As of April 2025, the Marubeni I-DIGIO Group has transitioned to a new business segment management structure across the entire organization. This marks a significant step forward in our ongoing evolution—from a solution and product sales-oriented business to a value-driven approach that places our customers at the heart of everything we do. In the area of distribution and industrial solutions, with ERP at the core, we are committed to delivering comprehensive, one-stop services for system development. Our goal is to respond with precision and flexibility to the diverse needs of our clients. Through our recent investment in Nakamoto & Associates, we are enhancing our product lineup and striving to provide even higher-quality services. By supporting ERP implementation, we aim to address a wide range of IT-related challenges and actively assist in the development of business systems and the operations of information systems departments.

We would like to express our sincere gratitude for your continued support. My name is Tomohisa Kiyose, COO of Nakamoto & Associates. Since our founding in 1993, we have specialized exclusively in Oracle products, delivering ERP implementation services both domestically and to overseas subsidiaries, thereby expanding our business on a global scale. We are pleased to announce that, with the recent capital participation from Marubeni I-DIGIO, we have further strengthened our corporate structure and foundation. This strategic partnership enables us to provide even more stable services and take on larger, more ambitious challenges. With this robust new backing, we are committed to growing stronger and reaching greater heights together with our valued clients and partners, including Oracle Corporation. We look forward to your continued support and partnership as we embark on this exciting new chapter.
