Fujitsu entered into a strategic partnership with Anthropic PBC to combine Anthropic’s advanced AI technologies with Fujitsu’s long-established industry and business expertise, as well as its capabilities in building and operating systems in mission-critical domains.
Through these efforts, Fujitsu will drive the full-scale acceleration of AI transformation for Japanese enterprises, while contributing to enhancing the safety and reliability of social infrastructure, including critical systems.
Fujitsu will first thoroughly adopt and utilize Anthropic’s AI technologies, including Claude, across its own organization. Through this hands-on use, Fujitsu will accumulate and expand practical expertise, thereby contributing to the advancement of AI transformation across Japanese enterprises and society.
Through this collaboration, Fujitsu will gain early access to Anthropic’s latest AI models and, by developing and delivering solutions that utilize these models, will provide customers with more advanced and practical AI applications.
Further, Fujitsu also possesses its own AI technologies, including the AI platform Fujitsu Kozuchi and the Takane large language model. By leveraging these alongside Anthropic’s AI, Fujitsu will control the selection, design, and integration of optimal AI solutions based on customer requirements such as data sovereignty, regulatory compliance, security, and performance, and deliver them in a secure and reliable manner.
On the premise of utilizing multiple AI systems, Fujitsu will combine Anthropic’s advanced AI with its own technologies to address diverse AI utilization needs.
In addition, Fujitsu will build on its existing initiatives toward a safe and secure AI society (AI Trust) and explore the application of its advanced technologies—including HPC and next-generation hybrid computing platforms such as quantum computing—within cutting-edge AI domains.
Through these efforts, Fujitsu will promote the social implementation of AI that ensures safety and reliability, enabling trusted use even in mission-critical domains.
Through the partnership, Fujitsu will strengthen the FDE business through utilizing Anthropic’s AI services. Fujitsu will leverage Anthropic’s Claude to strengthen and expand its Forward Deployed Engineer (FDE) model, which translates AI into tangible business value.
To strengthen cyber defense capabilities in the AI era, Fujitsu will promote enhanced cybersecurity across enterprises, critical infrastructure, and essential services.
The company aims to transition from conventional, expert-dependent cybersecurity approaches to next-generation operational models in which human expertise and AI work in tandem to enable rapid response.
In particular, Fujitsu will enable both the utilization of AI and robust cyber defense in mission-critical domains. With the advancement of AI technologies, responding to cyber defense challenges has become a major societal issue.
In collaboration with the Japanese government, we will leverage the knowledge gained to contribute to strengthening security across society as a whole.
About 100,000 Fujitsu Group employees will actively use Anthropic’s Claude to enhance and accelerate operations while validating safe and secure AI usage in practice. Specifically, Fujitsu will incorporate technologies that improve AI reliability and establish both technological and operational frameworks that ensure safety, transparency, and controllability in AI utilization.
As announced in February 2026, Fujitsu is already advancing AI-driven development platforms and working on automating large-scale system upgrade processes using AI agents based on its proprietary Takane LLM.
By combining these efforts with the use of Claude, Fujitsu aims to further enhance development productivity.
“We see the rapid evolution and growth of AI as something that must be swiftly implemented in society and translated into value creation—this is a top priority for us as a technology company,” said Takahito Tokita, representative director and CEO of Fujitsu.
“Through this collaboration, we will combine Fujitsu’s deep expertise across industries and business functions—particularly its extensive know-how in mission-critical domains—with Anthropic’s advanced AI models,” said Tokita. “In doing so, we aim to support the creation of new value across industries and realize a trustworthy, AI-driven society.”
Paul Smith, chief commercial officer of Anthropic PBC, said Fujitsu has been the technology partner to Japan’s banks, hospitals, government and critical infrastructure for decades.
“They are now deploying Claude to 100,000 of their own employees and building a 1,000-person engineering team to bring it to their customers,” said Smith.
