Obstetrics and gynecology is defined by two simultaneous movements: structural contraction in obstetrics and expansion in gynecology and women's health. Though sharing one specialty designation, the two differ substantially in business model, location strategy, and revenue structure.
1. Macro environment — obstetric contraction is irreversible
Contraction in obstetrics is determined by the irreversible macro factor of declining births.
| Indicator | Earlier | Recent | Change |
|---|---|---|---|
| Births | 1,003,609 (2014) | 686,061 (2024) | −320,000 |
| Delivery facilities | 3,098 (2006) | 1,856 (2025) | −40% |
| — of which clinics | 1,818 | 951 | −48% |
| — of which general hospitals | 1,003 | 499 | −50% |
| Deliveries per physician | 120 (2015) | 81 (2025) | Declining |
Decline among clinics with beds handling deliveries is accelerating particularly. Beyond falling revenue from declining births, physician ageing, and succession challenges, "declining new openings is also a major factor." New openings of delivery-handling clinics with beds fell from a peak of 45 in 2014 to 8 in 2025.
Obstetric care carries structural burdens — round-the-clock coverage, on-call duty, high adverse event and litigation risk — obstructing both successor recruitment and new entry.
The dominant regulatory question: how childbirth costs are borne
Normal delivery has traditionally sat outside insured care as self-pay, offset by the childbirth lump-sum benefit (raised from ¥420,000 to ¥500,000 in April 2023). But costs rose after the increase, making cost inflation and regional disparity a policy problem.
Average normal delivery costs reached about ¥519,805 in FY2024 — above the ¥500,000 benefit — with Tokyo averaging over ¥640,000 against roughly ¥510,000 in regional areas.
The government is advancing legislation toward free childbirth costs, submitting amendments to the Health Insurance Act and Maternal and Child Health Act to the 2026 ordinary Diet session, aiming to set nationally uniform pricing. Insurance coverage of normal delivery itself remains contested, with concerns that it would further erode regional obstetric capacity.
Free and standardized care is expected to center on "standard delivery" and "standard prenatal checkups" (roughly 14 visits), with add-on services such as private rooms, special meals, and additional ultrasound remaining self-pay. Implementation is anticipated from FY2027 onward, and as of July 2026 the design remains fluid.
Meanwhile gynecology and women's health show a clear growth trend. The femtech and femcare market is estimated in the tens of billions of yen, expanding across menopause, menstruation, and fertility. METI published guidance on femtech adoption for companies and municipalities in May 2026.
2. Characteristics of newly opened clinics — the tilt away from delivery
New openings show a pronounced tilt toward gynecology clinics that do not handle deliveries. Practice models divide clearly between obstetric practices handling delivery and gynecology practices that do not, with the latter becoming mainstream in urban, station-adjacent locations serving a wide age range.
Obstetrics and gynecology accounts for a small share of all clinics (about 2,784 facilities, roughly 2.7%), making gynecology-focused practice an area with limited competition and room to enter.
The choice not to handle deliveries follows from economics. Obstetric practices face heavy constraints — large floor area, parking, physician residence near the clinic for on-call coverage — with correspondingly large initial investment. Opening capital runs roughly ¥50–130 million, with delivery-handling practices with beds requiring more. Gynecology practices, by contrast, operate without beds on outpatient care alone with no on-call burden, aligning with the practice ambitions of younger and women physicians who prioritize work-life balance.
Three success factors recur:
- Space design and privacy protection that reassures women (soundproofing, separated flows and entrances, waiting area consideration)
- Digital and social marketing reaching younger women
- Accessibility design including weekday evenings and weekends
Obstetrics and gynecology is a specialty where difficulty accessing care and difficulty raising concerns form psychological barriers, so clarifying positioning and building online communication capability are early acquisition steps.
Note also that obstetrics and gynecology is cited as having a high proportion of loss-making practices, driven by heavy fixed costs in delivery handling, patient volume variability, and the difficulty of managing accounting and unit pricing across mixed self-pay and insured care.
3. Revenue areas specific to obstetrics and gynecology
Fertility treatment
Since insurance coverage expanded in April 2022, this has remained among the most important topics. Coverage of IVF and ICSI (30% coinsurance, with age and cycle limits) substantially improved patient access, while advanced medical care not covered within insurance remains concurrent self-pay — establishing an operating pattern of optimizing cost through insurance plus advanced care plus municipal subsidy.
