Industry Background

• Data centers have evolved from mere storage facilities to critical modern digital infrastructure. Widespread adoption of cloud services, IoT, and the rapid growth of generative AI have driven exponential increases in data processing volumes, making data centers a key high-growth industry theme.
• The rise of high-performance AI servers has shifted industry focus from simple capacity expansion to qualitative requirements: stable power supply, advanced cooling technology, and strategic location. These factors are not easily substituted, creating a structural advantage for firms that have made early cumulative upfront investments.
• Domestic Japanese generative AI initiatives, such as the joint ecosystem development agreement between NICT, Preferred Networks, and Sakura Internet, are expected to further boost domestic data center demand, increasing the sector's importance going forward.
