Abstract
This study evaluated the impact of increased heavy rainfall caused by global warming on natural disasters, train derailments caused by rainfall-induced disasters, and bridge washouts on Japanese railway from 1966 to 2023. The results are summarized as be follows: Heavy rainfall increased in this period. Natural disasters and train derailments caused by rainfall-induced disasters decreased before the 1980s and leveled off after the 1990s. The decrease in natural disasters is considered to the effect of the implementation of hard countermeasures, and the decrease in train derailments is considered to the effect of the improvement of train operation control methods against rainfall and the implementation of hard countermeasures. The fact that the number of natural disasters has leveled off without decreasing after the 1990s is considered to the result of the increase in heavy rainfall caused by global warming. Bridge washouts leveled off before the 1980s and increased after the1990s. The fact that the number of bridge washouts has leveled off despite the increase in heavy rainfall is considered to the effects of river improvement and the number of bridge washouts has increased after the 1990s is considered to the result of the increase in heavy rainfall caused by global warming.
