Digital Realty Trust has sharpened its Japan strategy with the Osaka 10 data center, a newly built, AI-ready facility aimed at hyperscale cloud, content and enterprise customers in the Kansai region. The colocation site, developed together with local partner Mitsubishi Corporation, adds much-needed high-density capacity for customers that want to deploy GPU clusters and latency-sensitive workloads closer to western Japan’s industrial and population centers. According to the company, Osaka 10 forms part of its broader Digital Osaka campus, which has been expanding in stages as demand for cloud services and data residency requirements grow across the country.

What Osaka 10 delivers for cloud and AI customers

Osaka 10 is located in the Kansai region, which includes Osaka, Kyoto and Kobe, positioning the facility close to a large base of manufacturing, financial and digital-economy customers that require low-latency connectivity. Digital Realty presents Osaka 10 as an integral building block of the multi-facility Digital Osaka campus, which is designed to offer scalable capacity from individual racks up to multi-megawatt deployments for hyperscale tenants. The company highlights that the campus is engineered with redundant power and cooling architectures as well as robust physical security, reflecting the operational standards expected by global cloud and platform providers. These characteristics are in line with Digital Realty’s global PlatformDIGITAL design approach for its larger campuses, which aims to give customers consistent infrastructure and operating processes across markets. Digital Realty’s Osaka campus overview describes the site as part of a growing regional hub for cloud and digital services.

While detailed public specifications for Osaka 10 are limited, Digital Realty’s disclosures around the broader campus emphasize support for high power densities, which is increasingly important for AI training and inference clusters built on modern GPUs and specialized accelerators. Customers are able to deploy cabinets and cages configured for higher-than-traditional rack power, backed by redundant uninterruptible power supplies and on-site generators sized for data center loads. Energy efficiency and sustainability are another focus area: the company notes that it is working to improve power usage effectiveness (PUE) across its Japanese portfolio and to source lower-carbon electricity where feasible, in line with its global science-based emissions reduction commitments. Independent market analysts expect Japanese AI and cloud workloads to drive continued demand for such high-density, energy-optimized infrastructure over the coming years as enterprises modernize their IT estates. Mitsubishi Corporation’s digital infrastructure business outlines the partners’ focus on scalable, energy-conscious data center developments in Japan.

Connectivity is a key differentiator for Osaka 10 within the Kansai region. The broader Osaka campus offers access to major domestic and international carriers, internet service providers and cloud on-ramps, giving customers multiple options for redundant network paths between Kansai, Tokyo and the rest of Asia-Pacific. This level of interconnection is crucial for use cases such as hybrid cloud architectures, edge caching for content providers and financial trading platforms that require predictable performance across regions. Digital Realty is also gradually rolling out its global interconnection and orchestration services across markets, enabling enterprises to create standardized network fabrics that connect their deployments in Osaka to other PlatformDIGITAL locations worldwide. Industry observers note that Osaka, alongside Tokyo, has become one of Japan’s primary landing points for new submarine cable routes, making carrier-dense data center campuses attractive locations for operators that need to interconnect with multiple subsea systems. A Reuters report on Digital Realty and Mitsubishi’s Japan expansion highlights growing investment in carrier-rich campuses serving Osaka and Tokyo.

Strategically, Osaka 10 underscores how important Japan has become in Digital Realty’s Asia-Pacific portfolio. The company has repeatedly said that it views Japan as a structurally growing market driven by cloud adoption, digital payments, e-commerce and initiatives to modernize legacy IT environments in both the private and public sectors. The expanded Osaka campus complements Digital Realty’s footprint in the Tokyo area, giving hyperscale and enterprise customers a dual-region option for resilience within the country’s borders, which can help address disaster recovery and data residency requirements. Longer term, data centers such as Osaka 10 are likely to benefit from AI-related demand, as Japanese corporations experiment with large language models, generative AI and high-performance computing workloads that require both high-density racks and stable power. For Digital Realty, a real estate investment trust focused on data centers, keeping pace with this local demand is one way to support stable occupancy and rental income streams from its Asia-Pacific segment.

Within the broader company context, the Osaka 10 facility is one of several development projects that Digital Realty and Mitsubishi are advancing in Japan to meet both local and international customer requirements. Management has flagged Asia-Pacific as a growth engine alongside North America and Europe, and new capacity additions in markets like Osaka feed into the REIT’s long-term contracted revenue base. For investors, the progress of these campuses matters because large, carrier-dense facilities are often leased to creditworthy hyperscale platforms under multi-year agreements. Shares of Digital Realty Trust (ISIN US2538681030) trade on the New York Stock Exchange under the ticker DLR; the stock last closed at $146.32 on 06/13/2026, reflecting how public markets are watching the company’s ability to execute on its global development pipeline, including in Japan.
