What happens if total delivery costs are under 500,000 JPY?

If your hospital invoice is below 500,000 JPY, you can apply to your health insurer to have the surplus difference refunded directly to your bank account.

How does the grant apply to multiple births like twins?

The grant is legally tied per child born: twins qualify for 1,000,000 JPY and triplets qualify for 1,500,000 JPY.

The health insurance fund disburses the 500,000 JPY directly to your hospital, meaning parents only pay the remaining out-of-pocket balance at discharge.
