In Japan, health insurance premiums are a fundamental part of the healthcare system, which is divided into two main types: Employee Health Insurance for salaried workers and National Health Insurance for self-employed, unemployed, or retired individuals. Premiums are calculated based on several factors, including income, age, and the number of dependents, ensuring that contributions are fair and reflective of one’s ability to pay. For Employee Health Insurance, premiums are typically split evenly between the employer and employee and are based on the employee’s salary. In contrast, National Health Insurance premiums are determined by the individual’s income, residence tax, and the specific municipality’s policies, with adjustments for household size and income levels. This system aims to balance the financial sustainability of healthcare services with accessibility and affordability for all residents.
