Column Finance and the Social Security System 2019.02.08
Every year, the government is obligated to conduct a survey of karoshi due to the Karoshi Prevention Measures Act. As mentioned in Column No. 94, karoshi literally means "death from overwork" and can be broken down into "ka," which means over, "ro," which means work, and "shi," which means death. The law classifies deaths due to an excessive work burden into two categories: deaths caused by cerebrovascular disease or heart disease, and suicides caused by psychiatric disorders.
In October 2018, the government released statistics regarding karoshi cases in 2017. As shown in Figure 1, the number of cases credited to cerebrovascular disease or heart disease caused by work and the number of deaths among them have decreased since 2010. However, the number of psychiatric disorder cases and suicides continues to increase .
Figure 3 shows the percentage of workers with more than 60 working hours a week at the end of the month, when work tends to increase. As this is one of the indicators of karoshi, the government is aiming to reduce it to 5% or less by 2020.
