i The national health insurance system

Japan is recognised worldwide as a society of health and longevity at relatively low costs. Like most developed countries, it has universal health insurance, referred to as the national health insurance system (NHIS), which was established in 1961 (see Section II), but Japan also has a privately initiated medical care provision system. These two systems are sometimes called the 'publicly funded and privately delivered' system.

However, the sustainability of the NHIS has been questioned because of the rapid rise in healthcare costs because of Japan's low fertility rate, ageing population, growing use of expensive technologies and long-term primary budget deficit for nearly three decades.

To tackle those challenges, Japan adopted several reforms, including the following:

  1. The Medical Care Plan (see Section II) was adopted in 1985.
  2. The Medical Care System for the Elderly in the Latter Stage of Life, which is a social insurance system for those aged 65 and over who require long-term care and social services, was introduced in 2000. To maintain sustainability, this system is reviewed and revised every three years.
  3. The Integrated Community Care System, which is a comprehensive community-level system that integrates healthcare, nursing care, prevention, housing and livelihood support to enable the elderly to live self-sufficiently in environments that are familiar to them, was promoted as a matter of national policy from 2012.
  4. The Comprehensive Reform of Social Security and Tax was started in 2012. This reform consisted of joint reforms of the social security and taxation systems to improve the fiscal sustainability of Japan's social security system. This cross-system reform plan includes measures for the support of children and child-raising, the employment of young people, reforms of medical and long-term care services, pension reforms, measures against poverty and income inequality, and measures for low-income earners.
  5. The Regional Healthcare Vision (see Section II) was started in 2015.
  6. The Guidelines for the Appropriate Implementation of Online Medicine and the related question-and-answer (Q&A) documentation (see Section IX) were released by the Ministry of Health, Labour and Welfare (MHLW) in 2018.
  7. Measures for procuring physicians (see Section II), which started on 1 April 2019.

Moreover, Japan's privately initiated medical care provision system has been gradually shaped by a planned-economy approach to make the healthcare economy more efficient.

ii Significant issues to be tackled with assistance from professionals

The following are some of the significant issues that will eventually require the support of financiers, lawyers, accountants and other professionals.

Uneven distribution of physicians

The phenomenon of karoshi (death caused by overwork or job-related exhaustion) is a reality in Japan, even in the medical industry. In 2017, the karoshi of medical interns in 2015 and 2016 in severe working environments were determined as workers' accidents. Although it is anticipated2 that the supply and demand of physicians will balance out around 2028 (on the premise of 60 working hours a week and other conditions) or 2033 (on the premise of 55 hours a week and other conditions), the uneven distribution of physicians, in both geography and practice areas, and their severe working environment remain a major problem (see Sections II and IX).

Ageing and deterioration of medical institutions

The number of medical facilities rapidly increased from the late 1970s to the early 1980s in anticipation of the introduction of restrictions on the number of hospital beds in 1985. The statutory depreciation period for steel-reinforced concrete buildings of 39 years, which applies to these facilities, is now expiring. In addition, many of these facilities do not satisfy the latest earthquake-resistance standards. Therefore, a considerable number of medical facilities will need large-scale repairs, if not complete reconstruction (see Section IX).

Family-oriented governance of medical corporations

Medical corporations are corporate bodies that are operated by administrative bodies for medical care service programmes, and that retain the non-profit status required for medical practice in Japan.

Under the seventh major revision of the Medical Care Act (the 7th Revision) promulgated in 2016, almost all of a certain scale or category of medical corporations were statutorily obliged from April 2019 to comply with the Japan GAAP for medical corporations, accept external audits, and publish written reports on transactions of a certain scale with their directors, close relatives of directors, or other specified persons. As a result, a review of corporate governance systems, especially in family-owned medical corporations, is anticipated (see Sections VI and IX).

