Money you're owed in Koto.
Three child benefits, all paid by the ward or by Tokyo, none of them automatic. Enter your children's birthdays to see what you should be getting.
Foreign residents are eligible — what matters is a 住民票 in the ward, not nationality. None of these three has an income limit.
Your children's dates of birth
Include older children up to 22 if you still support them — they don't get paid, but they change the birth order, and the third child onward is worth ¥30,000 a month.
