Digital Realty Pledges $10B Japan Data Center Expansion Over Next Decade, Taps Country as Top Asia Growth Market

U.S. data center operator Digital Realty Trust is planning a major expansion in Japan, committing an additional $10 billion over the next 10 years as it positions the country as its most important investment market in Asia.

Chief Executive Officer Andy Power said the company expects demand for computing capacity to remain strong, underpinning the decade-long spending plan. The investment is aimed at scaling up Digital Realty’s footprint in Japan to meet growing needs from customers seeking data storage, cloud connectivity, and high-powered processing.

The expansion would significantly reshape the firm’s presence in the country. Digital Realty is targeting a near fourfold increase in capacity in Japan, which already represents its largest base in Asia. The strategy reflects a broader industry push to add data center infrastructure in key markets as digital services, artificial intelligence workloads, and enterprise computing requirements expand.

Japan has become a focal point for global data center developers due to its large economy, deep base of corporate and technology customers, and the critical role that reliable, low-latency infrastructure plays in modern digital operations. For Digital Realty, concentrating investment in this market underscores its view that Japan will continue to be a long-term hub for regional and international data traffic.

Power’s comments also highlight the scale of capital required to build out data centers—projects that typically demand substantial upfront spending on land, construction, power delivery, cooling systems, and network connectivity. With a $10 billion commitment spread across a decade, Digital Realty is signaling both confidence in future demand and readiness to compete in an increasingly crowded field of operators and investors pursuing similar opportunities across Asia.

Digital Realty, headquartered in the United States, operates data centers globally and has been expanding in major metropolitan regions where demand for colocated infrastructure is rising. Japan, as the company’s biggest Asian foothold, is central to that growth trajectory. The planned buildout is expected to substantially increase the company’s ability to host customer equipment and provide the supporting infrastructure needed for high-availability digital services.

The move comes as data centers increasingly sit at the heart of economic and technological strategy, supporting everything from consumer applications to mission-critical business systems. By boosting its capacity in Japan, Digital Realty aims to capture a larger share of that rising demand—and to reinforce the country’s role as a leading destination for data center investment in the region.

Why it matters

A $10 billion investment by a major U.S. operator could accelerate Japan’s buildout of digital infrastructure, affecting cloud providers, enterprises, and network carriers that rely on local capacity. Nearly quadrupling capacity would intensify competition among data center operators and could influence where new digital services are deployed. Investors and customers will be watching how quickly the expansion materializes and whether power availability and other constraints shape the pace of growth.
