Pregnancy & Birth in Japan: A Step-by-Step Guide
Just found out you're expecting in Japan — and not sure what happens next? The Japanese maternity system is well organized and largely subsidized, but it can feel opaque if you don't read Japanese. This guide walks you through every stage, from a positive test to registering your baby's birth, so you always know what the next step is. Note: rules, costs and benefits vary by municipality and change over time, so treat figures as approximate and always confirm with your city or ward office and official sources.
Contents
1. Confirming your pregnancy
The journey usually begins with a home pregnancy test (available at any drugstore, called 妊娠検査薬 / ninshin kensa-yaku). A positive result is not a medical diagnosis on its own, so the next step is to visit an obstetrics & gynecology clinic (産婦人科 / sanfujinka) to confirm the pregnancy and estimate how far along you are.
This first visit is typically around 5–6 weeks, once a heartbeat can be detected. The doctor confirms the pregnancy with an ultrasound, calculates your estimated due date (出産予定日), and gives you a certificate or note of pregnancy — this is what you take to the city or ward office in the next step.
Good to know: This very first confirmation visit is usually not covered by national health insurance and is paid out of pocket (often several thousand yen). Routine prenatal checkups are also not "insurance covered" in the usual sense — instead they are supported by subsidy tickets you receive after registering (see Section 3).
It's also a good moment to start thinking about lifestyle basics that doctors commonly advise during pregnancy — eating a balanced diet, being cautious with alcohol and smoking, and asking your clinic before taking any medication or supplements. If you were already taking prescription medicine before pregnancy, mention it at this first visit so your doctor can advise you. These are general points; your own care plan should always come from your doctor or midwife.
2. Registering your pregnancy & getting the Maternity Handbook
Once your pregnancy is confirmed, report it (妊娠届 / ninshin todoke) at your local city or ward office (市役所・区役所 / shiyakusho / kuyakusho). In return you receive the Maternity Handbook, called the 母子健康手帳 (Boshi Kenkou Techou, often shortened to 母子手帳 / Boshi Techo).
What is the Boshi Techo?
It's a single booklet that records your pregnancy and your child's health from before birth through early childhood — checkup results, measurements, vaccinations and growth. You bring it to every prenatal visit and, after birth, to your baby's checkups. Keep it safe; it's the official health record for both of you.
What you get with it
- The handbook itself (many municipalities offer foreign-language versions — English, Chinese, Portuguese, Vietnamese and more; ask at the counter).
- A set of prenatal checkup subsidy tickets (受診票 / jushinhyou) that reduce the cost of regular checkups.
- Information on local maternity classes, benefits, and a Maternal & Child Health Notification.
Bring your residence card or My Number, and your pregnancy certificate. Many offices also offer a short interview with a public health nurse to connect you with local support — useful if you have questions about the system in your situation.
3. Prenatal checkups & subsidy tickets
Regular prenatal checkups (妊婦健診 / ninpu kenshin) are the backbone of maternity care in Japan. A typical schedule is around 14 visits across the pregnancy:
- Up to ~23 weeks: about every 4 weeks
- 24–35 weeks: about every 2 weeks
- 36 weeks to birth: about every week
Each visit may include weight and blood-pressure checks, urine tests, measuring your bump, listening to the baby's heartbeat, and periodic ultrasounds and blood tests. The subsidy tickets from your handbook cover much of the standard cost, though you may still pay some out of pocket depending on your municipality and any extra tests.
Tip: Keep your handbook and remaining tickets together in your bag. If you move to a different municipality during pregnancy, ask the new office about exchanging your tickets — coverage is set locally.
For a deeper dive into the handbook and what happens at each checkup, see our dedicated article: The Maternity Handbook & Prenatal Checkups in Japan.
4. Choosing where to give birth
In Japan you generally choose your birth facility yourself and book a delivery slot early (分娩予約 / bunben yoyaku) — sometimes within the first trimester, because popular places fill up. There are three main types:
Hospital (病院 / byouin)
University or general hospitals have the most resources, including NICUs and specialists. A good choice for higher-risk pregnancies, multiples, or if you want medical options on hand.
