Additionally, instances of train derailments due to various causes—ranging from natural disasters like earthquakes and typhoons to human error and technical malfunctions—have led to injuries and occasional fatalities.
The system has also grappled with challenges such as extreme overcrowding during peak hours, leading to health concerns among passengers and occasional accidents. Instances of emergency braking malfunctions, fires breaking out on trains or in stations due to electrical faults, and other reasons have caused disruptions, evacuations, and service interruptions.
Despite these incidents, Japan rail system continues to prioritize safety measures, constantly refining protocols and infrastructure to uphold the high standards of its railway network.
