Yes, Japan has experienced several train derailments throughout its long railway history, despite its reputation for world-leading safety. While the high-speed Shinkansen (Bullet Train) has a nearly perfect safety record with zero passenger fatalities due to derailments in over 60 years of operation, conventional lines have seen tragic incidents. The most notorious in recent memory is the Amagasaki Rail Crash in 2005, where a commuter train derailed and struck an apartment building, resulting in 107 deaths. Another significant event occurred in 2004 when a Shinkansen train derailed during the Mid-Niigata Earthquake; notably, there were no injuries, proving the effectiveness of Japan's early earthquake detection systems. These incidents have historically led to massive overhauls in safety technology, including the mandatory installation of Automatic Train Stop (ATS) systems and enhanced "black box" recorders across all networks to ensure that the lessons from every derailment are used to prevent the next one.