Clinic (クリニック・診療所)
Smaller maternity clinics are the most common choice for low-risk births. They tend to be more personal and often have nice amenities. If a complication arises, they transfer to a partner hospital.
Midwifery house (助産院 / josan-in)
Birth centers led by midwives, oriented toward natural, low-intervention birth. They handle low-risk pregnancies and work with a backup hospital. Note that they generally cannot provide epidurals or surgical delivery on site.
Think about language support, distance from home, the kind of birth you want, and cost. If English support matters to you, read Finding an English-Speaking Maternity Hospital in Japan before you book.
Book early. One thing that surprises many newcomers is that you often need to reserve your delivery slot (分娩予約) early in pregnancy — sometimes in the first trimester — because popular and English-friendly facilities fill up fast. Ask about booking at your very first confirmation visit, and have a backup choice in mind.
5. The birth, costs & the lump-sum allowance
When labor begins, you head to your booked facility. Average hospital stays in Japan are longer than in many countries — often about 5–6 days for a vaginal birth and longer for a cesarean — with support for recovery and learning to feed and care for your baby before you go home.
How much does it cost?
A normal, uncomplicated birth is not treated as a medical illness, so it isn't covered by ordinary health insurance — you pay the facility's fee. Costs vary widely by region and facility. To offset this, Japan provides the lump-sum birth allowance (出産育児一時金 / shussan ikuji ichijikin) through your health insurance.
The direct-payment system
Most people use the direct-payment system (直接支払制度 / chokusetsu shiharai seido): your insurer pays the allowance directly to the hospital, so you only settle the difference at checkout instead of paying everything upfront. If the allowance exceeds your bill, you can claim the remainder back.
To use the direct-payment system, you typically sign an agreement with your facility ahead of the birth — usually arranged during your pregnancy, not at the last minute — so it's something to confirm with your hospital well in advance. If your facility doesn't offer it, there's also a "receipt-based payment" route where you pay first and claim the allowance back from your insurer afterward. Either way, the allowance is processed through your health insurance, whether that's your employer's plan, National Health Insurance, or a family member's coverage. If you're not sure which applies to you, your city or ward office can point you in the right direction.
Please confirm the current amount. The lump-sum allowance figure is set nationally and can change, and your final out-of-pocket cost depends on your facility and region. Check the latest amount and procedure with your health insurer and the hospital well before your due date. See also: Childbirth Costs & the Lump-Sum Allowance. A C-section, being a medical procedure, may be partly covered by health insurance and high-cost medical care support — ask your insurer.
6. After birth: registering & support
Register the birth within 14 days
You must submit a birth notification (出生届 / shusshou todoke) at the city or ward office within 14 days of the birth. The hospital provides a birth certificate section completed by the doctor or midwife, which forms part of the form. Bring your handbook and personal documents.
If you or your partner are not Japanese nationals, there are extra steps to keep in mind, such as notifying your embassy, applying for the baby's passport, and arranging the baby's residence status — check with both your ward office and your embassy promptly, as some have their own deadlines.
Health insurance & child allowances
Soon after registering the birth, enroll your baby in health insurance and apply for available family benefits at the same office. Japan offers a regular child allowance (児童手当) and free or low-cost medical care for infants, with details and amounts set locally.
Health checks for you and your baby
You'll typically have a one-month postpartum checkup for yourself and your newborn, followed by a schedule of infant health checkups and vaccinations recorded in the handbook. For what to expect, see Infant Health Checkups & Vaccinations.
Don't overlook your own recovery
It's easy to focus entirely on the baby, but the weeks after birth (often called the postpartum or "fourth trimester" period) are demanding physically and emotionally. Japan has a tradition of rest after birth, and many areas offer postpartum care services, home visits by public health nurses or midwives, and support for new parents. If you feel persistently low, anxious or overwhelmed, that's worth raising — these feelings are common, and help is available. Reach out to your clinic, your municipality, or trusted people around you rather than carrying it alone.
