Student health insurance: in Germany it gates enrolment, in Japan it gates residence

It is not a line on the visa checklist

Insurance is usually treated as a paper for the consulate: arrange it, attach it, forget it. In two very different systems — the German and the Japanese — it works differently, and it surfaces after you arrive.

In one, you cannot become a student without it; in the other, you cannot lawfully live in the country. Both are worth knowing.

Germany: insurance comes before enrolment

Health insurance is compulsory for everyone in Germany, and it has to be proven when you enrol at the university. Not as a figure of speech: matriculation requires either a Versicherungsbescheinigung, the certificate of insurance, or a Befreiungsbescheid, confirmation of exemption from statutory insurance — both issued by an insurer.

So the order runs the opposite way from the expected one: the insurer first, the university second. Until that paper exists, enrolment does not complete, however good your educational documents are.

On cost: students under 30 pay a reduced student rate of roughly €120–130 a month. Past 30, and from the 15th semester of study, the student rate no longer applies.

For a master's that matters: if you will be over thirty when the programme starts, budget the adult rate rather than the student one.

Japan: an obligation of residence, not of study

Japan's logic is different. Foreign residents staying three months or longer must join the National Health Insurance system (kokuho). It is a requirement of residency rather than of study, and the university has nothing to do with it.

You register at the municipal office where you live — the city or ward office. The premium in most cases is around ¥20,000 a year.

Cover is 70% of medical costs; the patient pays the remaining 30%. Anything outside the cover is paid in full.

What follows in practice

First: insurance belongs to the schedule, not to the document folder. In Germany it has to be arranged before matriculation; in Japan it means a trip to the municipal office in your first weeks.

Second: 70% cover is not 100%. Thirty per cent of serious treatment stays yours, and the first year's budget is the place to allow for it.

Third: age moves the price more than people expect. The gap between the student and the ordinary rate in Germany is several hundred euros a year — easier to plan for than to discover on arrival.

What to check for your own country

Ask three questions: whether local insurance is compulsory or a foreign policy is accepted, by when it has to be in place, and what share of costs it covers.

The second is the most underrated. It decides what your first fortnight looks like: settling in, or going from office to office because something else is waiting on the insurance.
