How Does the Annual Health Checkup in Japan Work?

Employers in Japan are legally required to provide an annual health checkup in Japan (kenko shindan, 健康診断) to their employees. If you're covered by National Health Insurance instead - self-employed, between jobs, or otherwise not on an employer plan - your municipality also offers checkups for NHI members, though the specifics (what's covered, how to book, whether there's a fee) vary by ward, so check with your ward office directly. Either version is a screening visit: it checks a set of standard measurements and flags anything outside the normal range. It is not a treatment appointment, and if something comes back abnormal, the next step is a separate visit to a doctor about it.

If you're enrolled in Employees' Health Insurance (shakai hoken, 社会保険) through your job, your employer is legally required to provide you with an annual health checkup. In most companies this means HR books a time slot at a clinic or a designated screening center and tells you when to show up - you generally don't need to arrange it yourself. What's included in the standard checkup can vary somewhat by employer and provider, but it's built around routine screening measurements rather than a full diagnostic workup.

If you're on National Health Insurance (kokumin kenko hoken, 国民健康保険) rather than an employer plan, there's no HR department scheduling anything for you. Municipalities offer health checkups for NHI members, but the details - eligibility, cost, how to sign up, what's included - vary by ward. Your ward office is the right place to ask, and it's worth asking early in the year since these programs often run on a set schedule or have a limited window.

Beyond the standard annual checkup, many hospitals and clinics offer 人間ドック (ningen dock) - a more comprehensive health screening that goes further than the basic version. It's optional and self-pay, not something your employer or insurance covers as part of the standard obligation. Scope, what's tested, and cost vary by provider, so if you're considering one, ask a clinic directly what it includes rather than assuming it matches what a colleague or friend described.
