Japan-based technology manufacturer Fujitsu has announced the commencement of sovereign AI server production at its Kasashima Plant, with manufacturing of initial units scheduled to begin in March 2026.

The servers are designed to support mission-critical operations for organisations operating under Japan's Economic Security Promotion Act, which requires designated essential infrastructure providers to maintain stringent data security, operational autonomy and full supply chain traceability. Fujitsu identified geopolitical shifts, rising cyber threats and evolving regulatory demands as the primary drivers behind the initiative.

Production will initially feature servers incorporating NVIDIA HGX B300 and NVIDIA RTX PRO 6000 Blackwell Server Edition GPUs. A second production phase, planned within fiscal year 2026 ending March 2027, will introduce servers built around Fujitsu's proprietary FUJITSU-MONAKA processor, which applies confidential computing technology for enhanced protection against data security threats.

The Kasashima Plant will operate an integrated domestic production system encompassing printed circuit board manufacturing through to complete device assembly, beginning in June and March 2026 respectively. Fujitsu cited its experience producing the Fugaku supercomputer as central to the plant's quality and reliability credentials.

Fujitsu will expand its collaboration with Super Micro Computer to deliver planning, development, manufacturing, sales and maintenance services across the AI server range. Products are targeted at deployment across both Japanese and European markets, with the domestic production model intended to ensure full transparency of traceability and operational sovereignty for customers in regulated sectors.

Fujitsu Limited reported consolidated revenues of 3.6 trillion yen (€1.98 billion) for the fiscal year ended March 2025 and employs approximately 113,000 people globally.
