5. Country-Specific Considerations

Cultural Aspects

• Collectivism and Social Responsibility: Japan’s Social Insurance system reflects the country’s emphasis on collective well-being. Participation is seen as a civic duty, and there is a strong cultural expectation to comply with the system.
• Employer-Employee Relationship: Employers are highly involved in managing Social Insurance for their employees, reflecting the importance of mutual trust and responsibility in Japanese workplaces.

Language Barrier

• Most documents and procedures are in Japanese. It is advisable to seek assistance from a Japanese-speaking colleague, friend, or professional service if you are not fluent.

Healthcare System

• Japan’s healthcare system is highly efficient and affordable due to the Social Insurance system. Patients typically pay only 30% of medical costs, with the rest covered by insurance.
• There are caps on out-of-pocket expenses, ensuring affordability even for major medical treatments.

Pension Portability for Foreigners

• Foreign nationals who leave Japan can apply for a Lump-Sum Withdrawal Payment (dattai ichijikin) to reclaim a portion of their pension contributions. However, this does not include the employer’s contributions.
• Japan has social security agreements with several countries (e.g., the U.S., Germany, Australia) to avoid double payments and allow pension portability.
