NTT DATA Group has announced the development of the Tokyo TKY12 Data Center, a massive new campus in the Inzai-Shirai area of Chiba Prefecture. The project, spearheaded by NTT Global Data Center (GDC), aims to meet the skyrocketing demand from global hyperscalers and domestic enterprises.
Situated in one of Japan’s premier digital infrastructure hubs, the TKY12 project will feature a staggering total IT capacity of approximately 200MW. The campus will consist of six high-density buildings designed to support the next generation of AI and cloud computing workloads. This development follows the nearby Tokyo TKY11 facility, a 50MW site scheduled to go live in April 2027.
Strategic Location and Resilience The site in Shiroi City was selected for its geographic stability—sitting roughly 20 meters above sea level with a low risk of natural disasters. Its proximity to major transit points makes it a logistical gem, located just 60 minutes from Tokyo Station and 20 minutes from Narita Airport.
A Sustainable Future In line with the "NTT DATA NET-ZERO Vision 2040," the TKY12 campus is being engineered for sustainability. The company aims to achieve net-zero emissions for its data center operations by 2030. By utilizing highly efficient power and cooling systems, NTT DATA intends to balance high-performance computing with environmental responsibility.
Community-First Development Beyond technical specs, NTT DATA emphasized a "hand-in-hand" approach with the local community. The project is being developed in close collaboration with Shiroi City officials to ensure the campus contributes to a sustainable local economy.
Services for the first phase of the TKY12 campus are projected to begin in 2030.
