Item 7. Establishment of the Toyota Technical Center

Engineering facilities during the founding period

At the Koromo Plant, completed in November 1938, the Engineering Department facilities were installed on the north side (near the current Office Building No. 2) of the Head Office building in Toyota City, while buildings such as the Design Office, Chemical Laboratory, and Vehicle Testing Office were lined up on the south side (Table 1-48). The combined total floor area of all engineering department facilities, including the Administration Office and the Aircraft Research Office, was 3,947 square meters. All of these facilities built during the founding period of the Koromo Plant were still being used after the war, except that the Aircraft Research Office was changed to a prototyping plant.

When development of the Crown began in 1952, Toyota Motor Co., Ltd. was producing the BX large truck, the SG small truck, the SF compact passenger car, and the BJ four-wheel drive car, and the company was expecting to increase the number of models as cars became more popular.1 Furthermore, Toyota had adopted a completed vehicle sales method beginning with the BX large truck developed in 1951 and was planning to internally design and manufacture the body for the RS Crown then under development, further increasing the number of vehicle development and design steps required. Thus, expansion of the engineering department became an urgent necessity.
