The Employment Law Review: Japan


The laws in Japan governing collective labour relationships are the Labour Union Act (LUA) and the Labour Relations Adjustment Act. Regarding individual labour relationships, there are laws protecting minimum working conditions, such as the Labour Standards Act (LSA), the Minimum Wages Act, the Industrial Safety and Health Act (ISHA) and the Industrial Accident Compensation Insurance Act. These laws are traditional Japanese labour laws established after World War II and based on the Constitution of Japan.

The Labour Contract Act (LCA), enacted in 2007, sets out basic regulations on employment agreements. The revision of the LCA (effective from April 2013) includes important amendments for fixed-term employment. The Equal Employment Opportunity Act (EEOA)2 entered into effect in 1986 and has been revised several times. Since 2007, the EEOA has broadened protections for employees so that both male and female employees will not suffer any disadvantages based on their gender. Employees' rights are also expanded by other laws, such as the Child Care and Family Care Leave Act3 and the Part-time Employment Act (PEA).4 In addition, the Worker Dispatch Act (WDA), enacted in 1985 and amended in 1999, extended the scope of occupations that were covered by the worker dispatching system. As a result, the worker dispatching system was considered a social problem, so the WDA was further amended in 2012 and in September 2015.

Each labour law has a different supervision and conflict resolution system, so the system as a whole is complicated. The LUA stipulates a system of labour relations commissions, whereby a local labour relations commission (established in each prefecture) and its supervising agency, the Central Labour Relations Commission, conduct mediation, conciliation and arbitration to settle collective labour disputes.

In contrast, ordinary courts settle individual labour disputes. Additionally, since the inception of the labour tribunal system in 2006, labour tribunals have also been competent to settle these types of disputes. Local labour departments (government agencies) also conduct mediations to settle these disputes.

The Labour Standards Inspection Office (LSIO) is the supervisory agency with regard to the LSA, the Minimum Wages Act, the ISHA and the Industrial Accident Compensation Insurance Act.

Local labour bureaus are the supervisory agencies with regard to the EEOA, the PEA and the WDA.

Year in review

As part of the process of work-style reforms in Japan, the LSA and some other acts have been amended, and new measures for the 'correction of working long hours, including an upper limit for overtime work of the “36 agreement” with penalties' were enacted on 1 April 2019 (with respect to small and medium-sized enterprises, they will be enforced from 1 April 2020).

Regarding the '36 agreement' (a labour management agreement stipulated in Article 36 of the LSA), which regulates limits for overtime and holiday working hours, a measure of stipulating the upper limit for overtime work with penalty was introduced under the aforementioned measure. Under the new stipulation, overtime is capped at 45 hours per month and 360 hours per year in principle. Even when a 'special clause' applies, which can be used up to six times (i.e., six months) a year, applies, the maximum limits on overtime and holiday working hours are 100 hours per month and an average of 80 hours per month over two to six months; furthermore, overtime working hours must be fewer than 720 hours per year. However, the actual effect of the measure to limit overtime work is doubtful so far.

Even in leading enterprises, cases of mental disorder and even death attributed to long working hours or stress in the workplace have been reported. At one electronics manufacturer, a senior employee who was putting pressure on a junior employee said to the employee: 'You should die.' The junior employee later committed suicide. This case was sent to the prosecutor's office as a criminal offence (i.e., solicitation of suicide).

It was determined that the use of this kind of language and behaviour by people in superior positions in the workplace that is beyond the necessary level for work purposes or is socially unreasonable will be defined as 'power harassment' in the Labour Policy General Promotion Act amended in June 2019 (the amended Act will be enforced on 1 June 2020). With this amendment, companies will be required to take measures to prevent any such power harassment from impairing the working environment for employees.

Companies have already been obliged to take measures to prevent sexual harassment and maternity harassment. With the inclusion of the prevention of power harassment as of June 2019, it has been confirmed that the prevention of harassment in the workplace is a significant issue for companies.

Significant cases

The classifications of 'employee' and 'independent contractor' are currently at issue in Japan. The following decision by the Central Labour Relations Commission (CLRC) is worthy of note in this respect.


