National health insurance is compulsory for everyone in Japan. Those who have no income (low income) shall pay according to the minimum standard, and pay 10 every year, of which 9 periods are more than 700, and 1 period 1300 is more than 7800 in total.
As long as the insurance is handled, a thick bill of payment will be sent after the insurance certificate is sent (10). You can pay according to the payment cycle of each installment, or you can pay it in one lump sum.
These are all from the National Health Insurance Section of the Municipal Council (District Council).
