NTT Hibiya Tower, Tokyo, Japan
Within the Tokyo Cross Park masterplan, the NTT Hibiya Tower – a 230-metre tall and 361,000 m² tower – is one of Japan’s most advanced mixed-use developments. Purpose-built around IOWN, NTT’s light-based digital infrastructure, the building redefines what a headquarters can be, faster and radically more efficient. IOWN delivers up to 125× more data capacity, 200× lower latency, and 100× lower energy consumption than conventional networks, transforming the tower into a living platform for the future of urban life.
