Measures for Rainfall
To prevent landslides due to rainfall, we are systematically implementing disaster prevention measures along slopes and other areas throughout the railway network.
In recent years, rainfall disasters have become more severe as well as more frequent, and localized heavy rains are on the rise. In response, in June 2023, we introduced operational regulations using precipitation radar on conventional lines. On Shinkansen as well, to prepare for the increased risk of disasters due to record-breaking rainfall and other future anticipated events, since FY2022.3 we have been proceeding with rainfall disaster prevention work. In addition, in 2020, we introduced new regulations requiring detailed assessment of rainfall volumes using weather radar and the temporary suspension of Shinkansen operations in the event of heavy rain to confirm safety.
