Fujitsu Provides Core Business System for Real-time Management of Maritime Self-Defense Force Logistics

May 26, 2026 Fujitsu Limited

Fujitsu has developed and implemented a core business system that allows for real-time management of all logistics information—including parts supply, ammunition, pharmaceuticals, and food—required for the operations and maintenance of assets used by approximately 45,000 personnel of the Japan Maritime Self-Defense Force (JMSDF). The system was provided in May 2026.

By centralizing data on the vast array of items handled by the JMSDF, the system enables real-time visualization of all logistics information. This facilitates the planning of procurement, maintenance, and replenishment, improves overall operational efficiency through data-driven supply and demand forecasting, and enables faster decision-making, thereby contributing to the strengthening of Japan's defense and sustained combat capabilities.

### Overview

Given the recent international situation and ongoing discussions regarding the revision of Japan's fundamental foreign and security policies (as outlined in the three security-related documents), the environment surrounding the JMSDF is changing rapidly. Strengthening sustained combat capability in contingencies is expected to become increasingly important. Under these circumstances, the missions of the JMSDF are becoming more complex and diversified, requiring a sustainable system capable of responding immediately to any situation with limited resources. In response to the JMSDF's goal of transforming into a data-driven organization for rapid and optimal decision-making, Fujitsu has built and deployed this core business system.

With this system, the JMSDF can centrally manage various logistics information, such as parts, ammunition, pharmaceuticals, and food across naval vessels, bases, and supply hubs nationwide. This allows commanders to grasp information necessary for mission execution in real-time and efficiently, enabling rapid decision-making.

This system is based on SAP's ERP solution, "S/4HANA®," and utilizes the "Defense & Security solution," which has a track record of use in dozens of countries. As this is the first introduction of an SAP ERP solution in a central government agency, Fujitsu has utilized the practical knowledge gained from its company-wide ERP renewal project to support the smooth construction and operation of this system, which manages an enormous volume of logistics data.

Fujitsu will continue to promote the stable operation and continuous functional improvement of this system, contributing to Japan's security by supporting the refinement of supply and demand forecasting for logistics handled by the JMSDF.

### Comment from Yoshiro Horikawa, President and Representative Director, SAP Japan Co., Ltd.

"We sincerely celebrate the launch of this system. We hope that this system will contribute to the sophistication of the logistics system of the Japan Maritime Self-Defense Force and to the stable execution of their missions."

### Comment from Takahito Tokita, President and CEO, Fujitsu Limited

"With the cooperation of the Japan Maritime Self-Defense Force and SAP, we have reached the launch of a core business system capable of managing all logistics information in real-time. I am grateful to everyone involved. This is the first SAP ERP implementation in a central government agency and a large-scale system managing a vast number of items, and I feel a great responsibility in being involved in such a system. Fujitsu is a technology company that has been involved in security not only in Japan but also overseas for many years. In a situation where technology is indispensable to security, including AI, we will continue to make efforts to contribute even more to Japan's security."

### Comment from Tsuneo Hayashi, Corporate Executive Officer, SEVP, CEO of Public Business, Fujitsu Limited

"In recent years, as Japan's security environment has changed significantly, the importance of data management, such as rapid and accurate decision-making, has been increasing. I believe that building a data foundation that can visualize and manage all logistics information of the Japan Maritime Self-Defense Force in real-time in this project is an important step that contributes to data-driven organizational management. Furthermore, based on the knowledge gained from this system, we are looking into expanding it to other agencies within the Ministry of Defense and other government offices, contributing to the sophistication of data utilization in a wider range of areas. Fujitsu will continue to support the stable operation of this system and the efficiency and rapid decision-making of the overall operations."