A note on medical questions: This guide is general information about the system, not medical advice. For anything about your own health or your baby's, talk to your doctor or midwife — and don't hesitate to use your municipality's public health nurses, who can support new parents.

日本での妊娠・出産の流れ|完全ステップガイド
日本で妊娠がわかったけれど、次に何をすればいいか分からない——。日本の出産制度は整っていて補助も手厚い一方で、日本語が読めないと分かりにくく感じることがあります。本記事では陽性反応から出生届まで、全ステップを順を追って解説します。※制度・費用・給付は自治体や時期によって異なり変更されることがあります。金額は目安とし、必ずお住まいの市区町村役所や公式情報でご確認ください。
1. 妊娠の確認
多くの場合、市販の妊娠検査薬から始まります(ドラッグストアで購入可)。陽性は医学的な確定ではないため、次に産婦人科を受診して妊娠の確認と週数の確認を行います。
初診はおおむね妊娠5〜6週ごろ、心拍が確認できる時期が目安です。超音波で妊娠を確認し、出産予定日を算出。妊娠の証明(医師の記載・書類)を受け取り、次のステップで市区町村役所へ持参します。
知っておきたいこと:この初診は通常、健康保険の適用外で自費(数千円程度のことが多い)です。定期的な妊婦健診も一般的な「保険適用」ではなく、妊娠届の後に受け取る補助券で支援されます(第3章)。
この時期は、妊娠中に医師がよく勧める生活の基本——バランスの良い食事、飲酒・喫煙への注意、薬やサプリは服用前にクリニックへ相談すること——を意識し始める良いタイミングでもあります。妊娠前から処方薬を飲んでいる場合は、初診で必ず伝えましょう。これらは一般的な目安です。ご自身のケア方針は必ず医師・助産師から受けてください。
2. 妊娠届と母子健康手帳の受け取り
妊娠が確認できたら、お住まいの市区町村役所で妊娠届を提出します。すると母子健康手帳(母子手帳)が交付されます。
母子手帳とは?
妊娠中から子どもの乳幼児期までの健康を記録する一冊です。健診結果・計測・予防接種・成長などを記録し、妊婦健診や出産後の乳児健診に毎回持参します。母子双方の公式な健康記録なので、大切に保管しましょう。
一緒に受け取れるもの
- 母子手帳本体(多くの自治体で外国語版を用意——英語・中国語・ポルトガル語・ベトナム語など。窓口で確認を)。
- 妊婦健診の補助券(受診票)一式。定期健診の費用負担を軽くします。
- 母親学級・各種給付などの案内。
在留カードやマイナンバー、妊娠の証明書を持参しましょう。多くの役所では保健師との面談も用意され、地域のサポートにつないでくれます。
3. 妊婦健診と補助券
妊婦健診は日本の妊娠管理の基本です。一般的なスケジュールは妊娠期間を通じて約14回です。
- 〜23週ごろ:約4週間に1回
- 24〜35週:約2週間に1回
- 36週〜出産:約1週間に1回
各回で体重・血圧、尿検査、腹囲・子宮底長の計測、赤ちゃんの心音確認、定期的な超音波や血液検査などを行います。母子手帳の補助券で標準的な費用の多くがカバーされますが、自治体や追加検査によっては自己負担が残ることもあります。
ポイント:母子手帳と残りの補助券は一緒に持ち歩きましょう。妊娠中に別の自治体へ転居した場合は、新しい役所で補助券の交換について確認を。補助は自治体ごとに設定されています。
手帳と各健診の詳細は専用記事もご覧ください:母子健康手帳と妊婦健診。
4. 産む場所を選ぶ
日本では基本的に自分で産院を選び、早めに分娩予約をします(人気の施設はすぐ埋まるため、初期に予約することも)。主に3タイプあります。
病院
大学病院や総合病院は設備が最も充実し、NICUや専門医もあります。ハイリスク妊娠・多胎、医療的な選択肢を手元に置きたい方に。
クリニック・診療所
小規模な産科クリニックはローリスク出産で最も一般的。きめ細やかで設備が快適なことも多く、合併症時は提携病院へ搬送します。
助産院
助産師が中心の施設で、自然分娩・低介入の出産志向。ローリスク妊娠を扱い、バックアップ病院と連携します。原則として無痛分娩や手術分娩は行えません。
言語サポート、自宅からの距離、希望する出産スタイル、費用を考えて選びましょう。英語対応を重視するなら、予約前に英語対応の産院の探し方もご覧ください。
予約は早めに。初めての方が驚く点として、日本では妊娠初期(ときに妊娠初期のうち)に分娩予約が必要なことが多く、人気の施設や英語対応の施設はすぐ埋まります。初診の段階で予約について尋ね、バックアップの候補も考えておきましょう。
5. 出産・費用・出産育児一時金
陣痛が始まったら予約した施設へ。日本の入院期間は他国より長めで、経腟分娩で5〜6日程度、帝王切開ではさらに長いことが多く、回復と授乳・育児を学ぶサポートを受けてから退院します。
費用はどのくらい?