New industrial technologies

Ultra-expensive pharmaceuticals, radiotherapy facilities, ICT, AI, robotic surgery, telemedicine, and other industrial technologies have evolved and will keep evolving. These technologies increase and deepen inter-relations between the medical industry, for-profit corporations, and organisations that confront the conventional philosophy on the non-profit status of medical practice in Japan (see Section IX).


i General

Although Japan residents avail themselves of private health insurance, Japan boasts a working NHIS for its residents. Under the NHIS, (1) residents in Japan are required to enrol in the public health insurance system, (2) there is freedom of choice of medical institutions, and (3) the medical services, medication and medical devices that are covered by NHIS are available at a low cost under a nationwide uniform price system.

ii The role of health insurance

As long as Japan legal residents pay the required insurance premiums, they are entitled to medical services covered by the NHIS. Depending on age and income, the insured co-pay 10 to 30 per cent of the service fees to the medical provider. While the NHIS coverage is wide and includes most basic medical services and conditions, there are medical services, such as heavy particle beam therapy or certain new experimental therapies, that are not covered. The NHIS does not allow NHIS-covered medical treatment to be provided alongside uncovered treatment, and disallows NHIS coverage of the entire NHIS-covered and uncovered medical treatments, except in very limited circumstances. Thus, many individuals opt to take out private health insurance for medical services not covered by the NHIS.

iii Funding and payment for specific services

The NHIS has allowed Japan to enjoy the world's highest level of life expectancy and healthcare standards, but because it allows patients to choose medical facilities and providers, an enormous amount of public subsidy is required to maintain universal health insurance coverage. Thus, its sustainability is heavily affected by tax revenues and other public funds.

To control the supply of and demand for medical resources, Japan adopted the Medical Care Plan in 1985, under which the MHLW obligates each prefectural government to make periodic reports on its prefecture-specific healthcare system. These reports must include an estimate of future supply and demand of hospital beds in the 'secondary medical service areas'3 and their medical functions (such as acute phase function and recovery phase function), basically targeting (1) cancer, cerebral apoplexy, cardiovascular diseases, diabetes and mental disorders, referred to as the 'five diseases'; (2) emergency medical care, medical care in the event of disasters, medical care in remote areas, perinatal medical care, and paediatric medical care (including paediatric emergency medical services), referred to as the 'five services'; and (3) home medical care. The reports used to be required every five years, but from 1 April 2018, the reports must be submitted once every six years with provisional revisions to be made every three years. If existing hospital beds with certain medical functions exceed the standard number of that type of hospital bed in the secondary medical service areas set out in the Medical Care Plan, the prefectural governor can directly or indirectly refuse applications for additional hospital beds.

From 2015, the MHLW further obligated each prefectural government to create, within its Medical Care Plan, a prefecture-specific vision called the Regional Healthcare Vision. This vision requires the use of a newly adopted reporting system (introduced in 2014) on medical functions of hospital beds to estimate healthcare supply and demand for 2025 (when the baby boomers will reach the age of 75) and establish region-specific healthcare systems by 2025. Furthermore, as of 2018, each prefectural governor can refuse applications for additional hospital beds if existing hospital beds with certain medical functions exceed the estimated number of that type of hospital bed in the Regional Healthcare Vision areas (which are areas similar to secondary medical service areas).

Medical service fees payable to medical institutions and pharmacies for covered medical services, medication and devices are determined every two years by the MHLW based on discussions within the Central Social Insurance Medical Council. The FY 2018 revision of medical fees covered by the NHIS applicable for two years from 1 April 2018 showed an average decrease of 1.19 per cent from the previous fees. That average decrease represents an increase in medical service fees but a decrease in the prices of drugs and supplies.


Unlike some countries where patients are required to first see a general practitioner even for insurance-covered medical services or have no direct access to high-functioning hospitals, Japan's free access policy allows patients to directly access high-functioning hospitals for medical services covered by the NHIS. To cope with increasing medical costs, however, public policy guides patients and physicians to seek a general practitioner first. For example, in the FY 2018 revised fees, medical fees were increased for medical institutions that strengthen their general practitioner practice. Generally, patients without a referral from a general practitioner have to pay ¥5,000 as a first consultation fee to visit hospitals with at least 400 beds (a number that legislators are considering lowering).


i Regulators

The MHLW regulates the licensing and overall practice of healthcare professionals, including physicians and dentists.

