KAWASAKI, Japan, Feb 17, 2026 – (JCN Newswire via SeaPRwire.com) – Fujitsu Limited today announced the development and launch of its AI-Driven Software Development Platform, a new initiative to bring software development into the AI age and contribute to the sustainable growth of its customers and society. This platform automates the entire software development process, from requirements definition and design to implementation and integration testing. By leveraging the Takane large language model (LLM) [1] and agentic AI technology for large-scale software development developed by Fujitsu Research, the AI-Driven Software Development Platform enables AI agents to understand complex, evolving large-scale systems owned by enterprises and public organizations. The platform has multiple AI agents collaboratively execute each stage of software development, achieving full automation of the entire process without human intervention.
Fujitsu aims to use this AI-Driven Software Development Platform to carry out revisions to all 67 types of medical and government business software products provided by Fujitsu Japan Limited by the end of fiscal year 2026. The revisions are necessary due to legal and regulatory changes. From January 2026, the platform has been used in Japan for software modifications made necessary by the 2026 medical fee revisions [2]. In a PoC that updated software as per the 2024 medical fee revisions, the platform demonstrated a significant reduction in development time for one of approximately 300 change requests. Using conventional software development methods [3] the modifications would have taken three person-months. With this technology that was dramatically shortened to four hours, achieving a 100-fold increase in productivity.

By utilizing this AI-driven development platform, Fujitsu will dramatically improve the speed of software modifications necessitated by legal amendments and system changes. This will significantly reduce the burden previously required for system verification during modifications, thereby freeing up time for the planning and development of measures and services that lead to improved patient, resident, and customer services, as well as enabling customers and partners to continuously adapt to ever-changing operations and societal needs. Furthermore, Fujitsu envisions that this technology will also help customers and partners to respond to expanding IT demand and alleviate the worsening shortage of IT professionals.
In AI-driven development, Fujitsu positions AI-Ready Engineering—the process of preparing assets and knowledge to ensure AI correctly understands existing systems and achieves highly reliable automation—as crucial. With AI-Ready Engineering and the AI-Driven Software Development Platform working in tandem, Fujitsu will accelerate AI-driven software development. Fujitsu will promote a transformation in engineers’ work styles, strengthening its Forward Deployed Engineer (FDE) complement, and shifting the paradigm of software development from a conventional person-month-based approach to a customer value-based approach.

“This AI automation initiative promoted by Fujitsu is not merely about improving development efficiency; we recognize it as a significant challenge to pass on and evolve the extensive business knowledge and design philosophies cultivated by companies over many years to the next generation. In particular, the concept of providing end-to-end support, from requirements definition to design, implementation, and quality assurance, triggered by changes in laws and rules, opens up new possibilities in areas that have traditionally relied on human experience and tacit knowledge. We see great significance in AI functioning as a foundation that supports human judgment and creativity, rather than replacing it.In the manufacturing industry, challenges such as design changes, regulatory compliance, and understanding the scope of impact are becoming increasingly complex year by year. Fujitsu’s approach of advancing both knowledge standardization and AI utilization in these areas offers valuable insights for enhancing the productivity and competitiveness of the entire industry.Kawasaki Heavy Industries sincerely hopes that this initiative will be a crucial step in driving the transformation of Japanese manufacturing and a wide range of other industries, and we wholeheartedly support its further development.”
Yasushi Matsuda, President and CEO, Kewpie Digital Innovation Co., Ltd.
“Systems have become increasingly complex through years of operation and often now require significant maintenance effort. While the introduction of generative AI has improved auditing efficiency, its accuracy remains insufficient for reliable practical application. Amidst this situation, we place great expectations on “Multi-layer Quality Control,” which automatically corrects ambiguities and omissions. We are confident that this mechanism, where AI itself audits quality and autonomously repeats processes, will dramatically enhance the reliability of system development. We eagerly await its future development.”
Junichi Aruji, Managing Director, Kintetsu Information System Co., Ltd.
“The challenge of revamping existing systems has long been a significant one for engineers. Fujitsu’s AI-Driven Software Development Platform has the potential to dramatically transform the labor previously involved in understanding complex laws and regulations, analyzing vast historical assets, and grasping the tacit knowledge of the field.What is particularly noteworthy is the AI’s ability to autonomously learn “human intelligence,” thereby dramatically enhancing the accuracy of requirements definition. Furthermore, it can complete everything from program structure analysis and standardization to the extensive testing phase with incredible speed and comprehensiveness. This makes it possible to deliver high-quality products in a short period.As the role of AI expands and frees people from routine tasks, engineers can focus on more creative activities.

Masahiro Niimi, Managing Executive Officer, Head of Information Systems Management Division, CISO, Sakura KCS Corporation
“I believe Fujitsu Limited’s AI-driven development framework has the potential to become the ‘new paradigm of system development.’ It cannot be achieved simply by feeding existing code or design information into AI, and while there are various hurdles, such as converting documentation to Markdown and establishing test environments, overcoming these hurdles can lead to solving traditional system development challenges (like QCD).What particularly caught my attention is not just improvements in the development process, but what comes after generative AI, i.e., the incorporation of detailed specifications and code (logic). I see tremendous potential here as a solution to the greatest challenge: visualizing and transferring the tacit knowledge of veteran software engineers’ that is traditionally missing from documentation. We expect generative AI to act as an advisor for less experienced software engineers, readily answering questions anytime, thereby dramatically advancing know-how transfer to the next generation. On the other hand, this mechanism also has the potential to dramatically change the traditional SI business model, and we are watching future developments closely.”
Takao Kazama, Executive Officer, Group Companies and Accounting & Finance, The Shizuoka Shimbun and Shizuoka Broadcasting Co., Ltd.
“This initiative for complete automation of application development and maintenance represents a highly valuable transformation for our company.
