Japan is moving the most precious piece of the AI era puzzle—compute—onto its own soil. Nippon Telegraph and Telephone Corporation (NTT) plans to build the company's first dedicated data center in Japan for the American AI firm Anthropic. This is not only another expansion of Anthropic's infrastructure footprint in Asia, but also reveals Japan's strategic calculation to keep a tight grip on domestic compute in the age of artificial intelligence.
The two sides will cooperate on AI computing infrastructure. The new data center is expected to deploy large-scale computing equipment dedicated to running and training advanced models, providing the foundation for the expansion of the Claude family's business in Japan and the Asia-Pacific region. In recent years, demand for generative AI has kept climbing, the compute needed to train and run large models has grown rapidly, and AI companies have been pouring money into building new facilities. As a major rival of OpenAI, Anthropic is also accelerating the densification of its global infrastructure network.
For NTT, this partnership can both expand its own data center business and help it claim a more prominent position in the AI infrastructure market. The Japanese government has in recent years been encouraging domestic companies to increase investment in AI and semiconductors, aiming to reduce dependence on critical digital infrastructure overseas while drawing more computing resources of international tech companies to be located in Japan.
The deeper motive is written in the words data sovereignty. As AI applications spread, more and more countries are beginning to value the security of computing resources and the ability to deploy locally—for customers such as finance, healthcare, manufacturing, and government agencies, running AI services within their own borders is becoming increasingly important. As a result, Microsoft, Google, Amazon, and Anthropic are all lining up to advance regional data center plans. Anthropic's business has surged with the backing of giants such as Amazon and Google, and Claude has become one of the world's major generative AI platforms. This placement of dedicated facilities in Japan through NTT is seen as a key step in strengthening its competitiveness in Asia.
Industry observers judge that as model sizes continue to balloon, data center construction itself will become one of the main battlegrounds of global tech competition. Japan's introduction of Anthropic's dedicated facilities not only enlarges the country's domestic AI compute pool, but may also spur the entire supply chain of servers, network equipment, electricity, and semiconductors. When a data center built for Claude is powered on on Japanese soil, the line of compute sovereignty gets traced once more, ever more clearly.
