Karoshi (Brain/Heart Disease, Depression)

lKaroshi usually has lifestyle diseases, such as hypertension, diabetes and hypercholesterolemia, and depression in its background.


Previously, these diseases where thought to be “Private Disease” and each employee had their “Own Responsibility” for their disease.



lRecently, it is thought that these diseases are in some part a “Company’s Responsibility”.


The responsibility of companies and managers are imposed because some lifestyle diseases can be found in a health check-up and also, “Overtime Working” is an important factor in this issue.



l Companies have to care about their employees’ health problems which are not directly caused by their work but may have close relationship with their work.



l Companies have to know about their employees’ health situations and excessive working hours.
