Shakai Hoken is Japan's social insurance system that provides health insurance and pension benefits to workers. It is designed to ensure that employees have access to medical care and financial support during retirement or in case of disability. Employers and employees both contribute to this system, making it a shared responsibility. The system consists of two main components: health insurance and pension insurance. Health insurance covers medical expenses, while pension insurance provides income after retirement. This comprehensive approach helps maintain the well-being of the workforce and supports individuals throughout their lives.
