NTT in Talks to Build Anthropic's First Japan Data Center
NTT Data Group is in advanced negotiations to build Anthropic's first dedicated data center in Osaka, Japan. The planned site is in Osaka, and the price tag could reach up to $6.3 billion. If the deal closes, Osaka would host one of Japan's largest computing facilities, measured by processing capacity, built for a single AI developer. The project's construction cost is projected to top out at up to $6.3 billion. Partial operations are targeted for 2028. NTT is also deploying what it calls the AI-Optimized Wide-area Network (AIOWN) to support low-latency AI workloads. This project fits into NTT's broader plan to grow its domestic data center IT power capacity from approximately 300 MW to around 1 GW by fiscal year 2033, backed by an investment exceeding $9 billion. The Kyohanna OSK11 data center, which NTT opened in the Kansai area in April 2026, has a capacity of 30 MW. NTT is the leading colocation provider in Japan, and the Osaka project addresses the growing demand for generative AI in the region, which is outpacing available infrastructure.
