the symbol zone based on the drawings and model photos of the venue plan for EXPO’70.

 3. The author classified the collaborative design projects in which Tange participated into five types, and considered the relationship between the design process for the symbol zone and these five types of projects. The author clarified the following three points about the collaborative design for EXPO’70:

 3-1. Tange and Uzo Nishiyama were both famous professor-architects, and it was very difficult to put together their different ideas.

 3-2. Tange managed the design office for main facilities of EXPO ‘70 as producer. Using his experiences at the laboratory, Tange encouraged the staff members to freely exchange their views.

 3-3. Tange and Taro Okamoto previously worked together for the design for the Tokyo Metropolitan Government Office in 1958. Okamoto’s elevated ideals to integrate art and architecture later realized in their proposal for the “Taiyo no tou (Tower of the Sun)” at the Omatsuri Hiroba (Festival Plaza) in 1970.
