Construction Begins on Landmark NTT Hibiya Tower in Tokyo

Construction officially began in December 2025 on the 230-m-tall, 361,000-m² NTT Hibiya Tower, which will serve as the new global headquarters for tech company NTT and “redefine the role of the corporate skyscraper through advanced digital infrastructure, sustainability and mixed-use urban design,” the Council on Vertical Urbanism reports. Developed by NTT Urban Development and Tokyo Electric Power Co., the building will deliver 150,000 m² of column-free office space that will “dynamically respond to users’ needs through biometric sensing, AI-drive environmental control and robotic configuration.” At its base, NTT Hibiya Tower will feature the three-story Cross Gate Atrium integrating retail, cultural and civic uses. Slated for completion in 2031, the tower is a central element of the 1.1 million-m² Tokyo Cross Park Vision masterplan that will transform 6.5 ha of central Tokyo into a mixed-use district anchored by four high rises, slated for full build-out in 2037.
