Children Born in Japan to Irish-born Parents

If you are born in Ireland, your child automatically receives Irish citizenship and does not have to be registered on the Foreign Births Register.

You can apply for a passport directly (without having to apply for citizenship, thereby saving 20,000 JPY).
