## Summary

Fujitsu has announced the global launch of its FUJITSU-MONAKA CPU and the associated MONAKA Server, positioning them as critical infrastructure for sovereign AI. Starting in November 2026, the 2nm processor will be available to cloud operators and server vendors worldwide, while the fully Japanese-manufactured server will target data centers, enterprises, and defense sectors in Japan and Europe. The initiative addresses growing concerns over supply chain reliability, geopolitical risks, and the escalating power demands of generative AI.

The MONAKA CPU utilizes a 3D-stacked architecture combining 2nm core technology with 5nm cache and I/O sections, achieving a 3.8GHz clock speed and 8800MT/s memory transfer rates. By incorporating dedicated hardware acceleration for matrix operations and SVE2 vector instructions, Fujitsu claims the processor doubles AI inference throughput compared to competitors. This efficiency reportedly halves the number of servers and power consumption required for equivalent workloads, enabling practical on-premises AI inference even in locations lacking specialized cooling infrastructure.

The server lineup includes 1U and 2U rack-mount models equipped with CDI/CXL technology to mitigate memory constraints. Manufactured at Fujitsu’s Kasashima Plant, the systems emphasize supply chain transparency and support confidential computing via Arm CCA. Fujitsu plans to integrate these servers with its Kozuchi AI platform and Takane generative AI tools, creating a vertically integrated sovereign AI stack for financial, telecommunications, and manufacturing industries.

## Key points

- FUJITSU-MONAKA CPU uses 2nm process and 3D-stacked architecture to double AI inference throughput.
- MONAKA Server is manufactured in Japan to ensure supply chain transparency and national security compliance.
- Systems support confidential computing via Arm CCA and operate efficiently without specialized cooling infrastructure.

## Why it matters

This launch provides a secure, energy-efficient alternative to GPU-centric AI infrastructure, addressing critical supply chain vulnerabilities and power constraints. It enables organizations to deploy sovereign AI solutions that maintain data sovereignty and operational autonomy.