Municipal subsidies expanded further in FY2026: Tokyo began subsidizing up to ¥150,000 against insured coinsurance from April 2026, so municipal top-ups continue shaping patient burden even after coverage. Fertility clinics have strong patient draw, and facility requirements, track record, and visible outcomes (pregnancy rates) have become the competitive axis.
Perinatal care and epidural delivery
Amid contraction in delivery handling itself, this is one of the few growth areas. Demand for epidural delivery is expanding as an option for easier childbirth, and public subsidies have begun in the context of birth rate policy. Tokyo began subsidizing epidural delivery costs (up to ¥100,000) from FY2025.
Epidural delivery presupposes anesthesiology-grade staffing and safety management (personnel allocation, emergency response), making it a differentiating, unit-price-raising revenue source for capable facilities while carrying heavy setup costs and safety responsibility. It may grow in importance as the area where self-pay creates differentiation once standard delivery becomes publicly funded and standardized.
Gynecologic oncology screening and prevention
A stable acquisition base for gynecology practices. Regular cervical cancer screening participation remains low — one 2025 private survey found roughly 35% regular participation among women in their 20s to 50s, with HPV testing experience below 20% — leaving substantial room to improve participation.
For HPV vaccination, catch-up transitional measures ended at municipalities as of the end of March 2026, raising the importance of screening and awareness for cohorts that missed the opportunity. Screening, vaccination, and workup readily create continuing visit pathways, making prevention a solid revenue source across both insured and self-pay care.
Adolescent and menopausal care (life-stage medicine)
Attention is rising in step with the femtech current. Management of menopausal symptoms (hormone replacement therapy, kampo, lifestyle guidance) and of dysmenorrhea and PMS readily produces continuing visits, and corporate and municipal interest is high as a working women's health issue.
Sustaining relationships with patients across life stages — from adolescence through menopause and later life — is the core of maintaining a patient base under declining birth rates.
4. Self-pay services
Self-pay is gaining strategic importance as a revenue pillar insulated from fee revisions and declining delivery volumes, particularly in gynecology practices.
Fertility-related self-pay covers what sits outside insurance: advanced medical care, egg freezing, and AMH testing for ovarian reserve. Broadening the fertility patient base through coverage has, if anything, increased demand for adjacent self-pay testing and counseling.
Bridal checks are self-pay comprehensive examinations for women (and couples) before marriage and pregnancy, combining infectious disease, hormone, uterine and ovarian, and rubella antibody testing. Beyond the one-time examination, they function as a pathway into fertility care, contraception, and regular screening.
Contraceptives and emergency contraception are the self-pay area most compatible with online consultation. Ongoing low-dose pill prescription completes readily at a distance, lowering visit burden while generating stable recurring revenue. This area also faces price and convenience competition from online-only and online-primary players.
Aesthetic gynecology and femcare — vaginal and intimate area care, management of menopausal discomfort, laser procedures — center on quality of life. Gynecological medical expertise enables differentiation, letting practices emphasize the reassurance of a medical institution against aesthetic clinic competition.
Self-pay carries high value and margin with large business impact, but requires (1) attention to medical advertising guidelines, (2) clear separation from insured care and avoidance of mixed billing, and (3) transparent pricing with proper explanation and consent. In perinatal care especially, as free and standardized services advance, separating standard (publicly funded and insured) from optional (self-pay) services and standardizing accounting flows matters for both avoiding disputes and securing revenue.
5. Management implications
First, moving away from obstetric dependence toward gynecology and women's health is the structural direction. Models built on delivery revenue will consolidate into a subset of well-resourced facilities. New openings and succession planning should default to bed-free, outpatient-focused gynecology practice, and where delivery is retained, invest clearly in reasons to be chosen — epidural delivery, comfort — and in safety capability.
Second, the ability to design uninsured revenue separates strong operators. Systematically combining contraception (especially ongoing online prescription), bridal checks, fertility-related self-pay, and aesthetic gynecology and femcare on top of an insured foundation builds a revenue structure resilient to fee revisions and delivery volume swings.
Third, monitoring regulatory change and standardizing accounting operations is the near-term operational task. When free childbirth takes effect, separating standard from optional services, avoiding mixed billing, and organizing patient explanation and consent will be tested on the front line. Organizing accounting flows and pricing structures before the rules settle prevents confusion during transition and avoids lost opportunity.
Fourth, building relationships through prevention, screening, and life-stage continuity is the key to maintaining a patient base under declining births. Low cervical screening participation and the end of HPV vaccination catch-up show that room and social value in screening and awareness remain substantial.
