Tokyo Tatemono Opens Next-Generation Office “Ave.Takanawa” at Shinagawa Station’s Takanawa Exit

2026/03/03

The office building “Ave.Takanawa,” located a four-minute walk from Shinagawa Station’s Takanawa Exit, was completed on Jan. 30, 2026, and will open on March 2, 2026. Developed as a joint project by Tokyo Tatemono and Maekawa, the property was created through the redevelopment of the former “Avenue Takanawa Maekawa Building.” Outdoor balconies have been installed on every floor, with a shared lounge on the fifth floor and a rooftop terrace at the top level. The typical floor plate is approximately 280 tsubo (approx. 10,000 sq. ft.), and the exposed “skeleton” ceiling design (no finished ceiling) secures an approximately 3-meter ceiling height beneath the main beams.

The Shinagawa Station Takanawa Exit area is entering a major transformation phase. “TAKANAWA GATEWAY CITY,” led by JR East, held its town opening in March 2025, and KDDI has relocated its headquarters there. Toward the grand opening on March 28, 2026, headquarters functions of companies such as Maruha Nichiro and Kobe Steel are also expected to cluster in the area. The property is positioned as a rare, newly built office supply coming to market ahead of the large-scale redevelopment. On the first floor, THE CITY BAKERY and the event space “GLAID PARK Shinagawa” are scheduled to open. Floors 5 and 6 will be operated by an expert office provider within the Tokyo Tatemono Group, offering shared office services and related uses.

On the sustainability front, the building is scheduled to obtain the top BELS rating, ZEB Ready certification, and CASBEE Wellness Office S-rank certification.
