How do I apply for the system of direct payment of Childbirth and Childcare Lump-sum Grant to medical institutions in cases involving twins? How much are the benefits in such cases?

You do not need to apply to the Health Insurance Society. The benefits will be paid based on information from the medical institution.

The benefits will be paid to the medical institution in the amount of up to 500,000 yen/child or 1,000,000 yen for twins.
