Malignant neoplasmsIn recent years, malignant neoplasms have been the leading cause of death for both female and male populations in Japan. The most frequent cause of cancerous tumor related deaths has continued to be lung cancer for both men and women. As smoking and passive smoking are some of the main causes of lung cancer, the health ministry in Japan set the goal of reducing the smoking rate of adults. To minimize the risk of passive smoking, the government amended the Health Promotion Act and prohibited smoking in public facilities, offices, most restaurants, and public areas starting from April 2020. SuicideOne of the leading causes of death specific to men in Japan was suicide. In the last decade, the number of suicides committed by men in Japan remained roughly double the number of those committed by women. While close to half of the suicides in Japan were committed due to health reasons in previous years, the number of suicides owning to work-related problems has also become a serious social issue in the current Japanese society. One of the reasons behind it is said to be the working condition of employees in Japan with a severe workload. The government has been aiming to reduce working hours and overtime to improve the working conditions of workers in Japan.
