5. 30 October 2024 Administrative Guidance

Company	東日本旅客鉄道株式会社
Law	Railway Business Act
Summary	Following the nationwide directive issued on September 12, 2024, to railway operators for emergency inspections of train wheel axles, East Japan Railway Company reported that between 2008 and 2017, it used wheel axles that deviated from regulations and altered work records. An audit by the Ministry of Land, Infrastructure, Transport and Tourism confirmed these facts. Such record modifications are considered to fundamentally undermine safety mechanisms and are unacceptable. The ministry has shared safety information with all railway operators and expressed regret that these issues were not reported promptly. The company is advised to review its safety management system, ensure proper information sharing, and establish mechanisms for immediate reporting of similar issues.
