Konica Minolta Relocates Headquarters Function Amid Redevelopment of Hamamatsucho Building
Konica Minolta Inc. has relocated its domestic operations from the Hamamatsucho Building (Shibaura 1-chome, Minato-ku, Tokyo) to Shiba Park Building A (Shibakoen 2-chome, Minato-ku) in response to the redevelopment of its former office site. Operations at the new location officially commenced on June 11, 2025. The relocation site, widely known by its nickname “Gunkan Building” (literally “battleship building”), is a large-scale office complex that will gradually house Konica Minolta and its group companies.
The former Hamamatsucho Building, originally constructed in 1984 as Toshiba’s headquarters, was a 40-story high-rise office tower with a gross floor area of approximately 49,190 tsubo (approx. 162,600 sq. ft.) and standard floor plates of about 761 tsubo (approx. 25,150 sq. ft.). The building is now part of “BLUE FRONT SHIBAURA,” a large-scale redevelopment project led by Nomura Real Estate Development Co.,Ltd.. It is being replaced by twin towers reaching approximately 230 meters in height. The South Tower was completed in 2025, while the North Tower is scheduled for completion in fiscal year 2030. The new office, Shiba Park Building A, was completed in 1982 and offers high accessibility, located just a 2–3 minute walk from Shibakoen Station (Toei Mita Line) and Daimon Station (Toei Asakusa and Oedo Lines). The building features 24 elevators and expansive floor plates exceeding 1,800 tsubo (approx. 59,500 sq. ft.), a likely factor in its selection as the new base.
In October 2021, during the COVID-19 pandemic, Konica Minolta announced its “Greater Tokyo Area Office Optimization” strategy, establishing a three-pronged structure: (1) JP Tower in Marunouchi (as headquarters and executive decision-making hub), (2) Hamamatsucho Building (business promotion and corporate functions), and (3) Tokyo Site Hachioji (including R&D in Hino). While the company still maintains multiple offices across Tokyo through its group companies, attention is turning to its next steps in office strategy.
