International students can also use the student payment special system for national pension insurance premiums.

Even if you are a foreigner, if you are 20 years old or older, you must join the National Pension Plan and pay insurance premiums.
However, international students are only allowed to work up to 28 hours a week, so many people may not be able to afford to pay the premiums for the National Pension.
In such a case, simply not paying premiums is not recommended because it means that you are not fulfilling your obligation to participate in the National Pension.
In such cases, foreign students can also use the Special Payment System for National Pension Premiums for Students.
This means that if the student's annual income is below a certain amount, the payment of the National Health Insurance premium can be deferred by applying.
If you use this system, you will be fulfilling your obligation to participate in the national pension, but you will be deferred from paying insurance premiums.
However, in order to use this system, it is necessary to go to a school that is eligible for special payment for students of the National Pension Insurance.
