HPE (Hewlett-Packard Enterprise Japan, Headquarters: Koto-ku, Tokyo, Managing Director and President: Hirokazu Mochizuki) announced that Miyazaki Prefecture has built an on-premises environment using HPE ProLiant servers running the private version of GBase provided by Sparticle Inc. as a private generative AI platform exclusively for internal government use, and has begun utilizing it for administrative tasks.
Miyazaki Prefecture consists of 26 municipalities with a population of approximately 1.06 million. It has an industrial structure where agriculture and livestock are core, and food processing, manufacturing, tourism, and services support the regional economy, while government, medical, and welfare services sustain regional operations. Under the "Miyazaki Prefecture Digitalization Promotion Plan - Miyazaki DX Plan (2024–2027)," the prefecture places top priority on the safety and reliability required as a foundation for administrative services. It is advancing the sophistication of administrative operations using digital technology, proceeding with initiatives to utilize on-premises generative AI for municipal tasks such as payroll, travel expenses, and accounting administration.
Since municipal tasks routinely handle highly confidential information, the utilization of generative AI requires a design that involves no external data leakage and operations premised on strict information management. Miyazaki Prefecture has adopted a policy of introducing an internal on-premises generative AI, and will gradually expand the target tasks and scope of use while thoroughly verifying safety and operational aspects. Operating in compliance with the generative AI policy formulated by the prefecture, this environment was adopted as a foundation to steadily advance the efficiency and sophistication of administrative tasks while securing residents' trust by adhering strictly to information security.
Hirohito Nakanishi, Principal of the Digital Strategy Promotion Team, Digital Promotion Division, General Policy Department, Miyazaki Prefecture, stated as follows:
"Miyazaki Prefecture is developing a local LLM environment as a foundation to safely share administrative knowledge and support staff duties. By adopting a flexible configuration compatible with open generative AI technologies, this system is positioned as a platform that can adapt to future technological advancements. Even in the task of checking application contents, which involves many documents and requires high-level judgment, this system supports the professional decisions of the staff in charge, contributing to faster responses and reduced workloads, thereby achieving improved administrative services. As future initiatives, we are expanding and strengthening the system toward automating responses to inquiries at the disaster countermeasures headquarters via a 'Disaster Response AI Chatbot for Disaster Responders' and an 'AI Pharmacist' that supports inquiries regarding drug usage from doctors and others."
The maintenance and management of this system in Miyazaki Prefecture are handled by Minami-Nihon Network Co., Ltd. It is built as a local LLM environment utilizing the private version of GBase provided by Sparticle Inc., based on the HPE ProLiant DL385 Gen11 equipped with NVIDIA high-performance accelerators. The local LLM, a knowledge base for safely sharing administrative knowledge, utilizes RAG (Retrieval-Augmented Generation) and Agent mechanisms to refer to official documents and operational manuals regarding application procedures and administrative systems on an as-needed basis, supporting staff duties via a chatbot. With this design, the AI provides answers based on foundational administrative information without making independent judgments or learning on its own. Furthermore, strict management ensures that personally identifiable information is excluded from the AI's processing scope.
Tatsuya Kaneda, President and Representative Director of Sparticle Inc., stated as follows:
"We are delighted that Miyazaki Prefecture has adopted the private version of GBase. We believe that the prefecture's initiative holds great significance in positioning generative AI not merely as an efficiency tool, but as a foundation for safely sharing administrative knowledge and supporting staff duties. In particular, the fact that they are utilizing generative AI in a practical manner, premised on operations in an on-premises environment with information security as the top priority, provides important insights for other municipalities. Sparticle will continue to collaborate with partner companies, including HPE, to support the use of reliable and effective generative AI that is genuinely useful in the field for municipalities and regulated sectors."
Tomoko Kato, Managing Executive Officer and General Manager of Digital Sales & Compute Business Unit, Hewlett-Packard Enterprise Japan, stated as follows:
"We are highly honored that our HPE server infrastructure has been adopted in Miyazaki Prefecture's utilization of generative AI, where information security and reliability are the top priorities. As the use of AI accelerates across Japan, we feel it is highly significant to have been involved in building this system, which will serve as a model case for future municipal DX.