Licensed physicians and dentists, however, are not automatically registered with the NHIS and must register as insurance physicians or insurance dentists with the Local Bureau of Health and Welfare where they are located.

Prefectural governments are also responsible for overseeing the management and operation of medical institutions on a regional basis.

As can be seen in the adoption of the Medical Care Plan and the Regional Healthcare Vision, there is a tendency to shift administrative powers over medical practitioners and institutions from the national government to prefectural governments.

ii Institutional healthcare providers

Under the Medical Care Act, medical practice can only be performed in medical institutions that are categorised as hospitals (with 20 or more beds) or clinics (with zero to 19 beds).

The Medical Care Act also provides for requirements for establishment permits (e.g., staff deployment standards, facility standards, and responsibilities of managers) for each category of hospitals (such as general hospitals, special functioning hospitals, regional medical care support hospitals, clinical research core hospitals, psychiatric hospitals and tuberculosis hospitals) and the names that hospitals can use.

The setting up of clinics requires notification if the applicant is a physician or dentist, or a permit if the applicant is a corporate body or is neither a physician nor a dentist.

In addition, medical institutions must be separately registered as insurance medical institutions to be included in the NHIS system.

iii Healthcare professionals

Healthcare professionals such as (1) physicians, (2) dentists, (3) pharmacists, (4) public health nurses, midwives, nurses and assistant nurses, and (5) others are regulated respectively under:

  1. the Medical Practitioners Act;
  2. the Dental Practitioners Act;
  3. the Pharmacists Act;
  4. the Act on Public Health Nurses, Midwives and Nurses; and
  5. other laws.

A graduate of a medical school (or medical department of a university) outside Japan, or a physician licensed outside Japan must be accredited by the MHLW to take the National Examination for Medical Practitioners.4 However, (1) a physician, dentist or nurse licensed outside Japan who visits Japan for purposes of acquiring medical knowledge and skills, or (2) a physician or dentist licensed outside Japan who visits Japan for purposes of teaching or researching medicine or dental medicine may provide medical services to the extent that those services are rendered within the scope of those purposes by obtaining a special permit from the MHLW.5

To our knowledge, foreign entities who approach the Japanese medical industry sometimes involve foreign medical practitioners in their research and development (R&D) or commercial activities. But the performance of any medical act in Japan always requires a licence or its equivalent under the Medical Practitioners Act.6


i Overview

Because of the information asymmetry between medical practitioners and their patients, as well as the physicians' expertise, the medical hierarchy and the locked-room nature of the medical profession, medical practitioners do not typically lose medical malpractice cases. In 2016, the average trial period of medical malpractice cases was approximately 24.2 months and their settlement rate was approximately 53.3 per cent, while the average trial period of civil cases (other than overpayment claims) was approximately 8.8 months and their settlement rate was approximately 34.7 per cent.7 This means that medical malpractice cases tend to end in settlement in over 50 per cent of the cases, after prolonged trial periods.

Technically, a 'reasonable causal relationship' between a negligent conduct and damages or death is not easy to establish. Therefore, Japanese courts have eased the plaintiff's burden of proof under various theories, such as 'violation of patient's expectation right' and 'possibility of patient's survival to a reasonable extent at the time of death', among others.

