FUJITSU Limited has announced the launch of an artificial intelligence-driven platform designed to usher coding and application engineering into the AI era, positioning the initiative as a catalyst for innovation and sustainable growth among its customers and across society.

“This platform automates the entire software development process — from requirements definition and design to implementation and integration testing,” Fujitsu said in a news release.

The company explained that the platform enables AI agents to understand complex, evolving, large-scale systems owned by enterprises and public organisations. It uses the Takane large language model (LLM) and agentic AI technology for large-scale software development developed by Fujitsu Research.

“The platform has multiple AI agents collaboratively execute each stage of software development, achieving full automation of the entire process without human intervention,” the company said, adding that it aims to use the 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”.

According to the company, 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,” Fujitsu said, pointing out that in a proof of concept 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, 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,” Fujitsu stated.

The company said that by utilising this AI-driven development platform it 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,” Fujitsu explained.

The company additionally said it envisions that this technology will also help customers and partners to respond to expanding information technology (IT) demand, and alleviate the worsening shortage of IT professionals.

According to Fujitsu, it plans to expand the application of the AI-driven software development platform to a wide range of sectors, including finance, manufacturing, retail, and public services, by the end of fiscal year 2026.

Additionally, Fujitsu said it will begin offering this service to customers and partner companies to enable them to rapidly and flexibly develop systems that adapt to changes in their business environments.
