Free Childbirth in Japan: When It Starts and What Is Covered

In short: the current ¥500,000 lump sum versus the new system, split into what is decided, under review, and reported only

Based on the text of the amending act (supplementary provisions article 1(6), 14 and 15; Health Insurance Act new articles 98-2 to 98-24, 101 and 112-2) and document 2 of the 218th Medical Insurance Subcommittee. Current rules from[Japan Health Insurance Association, childbirth lump sum (in Japanese)].

What childbirth costs: an average of ¥520,000, ¥648,000 in Tokyo and ¥404,000 in Kumamoto, with over half above ¥500,000

MHLW figures put the average cost of a birth without insured treatment (excluding private-room charges and the obstetric compensation premium) at ¥520,000 in fiscal 2024, up from ¥507,000 in fiscal 2023. By prefecture, Tokyo is highest at ¥648,309 and Kumamoto lowest at ¥404,411. Including room charges, mothers' total payments were ¥754,243 in Tokyo and ¥460,634 in Kumamoto[MHLW, review panel 1st meeting, document 2 (PDF, in Japanese)].

Japan Health Insurance Association data for fiscal 2025 (which includes the compensation premium) show an average of ¥528,554 for births without insured treatment, and adding up the bands, more than 60% cost ¥500,000 or more[same panel, document 3 (PDF, in Japanese)]. That the ¥500,000 lump sum no longer covers most births is the background to the reform. Costs by facility can be checked on Birth Navi.

What becomes free and what does not: the base rate is free, private rooms stay out of pocket, caesareans remain insured treatment

The subcommittee's diagram divides the mother's costs into three layers.

• Delivery care (normal birth): the state sets a nationwide base rate, adds supplements reflecting each facility's staffing and role, and insurers pay the facility directly. No cost to the mother.
• Insured treatment (caesarean and other abnormal deliveries): unchanged, with the usual 30% co-payment and the high-cost medical expense cap. To ease that co-payment, a separate flat cash payment to every mother (the childbirth lump sum) is provided.
• Amenities: private rooms, upgraded meals and the like stay out of pocket. Facilities must explain them in advance and report to the state for full disclosure.

Epidural (painless) delivery appears in the Diet's supplementary resolutions only as a call to secure safe provision; whether it is included in the base rate is not stated in the documents. It is a point for the December plan.

The level of the base rate and the cash payment, and the effect on premium finances, will be decided after the "review panel on the content of care in pregnancy, childbirth and the postpartum period" (started 1 October, meeting once or twice a month, with a survey of 2,139 facilities and about 2,000 recent mothers) completes its work[MHLW, review panel (in Japanese)].

What happens to the lump sum: renamed the "childbirth lump sum", the balance after the delivery benefit goes to the facility and any surplus to the mother

The childbirth and childcare lump sum is not abolished; it becomes the "childbirth lump sum" with a new name and role (amended article 101). The amount is set by cabinet order. Insurers pay the facility the remaining cost after the delivery benefit, and if the lump sum is larger, the difference is paid to the mother. At a facility whose charges fit within the base rate, the whole lump sum stays with the family.

Watch the transition rule. Even after the new system starts, facilities that notify the minister may keep settling under the current lump sum "for the time being" (special delivery facilities, supplementary article 15). The House of Councillors' resolution urges that "as many delivery facilities as possible be encouraged to choose the new benefit structure", but a period in which the system differs by facility is possible. Which one applies at your facility will be shown in its advance explanation and on Birth Navi.

Who is affected: births before the start date stay on the current system, and births within six months of leaving a job are covered

• Births before the start date: settled with the current ¥500,000 lump sum (supplementary article 14). If the reported second-half-of-fiscal-2027 start holds, births up to the first half of 2027 are under the current system.
• Births on or after the start date: delivery benefit plus childbirth lump sum at new-system facilities; the current lump sum at special delivery facilities.
• Births after leaving a job: with one year or more of continuous membership up to the day before leaving, births within six months are covered by the former insurer (new article 98-24), as now.
• National health insurance members: the same delivery benefit under article 54-5 of the National Health Insurance Act, with the amount following the Health Insurance Act.

There is no need to time a birth around the reform. The difference matters for people giving birth at facilities charging well over ¥500,000, where the new system should reduce out-of-pocket costs. Amounts are not yet set; this article will be updated when the December plan appears.

Tax and other benefits: the medical expense deduction shrinks as out-of-pocket costs fall, while the ¥100,000 pregnancy support benefit is separate

Childbirth costs qualify for the medical expense deduction, but the lump sum is subtracted as compensation (maternity allowance is not)[NTA, No. 1124 childbirth costs eligible for the medical expense deduction (in Japanese)]. If the new system cuts what you pay, the deductible amount falls accordingly. Check-up and travel costs once pregnancy is confirmed, taxi fares to hospital for the birth and hospital meals remain deductible.

The Children and Families Agency's pregnancy support benefit (¥50,000 plus ¥50,000 per child) is separate and continues. Maternity allowance, childcare leave benefits and the premium exemption are covered in money you receive for childbirth and childcare and how much maternity allowance is and when it is paid.

Summary

• Free childbirth was decided by the amended Health Insurance Act (passed May 2026, promulgated 5 June). It starts "within two years of promulgation", so by 4 June 2028; the press reports the second half of fiscal 2027
• The mechanism is a "delivery benefit" at a nationwide base rate paid directly to facilities, plus a flat "childbirth lump sum" to every mother. Amounts are settled around December and referred to the medical council
• Within the base rate there is no charge. Amenities such as private rooms stay out of pocket with disclosure; caesareans remain insured treatment. Epidurals are undecided
• Average childbirth cost was ¥520,000 in fiscal 2024 (Tokyo ¥648,000, Kumamoto ¥404,000), and over 60% of births exceed the ¥500,000 lump sum
• Facilities that opt out keep the current lump sum for the time being; births before the start date stay on the current system; births within six months of leaving a job are covered
