In a rich city, doctor's bill for kids is 0 yen ($0.00 €0.00)
In rich cities, there is no charge for medical treatment for kids (under 12 or under 15).
It means I do not have to pay doctor expense of my children to a hospital. Instead of me, city official pays that cost. Usually we pay 30% of medical cost by ourselves and the government insurance covers remaining 70%. Rich cities cover this 30% cost in stead of us. Unfortunately poor cities can not do this.
These are tablets of medicine for kids.
If you want to know something, ask me please.