Moreover, punitive damages are not allowed under Japanese law, and the amount of damages paid to the elderly is generally not large.

ii Notable cases

In a decision issued in 2000, the Supreme Court adopted the concept of possibility of patient's survival to a reasonable extent at the time of death, that is to say, where the causal relationship between a doctor's negligent medical act or failure to act and a patient's death is not proved, but the possibility of the patient's survival to a reasonable extent at the time of death if medical services satisfying fair medical standards were rendered is proved, the doctor shall be liable.8

There have been two recent high-profile medical malpractice incidents in Japan. The first is the use of propofol, which is banned for use on children, on 63 children at the Tokyo Women's Medical University Hospital in 2014. The second is the high incidence of deaths in patients who underwent complex liver surgery by laparoscopic operation at the Gunma University Hospital in 2015. Both hospitals involved are 'special functioning hospitals' that provide advanced medical care, develop and evaluate advanced medical technologies, and provide advanced medical research. These incidents led to the eighth major revision of the Medical Care Act (the 8th Revision), which became effective on 1 June 2018, which reformed the governance of special functioning hospitals, including requiring due procedures for the appointment of hospital managers, establishment of an audit committee to ensure the safety of medical care, and establishment of a compliance system.


Various entities, including the government, public medical organisations, social insurance related entities, medical corporations, public benefit corporations, private school corporations, social welfare corporations, general corporation associations or foundations, stock corporations and individuals, can operate medical facilities such as hospitals and clinics; however, approximately 68.9 per cent of the hospitals in Japan are operated by medical corporations (as at 31 March 2019).9 A medical corporation is either a medical corporation association, which is an assembly of people, or a medical corporation foundation, which is an assembly of funds. A medical corporation association may be with or without equity. As at 31 March 2019, of 54,790 medical corporations, 39,263 were with equity.

When a medical corporation association with equity is dissolved, the residual assets will be distributed to the equity holders in proportion to their equity holdings. On the other hand, when a medical corporation association without equity is dissolved, the residual assets will be distributed to the national government, local governments or other medical corporations without equity.

In addition, when a member (and equity holder in almost all cases) of a medical corporation association with equity leaves the medical corporation by resignation or death, that member, or his or her heir, has the right to request the return of that member's equity. The amount to be returned is calculated by multiplying the then net asset value of the medical corporation association with the equity ratio. This calculation was upheld by the Supreme Court in a decision issued on 8 April 2010. As can be expected, the operation of a medical corporation association with equity is adversely affected when it must return a member's equity. Thus, the government encourages medical corporations with equity to convert into medical corporations without equity by providing time-limited tax incentives.

The conversion is done by the voluntary relinquishment by all members of their right to request for the return of their equity. The government hopes to convince members to give up that right through tax incentives, such as the deferral of and exemption from inheritance tax (on deceased members' heirs) and deemed gift tax (on the members who do not relinquish that right at the time of conversion, or even if they do relinquish, on the medical corporation itself that acquires benefits from the relinquishment by all the members), for conversions made from 1 October 2014 to 30 September 2017 (under certain strict requirements), and from 1 October 2017 to 30 September 2020 (with a relaxation of the strict requirements). Once a medical corporation with equity converts into a medical corporation without equity, however, it cannot reconvert into a medical corporation with equity. In practice, it is typical for members to weigh the tax incentives against the hope of a future sale that will monetise their equity.

One of the major policies of the Medical Care Act is that medical practice must be non-profit because (1) Japanese medical services are supported by the universal healthcare insurance backed by public funds and, thus, medical services should not be provided for profit, and (2) non-profit organisations have fewer incentives to take advantage of the information asymmetry between physicians and patients for profit and are, thus, a cost-effective way to monitor fraud by medical service providers. Because of the non-profit status of medical services:

  1. a licence to operate medical facilities is generally not given to for-profit organisations (with limited exceptions);
  2. medical corporations are prohibited from making dividend distributions (including de facto dividend distributions like rents proportionate to earnings); thus, any surplus of medical corporations can only be used for medical expenditures such as maintenance and improvement of medical facilities and salaries of employees and any remaining balance must stay within the medical corporations;
  3. the directors general of medical corporations must be physicians or dentists, with exceptions under specific permit from the relevant prefectural governor; and
  4. for-profit organisations such as stock corporations may make monetary contributions to medical corporations but cannot become members thereof (with limited exceptions).

