Can students not pay Japanese national health insurance premium in the first year?

If you make a long-term plan, you should abide by Japanese laws from the beginning and hand in everything that should be handed in in time. Because in the future, whether you apply for permanent residence or naturalization, you should start from entering Japan and check whether you have violated Japanese laws. And because this national health insurance premium is calculated according to your income and tax in the previous year, even if you receive it in the first year, it is very low. One year's national health insurance fee for international students is equivalent to one month's fee for Japanese. Moreover, after paying the insurance, the 30% paid by the school itself can be reported to 80%, which is cheaper than seeing a doctor in China. Without insurance, it is expensive to see a doctor, and some hospitals don't even treat people without insurance.
