Status: Under Construction | Location: Minato Ward, Tokyo, Japan (Adjacent to Tokyo Tower)
The NEXTDC TK1 Tokyo Data Centre signifies a strategic expansion into the highly competitive and technologically sophisticated Japanese market, which is a cornerstone of the Asia-Pacific digital economy. Located in the densely populated Minato Ward, adjacent to Tokyo Tower, the facility is being constructed as a 28 MW Tier IV-designed hub. This designation reflects a commitment to the highest levels of reliability, fault tolerance, and operational sustainability required by global hyperscalers, major enterprises, and defense organizations.
The timing of the project, with construction commencing in late 2025 and commissioning expected by 2027/2028, is directly aimed at capitalizing on Japan's surging adoption of Artificial Intelligence (AI) and advanced digital services. The facility's design is AI-ready, incorporating advanced cooling systems and explicit provisioning for Direct-to-Chip Liquid Cooling to manage the extreme thermal densities of modern GPU clusters. This capability ensures that TK1 can accommodate the next generation of high-performance, low-latency workloads.
Operating within the Greater Tokyo Area, the world's largest metropolitan economy, the facility benefits from exceptional Network Connectivity, offering seamless, low-latency access to major cloud platforms and financial trading systems. Its strategic urban location contrasts with typical massive greenfield campuses, prioritizing immediacy and low-latency for enterprise and edge compute needs, rather than sheer size.
NEXTDC's entry into Tokyo leverages the company's reputation for highly reliable, certified infrastructure. While the project size (28 MW) may seem modest compared to gigascale campuses, its premium Tier IV design in a core metropolitan area, coupled with its focus on high-density AI infrastructure, makes the TK1 Tokyo Data Centre a critical development. It reinforces Tokyo's position as a Tier-1 Global Data Centre Market defined by technological advancement, stability, and secure, high-quality digital real estate.