The CLRC judged that members of a convenience store (franchise) are not categorised as employees of the franchisor under the LUA, and the fact that the franchisor did not hold a collective bargaining with the members of franchise is not regarded as an unfair labour practice under the LUA. The outline of the case is as follows:

  • A member (Member A) of a convenience store (the store in which Member A operates, hereinafter, the franchise) entered into a franchise contract with Seven-Eleven Japan, the company that operates that chain of convenience stores.
  • Member A is responsible for the management of the franchise, including:< >the procurement and management of funds;the recruitment of employees;determining working conditions; anddetermining the methods for the purchase and sale of goods.Seven-Eleven Japan sends a field counsellor to Member A about twice a week, and provides guidance and advice on the overall management of the franchise.
  • Member A joined a labour union. The union requested Seven-Eleven Japan to enter into a collective bargaining agreement, which Seven-Eleven Japan rejected. The union therefore filed a case with the local labour relations commission. On 13 March 2014, the labour relations commission held that Member A is categorised as an employee under the LUA, and that the refusal of Seven-Eleven Japan for collective bargaining is regarded as an unfair labour practice under the LUA. Seven-Eleven Japan appealed for review to the CLRC.
  • The CLRC rescinded the dispositions of the local labour relations commission and dismissed the case filed by the union, holding that ‘Member A cannot be regarded as an employee under the LUA in relation to Seven-Eleven Japan’. The reasons stated are as follows:
    • Member A raises funds and bears the costs of the franchise's business operation. In addition, the loss and profit of the franchise belongs to Member A. Member A utilises the labour force by employing employees. Personnel management at the franchise is at the discretion of Member A, as manager of the franchise. Therefore, although there are certain restrictions on the franchise's business, such as the management of funds, the purchase of goods, and the business days and business hours, Member A is regarded as an independent contractor (entrepreneur) with considerable discretion.
    • It cannot be said that Member A performs labour for Seven-Eleven Japan by receiving the order of working time and workplace from Seven-Eleven Japan. While Member A has received the advice and guidance of manuals from Seven-Eleven Japan, it cannot be said that this has binding power, except in the case of a breach of contract. Thus, Member A does not supply labour under the command and supervision of Seven-Eleven Japan.
    • The disparity between Member A's and Seven-Eleven Japan's bargaining power should not be considered as the bargaining ability gap between employers and employees, but rather that the disparity is the bargaining ability gap between business operators. This gap should be solved under the Fair Trade Law.
    • In total consideration of these matters, Member A cannot be regarded as an employee under the LUA who is incorporated into the business organisation of Seven-Eleven Japan.

Basics of entering into an employment relationship

i Employment relationship

An employment contract is established when an employer and a job applicant agree that (1) the job applicant shall work for the employer and (2) the employer shall pay a salary to the job applicant as consideration. If the employer has in place working rules that stipulate reasonable working conditions and has informed its employees of those rules, the contents of an employment contract shall be based on the working conditions provided by the working rules without the requirement of consent from the job applicant. A job applicant and an employer may enter into or change, by agreement, an employment contract that includes working conditions that differ from those under the working rules. However, any parts of an employment contract that stipulate working conditions that do not meet the standards established by the working rules shall be invalid. In this case, the invalid portions shall be governed by the standards established by the working rules.

There is no statutory requirement concerning the form of an employment contract, so an employer and a job applicant may orally enter into an employment contract. However, to allow the job applicant to understand his or her rights and duties under the contract, the employer must notify him or her in writing of certain employment conditions5 before or upon entering into the employment contract.6 The employer can fulfil this requirement by giving the applicant a written employment contract or by providing a copy of its working rules.

Fixed-term employment is lawful, but the term of the agreement cannot be longer than three years, except in limited circumstances.

ii Probationary periods

Although there is no regulation concerning probationary periods, an employer may set a limited probationary period based on case law in Japan. Many employers use probationary periods to train and to evaluate their employees to determine whether they should be retained as fully fledged employees.