正常分娩は病気としての扱いではないため、通常の健康保険は適用されず、施設の費用を支払います。費用は地域・施設で大きく異なります。これを補うため、日本では健康保険から出産育児一時金が支給されます。
直接支払制度
多くの方は直接支払制度を利用します。保険者が一時金を病院へ直接支払うため、退院時は差額のみの精算で済みます。一時金が請求額を上回れば、差額を後日受け取れます。
直接支払制度を使うには、通常は出産前に施設と合意書を取り交わします(直前ではなく妊娠中に手続きすることが多い)ので、早めに病院へ確認しておきましょう。施設が対応していない場合は、いったん自分で支払い、後から保険者へ一時金を請求する「受取代理/償還払い」の方法もあります。いずれにせよ一時金は健康保険を通じて処理されます(勤務先の保険・国民健康保険・家族の扶養など)。自分がどれに該当するか分からない場合は、市区町村役所で案内してもらえます。
金額は最新の情報をご確認ください。一時金の額は国が定めており変更されることがあります。最終的な自己負担は施設や地域によって異なります。出産予定日の前に、健康保険の保険者と病院で最新の金額・手続きをご確認ください。あわせて:出産費用と出産育児一時金。帝王切開は医療行為のため、健康保険や高額療養費の対象になることがあります(保険者に確認を)。
6. 出産後:手続きとサポート
出生届は14日以内に
出産後14日以内に、市区町村役所へ出生届を提出します。病院が医師・助産師の記載する出生証明の欄を用意し、これが届出の一部になります。母子手帳と本人確認書類を持参しましょう。
ご自身やパートナーが外国籍の場合は、大使館への届出、赤ちゃんのパスポート申請、在留資格の手続きなど追加の手続きがあります。締切が独自に設けられている場合もあるため、役所と大使館の両方に早めに確認を。
健康保険と各種手当
出生届の後すぐに、同じ役所で赤ちゃんを健康保険に加入させ、利用できる手当を申請します。日本には児童手当があり、乳幼児の医療費が無料または低額になる制度もあります(内容・金額は自治体ごと)。
ママと赤ちゃんの健診
通常、産後1か月健診をママと新生児が受け、その後は乳児健診と予防接種のスケジュールが母子手帳に記録されます。詳しくは乳児健診と予防接種をご覧ください。
ご自身の回復も大切に
つい赤ちゃんに意識が向きがちですが、産後の数週間は心身ともに負担が大きい時期です。日本には産後に休む文化があり、地域によっては産後ケアサービス、保健師・助産師の家庭訪問、新米パパ・ママ向けの支援が用意されています。気分の落ち込みや不安、いっぱいいっぱいの状態が続くなら、ためらわず相談を。こうした気持ちはよくあることで、支えは必ずあります。一人で抱え込まず、クリニックや自治体、信頼できる周囲の人に頼りましょう。
医療的な相談について:本記事は制度の一般的な情報であり、医療上の助言ではありません。ご自身や赤ちゃんの健康に関することは医師・助産師に相談を。自治体の保健師も新米パパ・ママを支えてくれます。
