English summary	On January 16, 2026, at approximately 3:50 AM, a power outage at Tamachi Substation caused prolonged service suspensions on the Yamanote Line, Keihin-Tohoku Line, and Tokaido Line, among others. The incident also led to numerous passengers experiencing health issues after the temporary resumption of service on the Keihin-Tohoku Line. The cause was initially reported as a power outage due to nighttime construction work. The Kanto Transport Bureau has warned JR East to investigate the root causes, including underlying factors, and to take measures to prevent recurrence, ensuring the safety and stability of railway transportation. JR East is also instructed to verify the appropriateness of recovery operations, the decision to resume service, passenger rescue efforts, and information dissemination, and to report these measures in writing promptly.
Original Japanese text	鉄道の安全・安定輸送の確保については、機会あるごとに注意喚起してきたところであるが、令和８年１月１６日３時５０分頃に発生した田町変電所の停電により、山手線、京浜東北線、東海道線等において長時間にわたり運転を休止する輸送障害を発生させるとともに、一時運転再開した京浜東北線の乗客に多数の体調不良者を発生させたことは誠に遺憾である。本輸送障害の原因については、夜間の工事作業を起因とする停電との速報を受けているところであるが、背後要因を含めて原因の究明を行い、再発防止策のための措置を講じ、鉄道の安全・安定輸送の確保に万全を期すよう警告する。また、復旧作業及び運転再開の判断の妥当性並びに乗客救済及び利用者への情報提供についても検証を行うとともに、その検証結果を踏まえ、適切な措置を講じられたい。なお、講じた措置等については、文章により速やかに報告されたい。【関東運輸局】

4. 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.
