The medical insurance you mentioned is the national health insurance. Anyone with a legal visa (such as studying abroad, finding employment, working) can go to the local service office. Japan doesn't have a temporary residence permit, but only foreigners can get a visa (20 12). Students' medical insurance premiums can be reduced or exempted. It is estimated that 1 year is about 700 RMB (1 10,000 yen), and in principle, medical insurance premiums below 2 million RMB can be declared. However, some occasions cannot be fully reimbursed, such as some private hospitals and clinics, and bed fees and the like must be paid by themselves.

Just because you need to apply for a medical visa to see a dentist in Japan, because there is no welfare there, and the expenses include medical expenses and accommodation. If 1 week is estimated to be less than 50,000 RMB, it can be settled easily.

I once went to Japan from Germany to study for a master's degree 10. Now I'm back in China, running the manufacturing industry. The requirements for studying in Japan are still relatively high, and the procedures are very complicated. I don't want to talk about them in turn. Go to formal institutions first, such as Japanese embassies and consulates and some formal study abroad institutions.
