Fujitsu unveils an AI-Driven Software Development Platform that automates the entire software life cycle—from requirements to integration testing—using its Takane LLM and agentic AI technology developed by Fujitsu Research.

The platform leverages proprietary AI and large language models to automate all stages of development, including requirements, design, coding, testing, and regulatory updates, with the aim of full automation and rapid adaptation to changing laws and business rules.

Internal pilots report dramatic productivity gains, with tasks once costing months now completed in hours, illustrating roughly 100x productivity improvements in some cases.

The approach targets three structural challenges in system development: talent shortages in IT, rising technical debt, and misaligned revenue models under traditional time-and-materials arrangements.

Endorsers across sectors—IDC Japan, industry partners, and major tech players—highlight productivity gains, potential industry-wide transformation, and the ability to preserve tacit knowledge through AI-assisted processes.

The platform is expected to accelerate software changes in response to legal amendments and system updates, reduce verification burden, and free time for planning and service enhancements that improve patient, resident, or customer experiences.

AI-Ready Engineering is emphasized as critical to prepare assets and knowledge, ensuring AI can reliably understand existing systems and automate processes, enabling a shift to value-based development.

The initiative is framed as both a technological breakthrough and a strategic transformation of Fujitsu’s systems-integration business, aiming to set a new productivity benchmark and drive broader societal impact.

Fujitsu plans to revise 67 types of medical and government software by the end of FY2026 to comply with regulatory changes, building on a proof of concept that reduced a 3 person-month modification to 4 hours in 2024.

The press release notes Takane LLM (co-developed with Cohere), medical fee revisions, and traditional development methods, while affirming Fujitsu’s commitment to SDGs.

Executives describe this shift as an AI-driven paradigm shift in system development, redefining how software is built and aligning AI-ready transformation with Fujitsu’s value-creating mission.

The announcement envisions transforming software development into an AI-driven model to address IT labor shortages and legacy-system complexity, with a focus on safety and domain-specific language for Japan.
