Fujitsu Builds Physical AI That Moves Between Data Centers Based on Power Grid Demand

Fujitsu announced on 24th December the development of Kozuchi Physical AI 1.0, a framework integrating physical and agentic AI. The technology combines NVIDIA's software stack with Fujitsu's own systems to automate confidential business workflows.

But the more significant announcement came the same day. The University of Tokyo and Fujitsu launched a trial starting in January 2026 to shift computational workloads between regional data centers based on real-time power grid conditions and renewable energy availability.

Data centers are consuming enormous amounts of electricity because of AI. Instead of locating them where infrastructure exists, the trial proposes moving computation to wherever power is available and cheapest. A workload running in Tokyo shifts to Osaka if renewable energy is abundant there. It shifts back when conditions change.

The technology uses container architecture and Oracle Alloy's sovereign cloud infrastructure. The trial runs through March 2026 with planned expansion to include multiple regions and additional verification through Japan's next-generation communication infrastructure called APN.
