Fujitsu and Anthropic Announce Strategic Partnership Agreement

May 27, 2026
Fujitsu Limited

Fujitsu announced a strategic partnership with Anthropic PBC (hereinafter 'Anthropic') on May 27, 2026. Through this collaboration, Fujitsu will become a strategic partner of Anthropic, combining Anthropic's advanced AI technology with Fujitsu's long-standing industry knowledge, business expertise, and mission-critical system construction and operation capabilities. This move is intended to accelerate the digital transformation of Japanese companies while enhancing the security and reliability of critical infrastructure and social foundations.

Fujitsu will first comprehensively utilize Anthropic's AI, including 'Claude,' internally to accumulate and expand know-how, thereby promoting AI transformation within Japanese companies and society. Recognizing its responsibility as a company deeply involved in critical infrastructure in Japan and globally, Fujitsu will also strengthen security for the AI era. Through this partnership, Fujitsu will gain early access to Anthropic's latest AI models and provide more advanced and practical AI-driven solutions to its customers.

Fujitsu also possesses proprietary AI technologies, such as the AI platform 'Fujitsu Kozuchi' and the large language model 'Takane.' By controlling optimal AI selection, design, and integration based on customer requirements regarding data sovereignty, regulatory compliance, security, and performance, Fujitsu delivers solutions that can be used with peace of mind. By combining Anthropic's advanced AI with its own capabilities, Fujitsu aims to meet diverse AI-related needs.

Furthermore, in addition to its ongoing efforts toward realizing a safe and secure AI society ('AI Trust'), Fujitsu will explore the application of its advanced technologies, such as HPC and next-generation hybrid computing infrastructure including quantum computers, to the AI sector. This will promote the implementation of safe and reliable AI in society, even in mission-critical areas.

Key Initiatives of the Collaboration:

1. Strengthening the FDE Business with Anthropic
Fujitsu will leverage Anthropic's 'Claude' to strengthen and expand its Forward Deployed Engineer (FDE) model, which ensures that AI leads to tangible value creation. Drawing on practical FDE knowledge gained through strategic partnerships with advanced technology partners like Palantir Technologies Inc., Fujitsu delivers rapid AI solution design, implementation, and adoption. By integrating 'Claude' into this model, Fujitsu will realize AI applications that are directly tied to business value, based on close customer collaboration and industry-specific insights.

2. Evolution of Cybersecurity
To enhance cyber defense in the AI era, Fujitsu will promote improvements in cyber defenses for enterprises, critical infrastructure, and essential services. The goal is to evolve from human-centric, expertise-dependent cyber defense models to next-generation security operation models where humans and AI collaborate for rapid response. This includes achieving both AI utilization and defense in mission-critical areas. Recognizing that responding to cyber threats associated with AI advancement is a major societal issue, Fujitsu will collaborate with the Japanese government to contribute to the strengthening of overall societal security.

3. Establishing and Expanding Internal AI Utilization Models
Fujitsu's entire group workforce (approximately 100,000 employees) will utilize Anthropic's 'Claude' to optimize and accelerate their operations while practically validating how to use AI safely and securely. Specifically, by incorporating Fujitsu's technology for enhancing AI reliability, the company will establish both technical and operational foundations that ensure safety, transparency, and control. These insights and standardized approaches will be shared with customers to promote reliable AI utilization among Japanese enterprises. As announced in February 2026, Fujitsu has been automating large-scale system update processes using 'Takane' AI agents, and by mastering 'Claude,' the company aims to further accelerate development...
