NTT DATA Keihanna OSK11 Data Center - 30MW AI-Ready Facility
Status: Operational / Live | Location: Soraku-district, Kyoto
Project Overview
The NTT DATA Keihanna OSK11 Data Center, officially launched on April 9, 2026, represents a pivotal expansion of Japan’s digital infrastructure within the Kansai region. Strategically positioned in the "Keihanna Science City" (Kyoto-Osaka-Nara border), this facility is designed to meet the explosive demand for Artificial Intelligence (AI) and high-performance computing (HPC) workloads. As NTT DATA’s 14th data center in Japan, OSK11 serves as a critical alternative and complement to the saturated Tokyo market, providing much-needed geographic diversity and disaster recovery capabilities.The facility is built to "AI-Ready" standards, featuring high-density power configurations that can support the intense heat and energy requirements of the latest GPU clusters used in generative AI. By integrating advanced liquid cooling options alongside high-efficiency air cooling, the center ensures that hyperscalers and enterprise clients can scale their AI models without performance throttling.
