1. Workplace Employees’ Health Insurance (Kenko Hoken)
Employees working qualifying hours at companies in Japan are enrolled by their employer in Employees' Health Insurance. Note that the everyday conversational term "Shakai Hoken" (社会保険) in Japan often encompasses health insurance, pension, and related statutory insurance together.
2. Municipal National Health Insurance (Kokumin Kenko Hoken)
Foreign residents residing long-term in Japan who are not covered by an employer's health insurance scheme (such as self-employed individuals, students, or non-qualifying part-time workers) must register for National Health Insurance at their local municipal office.
3. Enrollment Channels and Status Updates
Workplace insurance is processed internally through your employer's HR department. Municipal health insurance requires visiting your local City Hall or Ward Office resident services counter within statutory notification periods.
4. Dependant Eligibility and Household Circumstances
Enrolling family members or dependants requires verification of relationship, residency, and income thresholds under applicable insurance rules. Requirements differ between workplace health insurance associations and municipal schemes.
5. Current My Number Health Insurance Usage and Eligibility Certificates
Under Japanese Digital Agency guidelines, existing old-format health insurance paper/plastic cards expired by December 1, 2025. From December 2, 2025 onward, medical eligibility is confirmed using a registered My Number Card or an official Certificate of Eligibility (資格確認書) issued by your insurer for those without a registered card.
6. Health Insurance Steps After Starting, Leaving, or Changing Jobs
When changing jobs or leaving an employer, you must return your previous workplace insurance credentials or transition to another coverage scheme (such as National Health Insurance or voluntary continuation) within required administrative deadlines.
