TOKYO, Nov 7, 2025 - (JCN Newswire) - TANAKA PRECIOUS METAL GROUP Co., Ltd. (Head office: Chuo-ku, Tokyo; Group CEO: Koichiro Tanaka) announces that its new head office, the TANAKA Building, constructed in Nihonbashi Kayabacho, Chuo-ku, and to which the head office functions were relocated on April 1, 2024, has been chosen as a winner of the GOOD DESIGN AWARD 2025, which is organized by the Japan Institute of Design Promotion (JDP).
The Vision Behind the New Head Office, TANAKA Building
The founding location, Kitajima-cho, Nihonbashi-ku, Tokyo (now Nihonbashi Kayabacho, Chuo-ku), served as the head office of TANAKA from 1885 to 2006, when the head office functions were moved to Marunouchi. In April 2024, as a leading company in the precious metals industry, driving the forefront of the times while upholding its founding philosophy and aiming for further development, TANAKA relocated its head office functions back to its birthplace, Kayabacho—a district undergoing remarkable evolution through the redevelopment of the surrounding area and the creation of new hubs for intergenerational exchange.
The new head office was designed under the concept “Connecting with people, the city, and the future.” It embodies the vision of a place that brings together diverse people and values to create the future. The exterior adopts a calm color scheme, and limited space is effectively utilized by incorporating greenery to provide a feeling of nature, aiming for harmony with the tranquil, historically cultivated streetscape of Kayabacho.
Inside the building, a central staircase in the atrium promotes open and liberating communication and encourages barrier-free interaction among employees. Furthermore, to support Activity Based Working (ABW)—a work style that allows employees to flexibly choose where and when they work according to their tasks and circumstances—the office layout incorporates diverse spaces such as free-address seating, web-compatible booth seats suitable for individual work, and meeting spaces that can flexibly accommodate different group sizes.
The building’s overall design has been recognized for reducing energy consumption by 51% compared to conventional buildings, achieved through lowering environmental load during construction, adopting high-efficiency equipment, and actively utilizing natural energy. It meets the standards for ZEB (Zero Energy Building) Ready.
Evaluation Comment from the GOOD DESIGN AWARD Judges:
The new head office, which has returned to its founding site, embodies in its architecture the clear theme of connecting the “city,” “people,” and the “future.” On the first floor, there is a hall and a display of a mikoshi (portable shrine) used in local festivals, expanding opportunities for interaction with the local community. The large atrium, Crucible Space, which runs through the center of the office, serves as a symbolic area that brings in light and wind while encouraging encounters and collaboration among people. Equipped with systems for seismic isolation and environmental consideration, this architecture embodies the image of a company that builds on its history and continues into the next generation.
