Kyndryl, a leading provider of mission-critical enterprise technology services, announced that it will support Yamaguchi Financial Group (Yamaguchi FG) in building an integrated platform for its core banking system. This will enable Yamaguchi FG's three banks—Yamaguchi Bank, Momiji Bank and Kitakyushu Bank—to operate on a shared IT infrastructure while consolidating application programs into a single source.  

This initiative will streamline group operations and support future business expansion via an IT platform that enables new financial institutions to join and begin operations quickly and efficiently.

Under the agreement, Kyndryl Japan will manage the IT infrastructure domain and support the Group's management in strengthening its foundation, while IBM Japan will support the business application domain. The initiative began in January 2026, with the new system targeted for launch in January 2029.

By operating multiple banks on a single system, Yamaguchi FG aims to enhance its IT management structure and create a framework that enables additional financial institutions to integrate into the platform seamlessly.

The new core banking system platform will integrate the operating system, middleware and common infrastructure programs, and consolidate application programs into a unified environment. This approach will improve development productivity and reduce operational costs of the core banking system.

Kyndryl Japan brings decades of experience supporting mission‑critical systems, as well as extensive expertise serving the financial services sector, including core initiatives among regional banks. Kyndryl also leverages advanced technologies, including AI, and provides comprehensive end‑to‑end capabilities across consulting, design, build and operations that will assist and facilitate Yamaguchi FG's transformation.
