On the 18th of January, JR East announced that it would impose internal penalties on President Yoichi Kise, Vice President Chiharu Wataru, and two other executives due to a series of transport troubles that have adversely affected the company's reputation. The company's management cited a failure to adequately fulfill their supervisory responsibilities as the reason for the sanctions. President Kise will forfeit 20% of his salary for one month, while Vice President Wataru will return 10% of his salary for the same duration. The two other executives responsible for safety planning have received written reprimands.

The operational troubles began on January 16 when a mistake during night construction work caused a blackout that halted services on the Yamanote Line and Keihin-Tohoku Line for more than eight hours, impacting approximately 673,000 commuters. Following that incident, further issues arose, including power outages on the Joban Line and Utsunomiya Line due to overhead wire cuts and a significant escalator fire at Hatchobori Station on the Keiyo Line. Each of these incidents led to considerable disruptions in the transportation network.

These incidents have sparked discussions around the adequacy of JR East's management protocols and the urgency for improvements in their operational safety measures. The penalties imposed reflect the company's commitment to accountability and may serve as a warning to other executives to prioritize infrastructure and operational safety to regain customer trust and confidence within the metropolitan transport system.
