Fujitsu signed a strategic partnership with Anthropic on May 27, deploying Claude across its entire 100,000-person workforce while building a dedicated 1,000-person engineering team to sell Anthropic's models into Japan's most sensitive sectors, government, finance, healthcare, defense, and critical infrastructure. The deal is one of the largest enterprise AI commitments in the Japanese market, according to Anthropic chief commercial officer Paul Smith. "The institutions that anchor Japanese society, its banks, its hospitals, its government, its critical infrastructure, hold AI to the highest standard," Smith said.
"Fujitsu has been the technology partner to those institutions for decades, and they are now deploying Claude to 100,000 of their own employees."
Fujitsu is positioning itself as "Customer Zero", the Japanese tech giant will run Anthropic's models internally first, validate safety and reliability, then package the learnings for clients. The company said it will combine Claude with its own AI stack, including the Fujitsu Kozuchi AI platform and the Takane LLM, to deliver solutions tailored to customer requirements around data sovereignty, regulatory compliance, and security. The partnership centers on expanding Fujitsu's Forward Deployed Engineer (FDE) model, which embeds engineers directly with customers to translate AI capabilities into business outcomes. Fujitsu has already accumulated FDE expertise through collaborations with Palantir and other advanced technology partners.
"We will immediately apply the knowledge gained from this transformation to customers, enabling not just AI implementation but full business transformation," said Yoshinami Takahashi, Fujitsu's corporate executive officer and COO in charge of solution services. "This will accelerate structural transformation of business and enable a shift toward high-value-added business models." On the cybersecurity front, Fujitsu plans to move from traditional, expert-dependent security models to AI-assisted operations, working with the Japanese government to apply lessons learned across wider society.
Fujitsu CEO Takahito Tokita described AI adoption as a top priority for the company. "We see the rapid evolution and growth of AI as something that must be swiftly implemented in society and translated into value creation," Tokita said. The deal builds on Fujitsu's existing AI work. The company announced in February 2026 that it was advancing AI-driven development platforms and automating large-scale system upgrades using AI agents based on its Takane LLM. With early access to Anthropic's latest models, Fujitsu now aims to layer Claude on top of those efforts.
Fujitsu reported consolidated revenues of 3.5 trillion yen ($23 billion) for the fiscal year ended March 31, 2026, and remains the top digital services company in Japan by market share.
