What's on the table
The project's construction cost is projected to top out at up to $6.3 billion. Partial operations are targeted for 2028. Anthropic would be the anchor customer for this site. It would mark the company's first dedicated data center in Japan, giving it local infrastructure in one of Asia's largest economies.Why Japan, and why now
Japan is facing challenges in keeping pace with surging demand for generative AI. Demand for computing power is climbing faster than the infrastructure built to serve it.NTT's Kansai buildout is already underway
In April 2026, the company opened the Kyohanna OSK11 data center in the Kansai area, which it bills as AI-ready. OSK11 has a capacity of 30 MW. NTT is also deploying what it calls the AI-Optimized Wide-area Network, or AIOWN, to support low-latency AI workloads.Key signals to watch
Key signals to watch include a formal announcement confirming the agreement, any update on the facility's final capacity, and whether NTT stays on track for its 2028 partial launch. Progress toward the 1 GW target by fiscal year 2033 will also show whether Japan can close its AI computing gap.#Japan#NTT#DataCenter#AI