In addition, directors of entities operating a medical facility are prohibited from concurrently serving as directors or employees of other for-profit entities with an interest in the establishment or operation of that medical facility.

Because of the foregoing restraints, for-profit organisations are less incentivised to make contributions to medical corporations, especially in the context of M&A to revitalise distressed ones. Prohibition of rents proportionate to the earnings of a hospital also restrains the flexible structuring of attractive products to securitise hospital real estate.

In a structure specific to family-owned medical corporations, a for-profit organisation called a 'medical services corporation', or an 'MS corporation', is often established by a family member of the founder physician, and provides to the medical corporation such services as laundry of linen, leases of medical devices and hospital or clinic buildings, procurement of medical goods and drugs, and provisions of accounting and other administrative services. There are suspicions that surpluses from medical services are paid to MS corporations for those services to circumvent the principle of non-profit status of medical institutions. The current arrangement with MS corporations is expected to be affected by the requirement of the 7th Revision for the auditing of the financial statements of medical corporations and filing requirements for, and public disclosure of, transactions with closely related entities.


Commissioning is a process where the delivery of certain public services to be provided by the public sector is commissioned to the private sector, whereas procurement is a process where the public sector procures from the private sector goods and services it needs to deliver public services. In Japan, medical services are provided by private entities, which are not subject to commissioning and procurement procedures applicable to governmental entities.


i Restrictions on advertising of medical services

Before the 8th Revision, there were two different sets of restrictions on the advertising of medical services: (1) one for advertising media such as advertising inserts, TV commercials and signboards under the Guidelines for Advertisements for Medical Services, and (2) another for advertisements on websites under the Guidelines for Home Pages of Medical Institutions.

Before the 8th Revision, generally, no one was permitted to advertise any matter with respect to medical services other than certain limited information (such as the name of a physician or dentist, his or her clinical department, and medical services to be rendered). False advertising was subject to penalties (direct penalties), while comparative advertising, exaggerated advertising, objective-truth-not-proven advertising and advertising with content in violation of public order and morality (collectively, exaggerated advertising) were subject to orders for suspension or correction from the relevant prefectural governor but only subject to penalties for violation of such orders (indirect penalties). If there was a threat of false or exaggerated advertising, the prefectural governor was entitled to request the submission of a report and to have its officials enter and inspect the sites. Advertising on the websites of medical institutions was not treated as constituting 'advertisements', which were prohibited under the Medical Care Act, and therefore no penalties were imposed for violations of the Guidelines for Home Pages of Medical Institutions.

However, because numerous consumer problems related to aesthetic medical services arose from advertising on medical providers' websites, the 8th Revision defined advertising under both items (1) and (2) above as statutory 'advertisements' subject to direct penalties for false advertising, indirect penalties for exaggerated advertising (to the definition of which the 8th Revision added advertising by use of patients' experiences on a subjective or hearsay basis and advertising by use of misleading pictures before and after medical treatments), and site inspection by the relevant prefectural governor. The 8th Revision also clarified the limited cases that are not subject to the aforementioned limitations on advertisements, taking into account medical treatments that are not covered by the NHIS or other information that patients need to know. The Guidelines for Home Pages of Medical Institutions were integrated into the Guidelines for Advertisements for Medical Services on 1 June 2018.

Healthcare providers and their commissioned advertising agencies and affiliate marketers may also be subject to other advertising regulations under other laws of more general application, such as the Act against Unjustifiable Premiums and Misleading Representations, the Pharmaceuticals and Medical Devices Act (PMDA),10 the Health Promotion Act, and the Act on Unfair Competition Prevention.

ii Restrictions on marketing and promotion activities toward healthcare providers and professionals

Medical institutions and universities (including healthcare professionals) not only buy from pharmaceutical and medical device companies, but also collaborate with these companies for medical and pharmaceutical research, safety measures, and reliefs from adverse drug reactions, and arrangements are often accompanied by monetary payments in return for their contribution.