An employer generally sets forth probationary periods in its working rules. Generally, probationary periods range from one to six months and are typically three months. Extremely long probationary periods will be void because of a violation of public policy.

It is generally understood that the usual probationary period is designed to reserve the employer's right of cancellation. The employer may dismiss an employee on probation less strictly than a regular employee; however, even during the probationary period, 'reasonable and socially acceptable' grounds are required to dismiss an employee. This means that an employer is required to show a lack of fitness of an employee based on facts (e.g., low job performance ratings and unsatisfactory attitudes) to properly exercise its reserved cancellation rights.

iii Establishing a presence

Whether a foreign company is required to register will be depend on its intended business in Japan. If it intends only to conduct preparatory or supplemental tasks (e.g., market surveys and collecting information), it may establish its representative office in Japan without any registration. However, if it intends to operate its business continuously in Japan, it must register with the relevant legal affairs bureau. In this case, while the foreign company does not have to establish a branch office in Japan, it must at least register its representative or its branch office (if any) in Japan.

Unless a foreign company intends to operate its business continuously in Japan, it may engage an independent contractor in Japan that does not require registration. An independent contractor will constitute a permanent establishment (PE) of the foreign company under certain conditions, such as the contractor being authorised to conclude contracts on behalf of the foreign company in Japan. While there are exemptions for independent contractors under Japanese taxation laws, if a foreign company has its PE in Japan, its Japanese-sourced income will be subject to corporate tax.

There are four types of insurance that a company is obliged to have: workers' accident compensation insurance, employment insurance, health insurance and nursing care insurance, and employees' pension insurance.

Salary income is subject to withholding tax under the Income Tax Act. Under the withholding tax system, a payer of salary income in Japan must calculate the amount of income tax payable, withhold the amount of income tax from the income payment and pay it to the government.

Restrictive covenants

Given the personal, continuous character of an employment contract, a relationship of trust between the parties is required. In more concrete terms, each party is required to act in good faith in consideration of the other's interest. Therefore, during the term of employment, an employee shall undertake obligations to keep trade secrets, to refrain from competitive activities and not to damage the employer's reputation or confidence even if there is no provision about the obligations under any employment contract or working rules.

By contrast, an employee has the right to change his or her job, which means that if the employer wants its employees to undertake post-termination non-compete obligations, it must enter into such an agreement with the employees or have corresponding working rules, both of which should set forth the obligations. Non-compete obligations are direct restrictions on a former employee's freedom to choose his or her occupation, so courts will decide their enforceability based on a variety of factors, such as whether the duration and scope of the obligations are clearly stated in an agreement or working rules, and whether additional and sufficient financial compensation is provided to the former employee.


i Working time


The LSA stipulates overly rigid regulations on working hours. In principle, an employer must not require or approve of employees working more than eight hours a day or 40 hours a week (excluding rest periods) without a labour management agreement.7 These are generally known as statutory working hours. If an employer violates this regulation, it will bear criminal liability.8

If an employer wants to require employees to work more than the statutory working hours, it must enter into a labour management agreement either with a labour union (if any) or, if a union does not exist, an employee who represents the majority of employees in the workplace, and then notify the relevant government agency of the agreement.9

The Work Style Reform Act took effect on 1 April 2019. According to this Act, even if a labour management agreement is executed, overtime will, in principle, be capped at 45 hours per month and 360 hours per year. It will be possible for employers to require employees to work more hours when special circumstances exist based on the labour management agreement. However, even under these special circumstances, the maximum limits for overtime must be less than 100 hours (including hours for legal holiday work) per month, an average of 80 hours (including hours for legal holiday work) per month over two to six months, and 720 hours per year.

The maximum limits on overtime working hours can be summarised as follows:

In principal45 hour/month and 360 hours/year
In an extraordinary special circumstance720 hour or less/year (overtime only)
Less than 100 hour/month (both overtime and holiday work)
Average of 2 to 6 months 80 hours or less/month (both overtime and holiday work)
Month with more than 45 hours of overtime work should be limited to 6 times/year.


