The collaboration strengthens the infrastructure for deep learning models and generative AI solutions in a high-performance and sustainable environment.
Digital Realty, formerly InterXion, a leading global provider of data center, interconnection, and colocation solutions, announced that the Japanese artificial intelligence company Preferred Networks, Inc. (PFN) has selected its data centerA data center or data processing center (DPC) … NRT12 in Tokyo as the base for its advanced AI computing platform. This decision marks a significant step in the development of infrastructure specifically designed to meet the growing demands of AI in Japan and around the world.
A strategic alliance to drive AI innovation
Preferred Networks, recognized as one of the most valuable companies in Japan in the field of artificial intelligence and deep learning, develops advanced technological solutions ranging from generative AI models to specialized hardware such as supercomputers and processors. Its recently launched platform, the Preferred Computing Platform, is optimized for deep learning workloads and is powered by MN-Core™ processors designed to deliver high efficiency and performance in AI.
To meet the requirements of its platform, PFN needed robust, efficient, and scalable digital infrastructure—factors that they found in NRT12. This data center, operated by MC Digital Realty, a joint venture between Mitsubishi Corporation and Digital Realty, was designed to offer rack power capacity of up to 150 kilowatts (kW) and employs advanced liquid cooling technologies to manage the high thermal densities of AI processors.
Infrastructure ready for the AI of the future
NRT12 is part of PlatformDIGITAL®, Digital Realty’s global network of over 300 data centers distributed across 50 metropolitan areas and 25 countries. This network provides businesses, institutions, and governments with a connected and adaptable platform that fosters innovation, data sharing, and collaboration on a global scale.
According to Yusuke Doi, Vice President of Computing Infrastructure at PFN, “The demand for robust and efficient infrastructure is vital to meet the growing needs of AI. Conventional data centers cannot handle the thermal and power densities required by advanced AI chips. We are excited to leverage Digital Realty’s platform to support the growth of our business.”
For her part, Serene Nah, General Manager and Head of Asia-Pacific at Digital Realty, emphasized: “Japan is adopting AI at an accelerated pace, and the need for rapid and efficient service deployment is essential. We are delighted to provide PFN with advanced, AI-ready infrastructure that will enable them to deliver high-performance computing and energy efficiency to their clients.”
A step toward full operation in 2026
Preferred Networks has already begun implementing its AI computing environment at NRT12 and plans to commence large-scale operations in January 2026. This data center not only strengthens PFN’s ability to serve key sectors such as manufacturing, healthcare, and materials but also helps consolidate Japan’s leadership in the development of AI technologies.
Through this collaboration, Digital Realty and PFN set a standard for next-generation digital infrastructure, integrating sustainability, high performance, and scalability. The alliance underscores both companies’ commitment to digital transformation and advancing artificial intelligence in Japan and the global landscape.
