Violation

Machine-translated summary — verify against original

Between August 27 and 29, 2025, the Tohoku Transport Bureau conducted a safety audit of Yurihonjo Railway Co., Ltd. (法人番号2410001005244), headquartered in Yurihonjo City, Akita Prefecture. The audit revealed that the company did not recognize the necessity of the special general inspection of the Maesugiyama Tunnel as stipulated in Article 61 of the Track and Civil Engineering Maintenance Standards, and thus did not perform it. The company is instructed to formulate an inspection plan for the Maesugiyama Tunnel, which had not been inspected, and to record defect developments on a defect development diagram to facilitate defect recognition. Additionally, the company must review its management system to ensure proper compliance with laws and standards for future tunnel maintenance. Furthermore, it was confirmed that inspections of the vehicle roof in the critical parts and general inspections, as specified in Appendices 3 and 4 of the Vehicle Inspection Standards, were partially not conducted. The company is required to take necessary measures to ensure the proper execution and management of inspections in accordance with these standards. The guidance requests the company to report on the measures taken by March 3, 2026. The guidance emphasizes the importance of investigating the root causes of deficiencies, implementing preventive measures, and ensuring the safety of transportation operations.
