NTT is Japan's largest telco and a major investor in sovereign AI computing infrastructure, building domestic capacity through NTT DATA and its cloud services while developing IOWN — a next-generation optical network that aims to dramatically cut data center power consumption. Its investment in Rapidus and domestic AI hardware reflects Japan's whole-of-industry approach to semiconductor and AI sovereignty. As a major end buyer of AI servers and data center infrastructure, NTT's procurement directly shapes demand for the entire upstream supply chain in Japan.
