NTT in Advanced Talks to Build $6.3B Anthropic Data Center in Japan

NTT Data Group is in advanced negotiations to construct Anthropic’s first dedicated data center in Osaka, Japan. The proposed facility has a projected construction cost ceiling of up to $6.3 billion. Partial operations are targeted to begin in 2028, which would position the site as one of Japan's largest computing facilities built for a single AI developer. Anthropic would act as the anchor customer, securing local infrastructure in a market facing a severe generative AI computing gap. The project aligns with NTT's broader $9 billion initiative to expand its domestic data center capacity from roughly 300 MW to 1 GW by fiscal year 2033.
