Ascoe Partners Inc. (Location: Minato-ku, Tokyo; Representative Director: Hideyuki Yasui; hereinafter referred to as Ascoe Partners) has developed "Navitron," a navigation system designed to clearly guide users through administrative procedures for municipalities and other government bodies, tailored to their specific situations. Navitron is a procedure guidance system for municipalities that integrates Ascoe's administrative procedure guidance "egNavi Engine" with "NVIDIA Nemotron-Nano-9B-v2-Japanese," a Japanese-language SLM operating on NVIDIA DGX Spark provided by NVIDIA. A key feature of Navitron is that the AI does not make independent judgments about regulations. Instead, the egNavi Engine organizes candidate procedures based on structured regulatory information and decision logic it holds, and the AI then supplements and summarizes these results in an easy-to-understand manner. By having Nemotron-Nano-9B-v2-Japanese supplement and summarize the judgment results and on-screen status in natural Japanese, it realizes a guidance experience that is easy for residents to understand and for staff to explain. Furthermore, by operating within an inference environment built on NVIDIA DGX Spark, it is designed to be completed within an on-premises environment inside the municipality's building or a designated facility, without sending personal information or input content to external AI services in the cloud. This makes it easier to consider the introduction of procedure guidance utilizing generative AI even in administrative fields where personal information protection and security requirements are stringent. Background of Development Administrative procedures in municipalities vary by target person, conditions, required documents, and application destination depending on the system, making it difficult for residents to grasp the procedures they need. While expectations are high for the use of generative AI, careful consideration is required in the administrative fiel
