English summary	Kumamoto City, as a railway operator, was subject to administrative guidance from the Kyushu Transport Bureau on March 25, 2025, under the Railway Operation Regulations. This followed a vehicle collision incident near Kumamoto Castle and City Hall station on September 20, 2024, which resulted in injuries to six passengers and one driver. Prior to the incident, the operator had been repeatedly cautioned about ensuring the safety of railway transportation and had received directives to properly conduct safety-related operations, including a safety audit report numbered Kyun Tetsukan No.19. Despite these measures and ongoing efforts to improve safety, the collision occurred at around 8:31 AM, causing significant concern over public trust. The bureau emphasizes the importance of recognizing the severity of such incidents, conducting prompt cause analysis, and implementing necessary measures to prevent recurrence, thereby ensuring safe transportation. The operator is required to promptly report the cause and specific preventive actions in writing.

Company	熊本市
Law	Railway Business Act
Summary	Since January 2024, the Kumamoto City transportation bureau has been requested to investigate causes and implement measures to prevent recurrence for numerous incidents, including accidents and major incidents. Despite efforts to improve following safety audits (notably on September 20, 2024), a vehicle collision at Kumamoto Castle and City Hall station on March 25, 2025, resulted in multiple injuries. The investigation by the Japan Transport Safety Board is ongoing. In response, safety audits conducted from March 27 and April 15-18, 2025, identified new areas needing improvement, leading to further directives. These include verifying and revising driver training and knowledge verification procedures, ensuring proper vehicle abandonment protocols (such as carrying the lever handle), and confirming the accuracy and reporting of pre-operation vehicle inspections. The bureau is instructed to establish management systems for these procedures, conduct staff education, and report on measures taken by August 18, 2025. The overarching goal is to strengthen safety management systems, ensure accurate operational procedures, and prevent future incidents.

Summary	On September 20, 2024, the Kyushu Transport Bureau issued an improvement directive based on safety audits conducted on Kumamoto City's railway operations under the Railway Act. Kumamoto City submitted an interim report on October 21, 2024, detailing corrective measures, and is working towards a final report.
