7. The Completion of the Uchisaiwaicho Daibiru Building

Our company had been operating a prefabricated seven-story, eight-level self-propelled parking garage attached to the Hibiya Daibiru Buildings, but it ceased operation on October 31, 1979 and was to be dismantled and removed. The company considered constructing an office building in order to use the property effectively due to its location in the heart of Tokyo, but because the property was small (631 m2), we developed a plan to build an office building on that property combined with an adjacent property.

In June 1979, we arrived at a deal with Kokusai Denshin Denwa Co., Ltd. (now KDDI Corporation) for constructing a jointly owned office building that combined our property with their adjacent property 297 m2 in size. A neighboring organization, Shineikai, also decided to participate in the project. On March 31, 1980, a construction project got underway on a site with a total area of 1,104 m2.

  • The Uchisaiwaicho Daibiru Building at the time of its completion

A committee called the Three-Party Joint Building Construction Preparation Committee (later renamed the Three-Party Joint Building Construction Committee once construction was fully underway) was established. Murano & Mori Architects was commissioned to design the building, and Kajima Corporation was commissioned for the construction by special order. The groundbreaking ceremony took place on May 11, 1981.

The Uchisaiwaicho Daibiru Building, completed on January 31, 1983, was the first joint project for our company. The underground part of the building used steel-frame reinforced concrete construction, while the aboveground portion used steel-frame construction. A special construction technique was used to fill the insides of the pillars with concrete to increase earthquake resistance. The building had nine aboveground floors, two underground floors, and one penthouse floor. Its exterior consisted of an aluminum panel curtain wall with natural silver tones and bright colors for an innovative look.

The Uchisaiwaicho Daibiru Building was a joint venture between our company and two others—Kokusai Denshin Denwa and Shineikai—that all had different types of businesses. Our ownership stake was 67.198%, Kokusai Denshin Denwa’s was 26.125%, and Shineikai’s was 6.677%. (We acquired KDDI’s stake on November 29, 2002.)

The building was impacted by the recession and struggled with an occupancy rate of 28% when it opened, but by June 1983, five months later, it was fully occupied due to hard work put into attracting tenants.
