NTT Data in final talks to build Anthropic's first data centre in Japan, Nikkei reports

Business Recorder, citing the Nikkei business daily, reported on Tuesday that NTT Data Group, a unit of telecoms firm NTT, has reached the closing phase of negotiations to construct a data centre in Osaka for Anthropic, a US AI company. The Nikkei drew on information from several people familiar with the matter. NTT declined to comment, and the wider NTT Group could not be reached right away.

The facility would be the first dedicated site in Japan for Anthropic and could carry construction costs of up to 1 trillion yen, or $6.3 billion. Its power intake capacity would reach as much as 500 megawatts, with partial operations potentially beginning as early as 2028. Both sides are reportedly aiming to sign an agreement before fiscal 2026 ends on March 31.
