Yoro Railway Co., Ltd. was issued administrative guidance on December 17, 2025, for multiple violations related to railway operation practices. These included operating trains with staff not holding the required driver licenses, allowing staff without proper identification to enter the crew room without justification, non-licensed staff handling train doors contrary to regulations, improper management of keys for crew room access, and insufficient training and supervision of staff, which led to violations of the Railway Business Act and related regulations.

On May 12, 2025, it was discovered that a train driver belonging to Yoro Railway Co., Ltd. had operated a train without properly conducting alcohol breath tests using an alcohol detector before and after duty, as mandated by Article 11 of the Driver Handling Rules. A safety audit conducted on May 13, 2025, identified deficiencies requiring corrective action. The company was instructed to verify the appropriateness of operational methods, implementation status, and management of alcohol testing, investigate the root causes, and develop measures to prevent recurrence, ensuring the safety of railway transportation. The company is required to report on the measures taken by July 14, 2025. It was confirmed that multiple assistant conductors did not perform alcohol tests on a specific driver but recorded no alcohol detection, and the management department was unaware of the situation. The company must ensure proper alcohol testing, accurate record-keeping, re-educate staff on safety and compliance, and strengthen safety management systems. Failure to improve safety management may result in orders to improve business operations under the Railway Business Act. The legal basis for the order includes Article 23 of the Railway Business Act and related provisions of the Administrative Procedure Act. The source of this enforcement is the Chubu Regional Transport Bureau.