The MHLW and the Pharmaceuticals and Medical Devices Agency11 are the principal regulatory authorities under the PMDA. In addition, the Fair Trade Commission and the Consumer Affairs Agency oversee those relations through the relevant self-regulatory organisations12 pursuant to the Fair Competition Code Concerning Restrictions on Premium Offers in the Ethical Pharmaceutical Drugs Marketing Industry and the Fair Competition Code Concerning Restrictions on Premium Offers in the Medical Devices Industry, both of which are based on the Act Against Unjustifiable Premiums and Misleading Presentation (AUPMP).13

At an industry self-regulation level, pharmaceutical and medical device companies have made efforts to make these relations more transparent through their industry associations and industry regulations based on high ethical standards. These industry regulations include corporate activity charters, compliance programme guidelines, codes of practice, promotion codes and transparency guidelines. It should be noted, however, that these industry regulations are not legally binding and violations thereof are not statutorily penalised.

On 19 March 2019, a bill to amend the PMDA and other relevant laws covering the following, inter alia, was submitted to the Diet:

  1. establishment by proprietors of pharmacies and pharmaceuticals and medical device companies of a system to ensure compliance with laws and regulations on pharmaceuticals and medical devices;
  2. enhancement of the existing system for importation certificates for unauthorised medicines and medical devices from overseas, and strengthening the authority of drug enforcement officers; and
  3. introduction of a surcharge system for false or exaggerated advertising regarding pharmaceuticals and medical devices, which will (1) impose a surcharge equal to 4.5 per cent of the related sales of violators, (2) deduct 3 per cent of the related sales from that 4.5 per cent surcharge, if the same advertising is also subject to another surcharge system under the AUPMP, and (3) enable violators who file a leniency application with the MHLW under certain conditions to receive a 50 per cent deduction of the surcharge.


The following possible solutions to the significant issues pointed out in Section I are currently in progress or being considered.

i Uneven distribution of physicians in regional areas and among departments

On 6 July 2018, the Act on the Arrangement of Related Acts to Promote Work Style Reform was promulgated, setting maximum limits on overtime hours. However, its application to physicians has been deferred until April 2024. When the new law is applied, physicians' overtime hours will be limited to 960 hours per year, with certain exceptions up to 1,860 hours per year, where a physician's duty to respond to emergencies, the public nature of medical care, the unpredictability of diseases, the physician's expertise and training, and innovations in medical treatments are balanced.

On 1 April 2019, to tackle the uneven distribution of physicians in regional and practice areas, the following amendments to the Medical Care Act and the Medical Practitioners Act took effect:

  1. introduction of a new system regarding the MHLW's accreditation of physicians with certain working experience in regional areas facing a shortage of physicians and the evaluation of such physicians as managers of 'regional medical care support hospitals';
  2. establishment of 'plans to procure physicians' under the Medical Care Plans, through a PDCA cycle by prefectural governments, and enhancement of the cooperative functions of the councils for regional medical services in the prefectures;
  3. reinforcement of measures for procuring physicians through training programmes, including having regional quota for admissions to medical schools in universities; and
  4. promotion of functional differentiation and cooperation among outpatient hospitals inside and outside each secondary medical service area.

ii Ageing and deterioration of medical facilities

Solutions to ageing and deteriorating medical facilities include complete reconstruction and large-scale repairs (including renovation for earthquake-resistant structures) of these facilities. It is anticipated that these necessary repairs or reconstruction will be financed primarily through debt financing by the Welfare and Medical Service Agency14 or other financial institutions and secondarily through asset financing, rather than equity funding, because of the low return on investment because of the non-profit status of medical practice in Japan.