The LSA stipulates certain modified systems of working hours, such as flexitime and annual, monthly or weekly modified systems. Under these systems, an employer may require its employees to work beyond the statutory working hours to the extent permitted by law.


Certain employees, such as those in management, are exempted from the regulations on statutory working hours.10 This means that an employer may require the exempted employees to work in excess of the statutory working hours without entering into a labour management agreement.

ii Overtime

The LSA does not require an employer to pay its employees a salary based on working hours. However, it is understood that, in practice, wages and working hours are associated when it comes to overtime pay. Under certain conditions, an employer may let its employees work overtime, with the LSA requiring the following minimum salary premiums for all employees, except those who are exempted from the regulations on statutory working hours.

Work in excess of statutory working hours25%
Work in excess of statutory working hours exceeding 60 hours in a month50%
Work on statutory days off35%
Work performed late at night (between 10pm and 5am)25%
Work performed late at night in excess of statutory working hours50%
Work performed late at night in excess of statutory working hours exceeding 60 hours in a month75%
Work performed late at night on statutory days off60%

Employees who are exempted from the regulations on statutory working hours (e.g., employees in management roles) are entitled to a minimum premium of 25 per cent for work performed late at night (between 10pm and 5am). However, these employees are not entitled to receive any other premiums.

iii Prohibition of unreasonable treatment (employment terms, working hours, etc.)

Currently, Article 20 of the LCA provides that working conditions for fixed-term employees should be balanced with those for open-term employees under the same employer to improve working conditions for irregular workers.

However, on 1 April 2020, Article 20 of the LCA will be abolished, and the Act on Improvement, etc. of Employment Management for Part-Time Workers will be amended to cover managing the employment for fixed-term employees. (The name of the Act will be changed to the Act on Improvement, etc. of Employment Management for Part-Time Workers and Fixed-Term Workers.) As this result, working conditions for part-time employees and fixed-term employees should be balanced with those for open-term employees under the same employer. In addition, under certain special circumstances, working conditions for part-time employees and fixed-term employees should be equal to those for open-term employees under the same employer. With regard to Article 20 of the LCA, the Supreme Court issued two important decisions on 1 June 2018, and many other decisions have been issued in district courts and appeal courts. These decisions will become case law when interpreting relevant Articles under the Act on Improvement, etc. of Employment Management for Part-Time Workers and Fixed-Term Workers.

The WDA has also been amended to improve the working conditions for dispatched workers. Under new regulations, working conditions for dispatched workers should be in line with those for employees at a company that accepts a dispatched workers, unless a labour management agreement exists between a staffing company and the representative of its dispatched workers. These regulations will become effective from 1 April 2020.

Foreign workers

There is no limit on the number of foreign workers that an employer can employ. Japanese employment laws are applicable to foreign workers who are employed and work in Japan regardless of whether their employer is a foreign company or a domestic company.

Additionally, an employer must not use the nationality of any employee as a basis for engaging in discriminatory treatment concerning certain working conditions, such as wages and working hours.11

When an employer enters into an employment contract with a foreign person, other than a special permanent resident, it must notify the relevant job placement office of key information about the person, such as name, residency status and date of birth. The employer is also required to give notice to a relevant job placement office of the person's retirement.

Any foreign national who enters Japan to work must obtain a working visa at a Japanese diplomatic mission abroad. Also, any foreign national must generally receive landing permission when he or she arrives at a port of entry, a time when his or her residency status and period of stay in Japan will be determined. The foreign national can conduct activities within its residency status. The foreign national can only reside in Japan for the agreed period of stay. A foreign national who wishes to continue conducting the same activities in Japan within his or her current residency status beyond the period of stay must apply for an extension no later than the last day of the period.

There are four types of insurance that are obligatory for employers in Japan, as mentioned in Section IV.iii, all of which also apply to foreign workers.

All individuals, regardless of nationality, are classified as either residents or non-residents under Japanese tax laws. In general, residents have an obligation to pay income tax on their worldwide income (including salary). By contrast, non-residents are obliged to pay income tax on any income from domestic sources (including salary for employment in Japan).

