# Nikkei: NTT Data in final talks to build a 500 MW, $6.3B data center in Osaka for Anthropic

Nikkei reported on Oct 13, 2026, citing multiple sources, that NTT Data Group is in the final stages of talks to build a data center in Osaka for Anthropic. It would be Anthropic's first dedicated data center in Japan, with about 500 MW of power capacity, among the largest in the country. Construction could cost about 1 trillion yen ($6.3B), with a partial opening by 2028.

## Key facts
- Nikkei: NTT Data Group 'is in the final stages of talks to build a data center in western Japan for U.S. AI company Anthropic, multiple sources have told Nikkei'; the center 'would have one of the largest processing capacities in the country'
- Cost: could reach $6.3 billion (about 1 trillion yen) to construct; servers and GPUs would cost extra (W.Media, citing Nikkei)
- Capacity: up to 500 MW (Techmeme's summary of Nikkei; W.Media)
- Timeline: the companies aim to conclude talks by the end of NTT's fiscal 2026 (March 2027); partial operation by 2028
- Power: getting 500 MW from the grid is a challenge; on-site generation and fuel cells are being considered as a start (W.Media, citing Nikkei)
- Neither company has confirmed the talks (W.Media); Reuters carried the report as 'NTT Data in final talks to build Anthropic's first data centre in Japan, Nikkei reports'

## What happened

Nikkei's report (by Kosuke Shimizu, Katsuyuki Tanimoto and Shugo Tamura) says the deal is not signed yet. NTT Data would build and
operate the site in Osaka for Anthropic. The open part of the Nikkei article gives the $6.3B cost and the 2028 partial opening;
the 500 MW figure and the power plans come from Techmeme's summary and W.Media's account of the full article.

## Why it matters

It would be Anthropic's first dedicated capacity in Japan and one of its largest sites outside the United States, next to the
Norway (Volta/Bitdeer) contract and the Australian tender. For Japan, a single 500 MW AI site is close to one-seventh of the
country's installed data-center power (3.57 GW in 2026, per Mordor Intelligence as quoted by W.Media).
