Fujitsu Limited has unveiled its AI-driven Modernization Service in Japan, aimed at supporting sustainable growth for businesses and organizations. The service combines Fujitsu's expertise in system integration with generative AI to automate and optimize modernization efforts, focusing on rewrite and rehost strategies.
The service leverages multiple AI models and the expertise of specialized engineers to shorten migration periods by approximately 40%. This is increasingly critical in sectors such as finance, public services, and healthcare, where frequent legal revisions demand swift adaptation. Manufacturing and distribution industries, with their complex operational requirements, also stand to benefit from the service.
The service integrates Fujitsu's proprietary AI platform, Fujitsu Kozuchi, and the Takane large language model (LLM), alongside cutting-edge AI technologies like Anthropic PBC's Claude and OpenAI's GPT. This combination, along with the expertise of Fujitsu's Modernization Meisters, facilitates rapid and high-quality modernization, supporting customers in achieving swift business transformation.
Key features of the service include AI-driven automation that comprehensively analyzes legacy data and manages it as AI-ready structured data. This approach minimizes rework and quality variations, enabling flexible adaptation to future expansions while preserving existing system assets. The service also supports large-scale code conversion, ensuring migration to maintainable and extensible Java applications.
Fujitsu's multi-AI modernization approach optimally utilizes multiple AIs, allowing customers to focus on core business transformation initiatives without the burden of selecting and managing rapidly evolving AI technologies. The service employs specialized AI agents trained on Fujitsu's extensive project data, enhancing the reproducibility and reliability of modernization efforts.
In March 2026, Fujitsu launched the Fujitsu Application Transform, an automated design document generation service, as the first phase of its AI modernization platform services. The newly launched AI-driven Modernization Service is specifically designed for modernization, with plans to provide AI service platforms that enable customers to perform modernization independently.
Fujitsu aims to support the acceleration and sustainable evolution of customers' modernization efforts through this service, contributing to rapid data-driven management decisions and enhanced competitiveness in various industries.
