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.

4. 22 January 2025 Administrative Guidance

Company	熊本市
Law	Railway Business Act
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. Despite these efforts, incidents continued, including a derailment on December 31, 2024, between Kumamoto Castle/City Hall and Hanabatake-cho stations, believed to be caused by track gauge widening.

The city is also required to promptly report on measures taken.