As to asset financing such as securitisation of real estate for hospitals, on 26 June 2015 the Ministry of Land, Infrastructure and Transport issued the Guidelines Concerning REITs Investing in Real Estate for Hospitals, which took effect on 1 July 2015. The Guidelines were issued after discussions with various interested parties, including the MHLW and the Japan Medical Association (JMA),15 and placed importance on healthcare business operators and internal management systems in the licensing requirements for asset management companies of REITs. It bears mentioning that the securitisation of hospital real estate essentially requires a separation of the ownership of fundamental assets and the operation of the healthcare business, which is different from the traditional view held by originators of hospital real estate that medical assets should be owned and operated by medical practitioners.

Notwithstanding the Guidelines, there has not been much progress in investments by REITs listed on the Tokyo Stock Exchange in hospital real estate. The first two deals (namely the acquisitions of Niigata Rehabilitation Hospital and Senri Chuo Hospital, both in the form of trust beneficial interest) were made on 10 October 2017 and 11 January 2019 respectively, by Healthcare and Medical Investment Corporation. But no other listed REITs have acquired hospital real estate. One possible reason for this is the JMA's constant vigilance against the entry of 'funds' that represent for-profit entities, which is not consistent with the non-profit status of medical practice in Japan. This approach creates anxiety among healthcare business operators about the possible discontinuation of their business because of the loss of hospital real estate in the event of non-payment of rent. On the other hand, REITs themselves may not be prepared to accept risks associated with advanced acute or acute care facilities, including the possibility that medical revenues may be less stable compared with those from recovery phase facilities and medical accidents, which may harm their reputation.

New approaches to connect the healthcare industry and the fund industry are crucial. These approaches include (1) eliminating the old-fashioned view that the ownership of hospital assets and the practice of medicine should be one and the same, (2) encouraging healthcare business operators to establish and implement a more enhanced and transparent governance system, and (3) encouraging fund investors to understand the healthcare industry and not seek excessive returns through environmental, social and governance investing, socially responsible investing or 'impact investing'.

iii Family-oriented governance of medical corporations

On 2 April 2017, Japan started a new corporate system called 'Corporations Promoting Regional Medical Cooperation' under the 7th Revision. Under this system, general incorporated associations that meet certain criteria may be accredited by prefectural governors as Corporations Promoting Regional Medical Cooperation. These criteria include (1) establishing a policy of providing functional differentiation of, and cooperation among, healthcare services within a healthcare service area and (2) engaging in activities involving non-profit organisations that agree with this policy and participate in meeting hospital bed quotas and cooperative purchasing of pharmaceuticals and medical devices, exchange of personnel, and R&D among those organisations.

However, as at 1 April 2019, there are only eight such accredited corporations. They include Japan Sea Healthcare Net Corporations Promoting Regional Medical Cooperation, which was accredited on 1 April 2018. This corporation is unique in that it is managed by an independent administrative agency that was established in April 2008 as a result of a merger of two hospitals that were sponsored by different local governments. This merger represents a 'hard-type' business integration initiated by medical organisations that are sponsored by and reliant on local governments. It bears studying whether that kind of hard-type business integration will become a preferred choice of local-government-sponsored medical organisations, given that, according to the latest survey reports,16 approximately 90 per cent of them were in deficit without local government funding and hard-type business integration may be unavoidable.

On the other hand, for private medical corporations, we expect that 'soft-type' solutions may be more easily employed than hard-type solutions because the integration of varied human resources and payroll systems generally takes considerable time and effort. These soft-type solutions include (1) business alliances or management integrations of medical corporations, and (2) M&A transactions where the purchaser acquires controlling power (and if the target is a medical corporation with equity, the purchaser also acquires the equity).

We also expect that, like many other legal entities in Japan, medical institutions will start enhancing their governance systems such as safety, compliance and whistle-blower systems.

iv New industrial technologies

The most recent major amendments to the primary data protection law in Japan, the Act on the Protection of Personal Information (APPI), became completely effective on 30 May 2017. The amended APPI strictly restricts the utilisation of patients' medical history and other sensitive information referred to as 'special care-required personal information'. In this regard, a special but related law, the Act on Anonymised Medical Data to Contribute to R&D in the Medical Field, became effective on 11 May 2018 with the aim of balancing industrial needs and privacy protection. Another recent law, the Act On Clinical Research, which became effective on 1 April 2018, safeguards the quality of, and protects data subjects in, certain types of clinical research called 'Specified Clinical Research', by requiring researchers to comply with certain clinical research standards, submit research implementation plans and be reviewed by certified clinical research review committees, and by requiring the marketing authorisation holder to disclose conflicts of interest arising from the provision of research grants.

