Section 1. Expanding the Building Management Business

4. The Completion of the Yaesu Daibiru Building

Japan began to experience tremendous economic growth in the 1960s, and with that growth, the demand for office space continued to expand rapidly. New, enormous office buildings were constantly being built in Osaka and Tokyo, yet there was still demand for more office space.

In order to meet that strong demand, our company made plans for the construction of new buildings. On September 12, 1963, we acquired a property 1,949 m2 in size at 1-2 Kyobashi, Chuo-ku, Tokyo for 2.4 billion yen and a property 2,645 m2 in size at 5 Koji-machi, Chiyoda-ku, Tokyo for 320 million yen from O.S.K. Lines. The first plan was to develop the lot at 1-2 Kyobashi. Based on a memorandum of understanding signed between our company and O.S.K. Lines, O.S.K. Lines demolished the O.S.K. Lines Building on the site in October 1963. Our company established the Tokyo New Building Construction Committee and proceeded with the plan in cooperation with Murano & Mori Architects, who was commissioned to design and supervise the project. In November of that year, we submitted an application for a construction permit to the Tokyo Metropolitan Government, and the following year, on March 23, 1964, the building was approved with the condition that construction begin within one year. The reason for the hurry is that the Building Standards Act had been revised on July 16, 1963, and the changes were going to take effect on April 1, 1964. This would allow the building to be exempted from district-based floor-area regulations and allow us to build an office building with nine aboveground floors and five underground floors as planned.

On December 17, 1964, a contract was signed with Kajima Corporation for construction of the new building by special order, and construction got underway on December 28. The building was completed on August 25, 1967, two years and eight months after the start of construction.

The new building, named the Yaesu Daibiru Building, used earthquake-resistant and fire-resistant steel-frame reinforced concrete construction. It had nine aboveground floors, five underground floors, an eave height of 31 m, a penthouse height of 43 m, and a foundation base depth of −21.68 m. The total floor area of 26,723 m2 was extremely large in comparison to the site area, because the basement had been excavated to the fifth floor in anticipation of the impending floor-area regulations in order to maximize the use of the site.

The exterior was clad in heat-treated black granite (Canadian black) with a rough surface finish from the first floor to the rooftop, giving the entire building an elegant look with a stately grayish brown color.

The internal structure was distinctive for having a direct underground corridor connecting it to the Yaesu underground shopping mall, thanks to an agreement with the Yaesu parking garage, which boosted its convenience. There was also a tree garden installed on the roof. The Yaesu Daibiru Building was a winner of a 10th BCS Prize award in October 1969.

The building opened on September 19, 1967, but due to a recession that took place at that time, the rental situation was quite challenging, and we had to wait until around 1969 for the building to reach nearly full occupancy.
