Preparation for natural disasters, including risks
arising from climate change

Climate change has been increasing the risks of natural disasters. Our company has incorporated the “Earthquake Early Warning System,” which instructs all train drivers to make an emergency stop in the event of an earthquake, along with the “Disaster Prevention Information System,” which collects and monitors weather information (including rainfall, wind speed, and earthquakes) and other information that may affect railway lines, such as river water levels.
Furthermore, we have posted tsunami hazard maps, evacuation site maps, and evacuation routes at train stations located in evacuation zones (tsunami inundation areas) designated by Osaka and Wakayama Prefectures, and have installed tsunami evacuation signs to guide customers to a safe area before the arrival of tsunamis, in the event that trains stop between stations.
