English summary	Kumamoto City, operating a railway under the Railway Act, received an administrative guidance from the Kyushu Transport Bureau on January 22, 2025, based on safety audits conducted on September 20, 2024. The city submitted an interim improvement report on October 21, 2024, and has been working towards finalizing corrective actions. However, incidents continued, including a derailment on December 31, 2024, between Kumamoto Castle/City Hall and Hanabatake-cho stations, believed to be caused by gauge widening. Post-accident inspections revealed new gauge widening near the site, leading to service suspensions and impacting users. The bureau urges the city to re-assess the safety of all tracks, review current maintenance practices, investigate causes including underlying factors, and establish measures to prevent recurrence, ensuring proper safety management. The city is also required to report promptly on measures implemented. This guidance is issued by the Kyushu Transport Bureau.
Original Japanese text	貴局に対しては、令和６年９月２０日付け九運鉄監第１９号にて保安監査の実施結果に基づく改善指示を行ったところである。貴局から令和６年１０月２１日付け熊交運発第０００２５７号「保安監査結果に対する改善策について（中間報告）」により改善報告（中間報告）が提出され、現在も最終報告に向けて改善に取組んでいるところであるが、その後もインシデント事象を発生させるとともに、「年末年始の輸送等に関する安全総点検」の期間中である令和６年１２月３１日には、熊本城・市役所前停留場～花畑町停留場間において軌間拡大によるものと考えられる車両脱線事故を発生させた。更に、同事故後に、軌道の整備を行ったにもかかわらず、事故現場付近で新たに軌間が拡大している箇所が確認され、整備のための運休が発生する等、利用者に影響を与える事象が発生していることは、誠に遺憾である。ついては、貴局の全線の軌道について、安全性を再確認し、現在の軌道の維持管理の方法について再度検証を行うとともに、背後要因を含めた原因究明と再発防止対策を策定することにより輸送の安全に係る業務を適切に実施されたい。また、講じた措置等については、速やかに報告されたい。【九州運輸局】

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.
