Fujitsu launches made-in-Japan next-generation CPU FUJITSU-MONAKA

Kawasaki, Japan, September 14, 2026

Fujitsu Limited today announced that it will begin global sales of its next-generation CPU, FUJITSU-MONAKA [1], designed and developed in Japan, starting November 2026. This will include sales of the processor as a standalone product to cloud and data center operators and server vendors. Additionally, the company will launch the made-in-Japan Fujitsu MONAKA Server equipped with the FUJITSU-MONAKA CPU, offering high reliability and power efficiency as a sovereign AI infrastructure. Fujitsu MONAKA Server will be made broadly available from November 2026 to data center operators, enterprises, and the academic and HPC sectors in Japan and Europe, as well as to the defense sector, contributing to national security.

In recent years, the expansion of generative AI has led to a shortage of computing resources and a rapid increase in power demand, posing new management and societal challenges. This has heightened the importance of low-power-consumption CPUs that can deliver higher processing performance with limited power. Simultaneously, there is a growing need for on-premises AI infrastructure that allows companies to manage and operate confidential information securely in-house, requiring AI infrastructure that can operate even in locations without specialized infrastructure like water cooling. Furthermore, with increasing geopolitical risks, interest in platforms that ensure supply chain reliability and transparency is also growing.

Features of FUJITSU-MONAKA and Fujitsu MONAKA Server

• FUJITSU-MONAKA CPU: Achieving High Performance, High Power Efficiency, and High Security

  FUJITSU-MONAKA utilizes a 3D-stacked architecture with a state-of-the-art 2nm process for the core and a 5nm process for the cache and I/O sections. By combining optimal processes for each function, it enhances cost efficiency and achieves high power efficiency and performance through Fujitsu's unique ultra-low voltage operation technology. It delivers world-class computational performance and data supply capabilities with a maximum operating frequency of 3.8GHz and memory transfer speed of 8800MT/s. The CPU provides hardware acceleration for matrix operations, which are central to AI inference, using dedicated instructions. Combined with SVE2 vector operations and software optimization, it achieves twice the throughput for AI inference compared to other CPUs. This enables practical AI inference performance from the CPU alone, offering the flexibility to deploy at the necessary scale even in locations with power and cooling constraints.

• Fujitsu MONAKA Server: Enhancing Transparency through Domestic Manufacturing for Sustainable Sovereign AI Infrastructure

  The Fujitsu MONAKA Server is designed, developed and manufactured in Japan for sovereign applications. Manufacturing takes place at Fujitsu's Kasashima Plant. This ensures traceability by making the origin of components and manufacturing history visible and trackable, thereby strengthening supply chain transparency and reliability. Starting November 2026, Fujitsu will begin selling 2U (two CPUs) and 1U (one or two CPUs) rack-mount servers, ideal for AI agents and AI inference, in Japan and Europe.
