Public sectors have promoted countermeasures of factories and workplaces against chemical release accidents triggered by natural disasters. In this study, we estimated the storage amount of toluene in factories and workplaces below-threshold-condition under the Pollutant Release and Transfer Register (PRTR) system in Japan. The storage in factories and workplaces operating certain industries within the manufacturing sector located in 17 cities and wards in Kyoto was discussed. As a result, it was found that there were approximately 148.9 factories and workplaces with an estimated total of approximately 13,700 kg of toluene stored. Also, it was suggested that factories and workplaces handling more than a ton of toluene annually could be located in the 11 cities and wards. Therefore, even factories and workplaces below-threshold-condition under the PRTR in Japan have the potential to cause significant damage in the event of chemical release accidents triggered by natural disasters.
