What You Can Do at Once

📝 Task 📌 Notes
1. 出生届 (Birth Registration) Mandatory. Submit at the Resident Affairs section (戸籍課・市民課).
2. 出生届受理証明書 (Proof of Registration) Request immediately after submitting 出生届. Needed for insurance applications.
3. 子ども医療証申請 (Medical Subsidy Card) Apply right after registration—usually same counter or nearby.
4. 児童手当 (Child Allowance) Application Submit once the baby’s insurance card is issued—or ask how to reserve your spot. Some areas accept pre-submission.
5. 赤ちゃん訪問 (Home nurse visit request) Often asked about during this visit. Can be scheduled on the spot.

What to Bring

📄 Document / Item 📌 Who Provides / Where to Get It
出生届 form Given and partially filled by hospital
母子健康手帳（母子手帳） You already have this from pregnancy
保護者の本人確認書類 (ID, MyNumber) Residence card / MyNumber Card
印鑑（if required） Some cities still request a personal seal
通帳 or キャッシュカード（for 児童手当） Your bank info for allowance payment

Time-saving Tips

  • Ask the city hall counter if they offer “出生手続きまとめ窓口” (combined baby paperwork desk). Many cities do!

  • Some cities allow you to reserve an appointment online to avoid crowds.

  • If your baby’s insurance card isn’t ready yet, you can still start the 児童手当 paperwork and follow up later.
