Fujitsu signs strategic partnership with Anthropic

In sectors that underpin society—particularly government, finance, healthcare, defense, and critical infrastructure—it is essential to be able to utilize advanced AI with confidence and reliability. Fujitsu will first thoroughly adopt and utilize Anthropic’s AI technologies, including Claude, across its own organization. Furthermore, Fujitsu also possesses its own AI technologies, including the AI platform Fujitsu Kozuchi and the Takane large language model (LLM) [1]. 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. Through these efforts, Fujitsu will promote the social implementation of AI that ensures safety and reliability, enabling trusted use even in mission-critical domains.

In recent years, AI has evolved beyond a tool for operational efficiency to become a foundational technology shaping corporate competitiveness and the stability of social infrastructure. At the same time, as cutting-edge AI becomes increasingly powerful, improper use may result in unintended consequences.

In sectors that underpin society—particularly government, finance, healthcare, defense, and critical infrastructure—it is essential to be able to utilize advanced AI with confidence and reliability. This requires not only implementation but also a continuous operational framework capable of delivering sustained value.

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.

As a company deeply involved in critical infrastructure in Japan and globally, Fujitsu also recognizes its responsibility to strengthen security in the AI era. 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.

Furthermore, Fujitsu also possesses its own AI technologies, including the AI platform Fujitsu Kozuchi and the Takane large language model (LLM) [1]. 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.