Global policies

The adoption of working rules is mandatory for any employer who hires 10 or more employees on a continuing basis. The employer must submit its working rules to the relevant local LSIO.12 When establishing its working rules, an employer must seek the opinion of either a labour union (if applicable) or, if there is no union in the workplace, an employee that represents the majority of the employees in the workplace. When submitting its working rules to the relevant local LSIO, the employer must attach a document stating the opinion of the labour union or employee representative.13

The working rules must include the following information:14

  1. working hours (including holiday, leave, shift changes, breaks, and the start and end of the working day);
  2. wages (including the methods for determination, calculation and payment of wages, and the dates for closing accounts for wages and for payment of wages); and
  3. termination (including grounds for dismissal).

Working rules must also cover the following if the employer has a policy relating to any or all of these matters:

  1. termination allowances (including the scope of covered employees, methods for determination, calculation and payment of termination allowances, and the dates for payment of such allowances);
  2. special and minimum wages;
  3. the cost to be borne by employees for food, supplies or other expenses;
  4. safety and health;
  5. vocational training;
  6. accident compensation and support for an injury or illness that does not arise during the course of employment;
  7. commendations and sanctions; and
  8. other matters applicable to all employees at the workplace.

The working rules must not infringe any laws and regulations or any collective agreement applicable to the workplace in question.15

To amend working rules, the employer must request an opinion on its amendment from either a union or, if there is no union in the workplace, an employee who represents the majority of the employees in the workplace. The employer and the employees may, by agreement, amend the working rules. However, if (1) the employer informs its employees of changes to working rules, and (2) the changed working rules set forth reasonable working conditions in light of relevant circumstances (such as disadvantages to be incurred by the employees, the need for the change, the contents of the changed working rules and the status of negotiations with a labour union or a representative employee), the employer may amend its working rules without the employees' consent.

Parental leave

i Maternity leave

If a woman requests to take pre-childbirth leave when she is due to give birth within six weeks (or within 14 weeks in the case of a multiple birth), the employer is not permitted to require the employee to work during this time. Further, an employer cannot require a woman to work for eight weeks after childbirth (post-childbirth leave). However, this does not prevent an employer from permitting a woman to return to work sooner, when she has requested to do so, when certain requirements are met. In this case, the mother may return to work six weeks after childbirth.

ii Parental leave

An employee can request parental or childcare leave to care for a child less than one year old (or, in certain situations, less than one and half or two years old).

The employer may not refuse a request for childcare leave by any employee except those who (1) are employed for a specified term who meet certain conditions, (2) are employed on a per diem basis, and (3) belong to certain categories as specified in a labour management agreement made with a union or an employee representing a majority of the employees.


When employing foreign workers, an employer is not required to provide the worker with relevant documents (e.g., working rules and an employment agreement) in a language that he or she understands. However, to avoid conflicts, it is appropriate to explain key working conditions in a language comprehensible to foreign workers so that they can understand the terms and conditions of their employment contracts. Furthermore, an employer should display warning letters and health and safety rules in the workplace, both written in languages employees understand. If an industrial accident happens under a situation where there is no such display at a workplace, the situation will be regarded as evidence that an employer has not complied with its duties of safety and of safety education.

Employee representation

There is no definition of 'employee representation' under Japanese law. However, in certain situations, the LSA requires that an employer hear an opinion of or enter into a labour management agreement with either a labour union organised by a majority of the employees at a workplace (where such a union exists) or a person representing the majority of the employees at a workplace (where a union does not exist). While, in practice, the union or representative is referred to as an employee representative, this is very different from the works councils established and regulated in many European countries. When the employees at a workplace select a person to represent them, the person must be selected through a democratic process. Further, the employees cannot select a person in management as their representative. The employee representative is an ad hoc representative, so, in general, there is no term for the representative.