6. How an AI EMR addresses these problems — feature by feature
Accounting in obstetrics and gynecology mixes publicly funded prenatal checkups, self-pay normal delivery, insured abnormal delivery, and add-on services within the same patient. Once free childbirth takes effect, that boundary gets redrawn again. Here is how Pottech's AI Karte supports it, feature by feature.
Feature 1: Billing and claims — keep three-layer accounting from breaking down
An automated calculation engine checks bundling conflicts, exclusions, and frequency limits, and determines eligibility automatically.
Accounting here mixes self-pay, public funding, and insurance within the same patient: prenatal checkups (public vouchers), normal delivery (self-pay), cesarean and other abnormal delivery (insured), private rooms and special meals (self-pay add-ons), fertility treatment (insured plus concurrent advanced care self-pay plus municipal subsidy).
If free childbirth with nationally uniform pricing takes effect, the boundary between standard delivery and prenatal care and add-on services will be redrawn. Without organized accounting flows through that transition, risk arises on both mixed billing avoidance and patient explanation. A system that proposes the self-pay/insured/public classification and required documents from the clinical content reduces the risk of accounting breaking down.
Feature 2: Patient PHR app integration ("Pote-kun") — support life-stage continuity
Appointment booking, medication reminders, pre-visit web questionnaires, fee notifications, and LINE login with push notifications.
The strategic core here is accompanying patients across life stages from adolescence through menopause and later life. But touchpoints vary entirely in interval and content by period: dysmenorrhea visits, fertility care, pregnancy and delivery, postpartum, screening, menopause.
Ongoing low-dose pill prescription competes directly with online-only players, and patients leave if convenience lags. Recall for cervical cancer screening is a direct lever on the current 35% participation rate. Whether one-time touchpoints become continuing relationships determines the patient base under declining births.
Feature 3: Integrations and APIs — bring menstrual tracking app data into care
An OAuth2 gateway, MCP server, HAPI FHIR, and the LINE Messaging API.
Menstrual tracking and PHR apps are a core femtech category, and more patients bring app-recorded cycle and symptom data into consultations. Ingesting that into the EMR makes it usable in decisions about ongoing LEP and HRT prescription and functions as pre-visit information gathering.
For integration with online consultation (ongoing contraceptive and emergency contraception prescription, fertility and menopause follow-up), connecting booking, questionnaires, prescription, payment, and charting end to end substantially affects the efficiency of recurring revenue.
Feature 4: Document generation — standardize consent and self-pay pricing disclosure
AI generates medical documents from patient data, with registered templates preserving the clinic's format.
Self-pay menus require transparent pricing and proper explanation and consent. Bridal check package contents, epidural delivery risk explanation, the cost structure of concurrent advanced care in fertility treatment — all involve many items to explain, presupposing written presentation.
After free childbirth takes effect, clinics must clearly distinguish for patients what is included in standard delivery from what is a self-pay option. Generating explanation documents, consent forms, and price lists from one source prevents the most common failure: inconsistency between them.
Feature 5: Booking and reception — encode privacy consideration
In-person and online bookings are managed together with segmented slot management.
This specialty carries psychological barriers around access and raising concerns. Having prenatal checkup patients, fertility patients, and young dysmenorrhea patients in the same waiting room can itself become a barrier.
Separating waiting areas through time-slot booking and avoiding phone explanations through online booking are direct acquisition measures in a specialty competing on patient experience. Managing long procedures such as epidural delivery and fertility care alongside short encounters such as contraceptive prescription on one calendar is also necessary.
Feature 6: Charting and orders — support consultations with long explanation time
AI generates SOAP notes from consultation audio, and questionnaires are digitized automatically.
Fertility treatment explanation, epidural delivery consent, menopausal lifestyle guidance. This specialty involves long physician explanation time and heavy documentation. Fertility care in particular requires time explaining treatment approach, success rates, and cost, and the dialogue supporting patient decision-making determines care quality. Automating documentation is the means to redirect time toward that dialogue.
Feature 7: Practice analytics — measure the impact of regulatory change
Visit volume, revenue per patient, monthly trends, and patient attributes are aggregated and visualized automatically.
Facing a regulatory change that directly alters the revenue structure, tracking its impact numerically is the precondition for management decisions. How did delivery unit value change? How is self-pay option uptake trending? How is the revenue split between gynecology outpatients and obstetrics moving?
Only with these visible can you make the fundamental judgment: how far to maintain obstetrics, and how far to shift toward gynecology and self-pay.