In March 2018, the MHLW released the Guidelines for the Appropriate Implementation of Online Medicine, followed by the related Q&A, and the Notification of the Handling of Inappropriate Medical Practice of Online Medicine on 26 December 2018. These guidelines cover the minimum standards and recommendations for (1) online medicine (i.e., telemedicine on a real-time basis), including medical examination, diagnosis, and provision of diagnostic results and prescription through information and communication electronics devices on a real-time basis, and (2) online encouragement of visits to physicians who possess the minimum required medical judgement to refer patients to appropriate specialists by using information gathered through interviews or medical questionnaires using information and communication electronics devices on a real-time basis, but without, in any event, making a medical diagnosis, prescribing medicine or otherwise conducting medical practice. They will be revised every year, in light of the progress in technologies and other developments. In January 2019, LINE Corporation and M3, Inc announced a joint investment to launch LINE Healthcare Corporation to develop online healthcare businesses.

It is hoped that these new laws, which aim to address issues arising from new industrial technologies, will not only create legislative and administrative regulations, but also strengthen self-regulation and cooperation between the non-profit healthcare industries and the for-profit industries.

v Possibility of inbound or outbound investments into or from, or business partnerships with, healthcare providers

Inbound investment by foreign entities by way of contributions in medical corporations in Japan is not likely to be permissible in the near future. The JMA has taken the view not only that for-profit organisations should not have any controlling power over medical corporations, but also that foreign entities should not have such power.

Inbound investment by way of shares of peripheral profit companies (usually family-owned companies) is possible under certain procedures under the Foreign Exchange and Foreign Trade Act. In any case, M&A purchasers who have their own R&D or commercial activities that involve medical practice in Japan must have the necessary licence under the Medical Practitioners Act before they may perform medical acts on legal residents in Japan.

In contrast, outbound investments by Japanese medical corporations into shares of foreign medical entities are permissible, subject to compliance with notifications issued by the MHLW,17 as long as (1) their overseas operations will not adversely affect their original business of running hospitals, clinics, long-term-care health facilities or long-term-care medical centres, (2) the aggregate investments in local entities are within the retained earning reserves on their latest balance sheet prepared in accordance with the Medical Corporation Accounting Standards, and (3) they make prescribed prior and periodic reports to the MHLW.


The world has been watching Japan as it faces enormous and unprecedented challenges in healthcare ahead of any other country because of Japan's twin population problems of inevitable ageing and persistent population decline. As Japan continues to confront and overcome these mounting and increasing difficulties, the medical, healthcare, nursing care and related industries will need the ever increasing and ever crucial support, resourcefulness and initiative of investors, innovators and professionals, including lawyers, especially in the context of M&A, financing, governance, restructuring and rehabilitation, to navigate the growing needs of Japan's citizens.

2 See 'The Third Interim Report' from 31 May 2018, prepared by the Physicians Supply and Demand Subcommittee under the Healthcare Providers Supply and Demand Review Committee (set up by the Health Policy Bureau of the MHLW).

3 Secondary medical service areas are areas determined by each prefectural government in its Medical Care Plan as enabling the provision of relatively highly specialised medical services including hospitalisations. In contrast, primary medical service areas provide daily medical services that generally correspond to minimum administrative districts, and tertiary medical service areas are those determined by each prefectural government in its Medical Care Plan as enabling the provision of advanced medical services that generally cover the prefecture concerned, except Hokkaido Prefecture and Nagano Prefecture, which are large and are divided into multiple tertiary medical service areas.