On the other hand, where an employer enters into a collective agreement concerning working conditions, a labour union will be party to that agreement. The Constitution of Japan guarantees workers' right to organise, and to bargain and act collectively, so a labour union must remain independent from an employer. In contrast to the United States and Europe, corporate unions are more popular than industry unions in Japan. Once a collective agreement is executed, any employment agreement that does not meet working conditions under the collective agreement will be void and replaced with the collective agreement. In a case of collective bargaining, an employer must negotiate in good faith with a labour union.

Employee representation (protected concerted activity)

Data protection

i Requirements for registration

Data protection in Japan is governed by the Act on the Protection of Personal Information (APPI), which was amended on 3 September 2015. The amendment included clarification on the definition of 'personal information', the establishment of the Personal Information Protection Commission and the introduction of provisions relating to sensitive data. There is no required registration in relation to data protection under Japanese laws.

When handling personal information, a company shall, as far as possible, specify the purpose for its use of personal information (the purpose).16 In principle, no company can handle personal information beyond the scope necessary to achieve the purpose without obtaining the prior consent of the data subject.17

When acquiring personal information, a company must promptly notify the person of, or publicly announce, the purpose, unless the company has already publicly announced it.18 In addition, when a company directly acquires personal information from a person in writing, the company must expressly show its purpose to the person in advance.19

A company must not, in principle, provide any personal data to any third parties without obtaining the prior consent of the person.20

A company must keep personal data accurate and up to date within the scope necessary for the achievement of the purpose. Once the purpose is achieved, a company must delete personal data without delay.21 Also, a company must take necessary and proper measures for the prevention of leaks, loss or damage, and for other security control of the personal data.22 A company must exercise necessary and appropriate supervision over its employees to ensure the security control of the personal data.23

ii Cross-border data transfers

A company must, in principle, obtain the prior consent of the person (the data subject) when it provides the data subject's personal data to any third party.24 The same shall apply for cross-border transfers of personal data.25

A company does not have to obtain the prior consent of the data subject in cases that are not regarded as the transfer of personal information to a third party.26 The same shall apply for the cross-border transfer of personal data if a company provides personal data to (1) any third party in a foreign country that has regulations for personal information protection at the same level as Japanese regulations, or (2) any third party in a foreign country who puts into place a system compliant with the standards prescribed by rules of the Personal Information Protection Commission as is necessary to continuously take measures corresponding with measures that business operators handling personal information ought to carry out pursuant to certain provisions under the APPI with regard to the handling of personal data.27

iii Sensitive data

The amendment of the APPI defines sensitive data as personal information that contains descriptions that have been specified by Cabinet Order to require special consideration in handling so as to avoid any unfair discrimination, prejudice or other disadvantage to an individual based on his or her race, creed, social status, medical history, criminal records or the fact that a person has incurred damages through an offence, etc.28 A company must not acquire sensitive personal information without obtaining the data subject's consent to do so, except in certain circumstances.29

Certain guidelines also set forth additional rules concerning sensitive personal information, such as information relating to race, ethnic group, social status, family origin, income and medical records. Further, if a company abusively uses such sensitive information, this may be regarded as a violation of privacy or an invasion of personal rights, in which case the company may be held liable for damages arising from the violation or invasion.

iv Background checks

As an employer has the freedom to employ persons of its choosing, it may collect personal information about applicants (such as information relating to their credit records), to a reasonable extent, as part of a background check. However, when collecting sensitive data, such as criminal records, an employer must obtain the applicant's consent to do so.

The collection of sensitive data needs to be carried out by commonly accepted proper methods and care must be taken to respect applicants' privacy.

Discontinuing employment

i Dismissal

As a general rule, employment will only be terminated for cause by an employer in Japan. There is no concept of termination 'at will'.

Causes for dismissal include poor performance, repeated misconduct, serious misconduct, redundancy and medical incapacity. However, an employer's right to dismiss an employee is severely restricted. Article 16 of the LCA stipulates that a dismissal will, if it lacks objectively reasonable grounds and is not considered to be appropriate in general societal terms, be treated as an abuse of rights and be invalid.

It is considered that dismissal because of poor performance is one of the most difficult cases at trial. Employment law in Japan is very protective of employees and a heavy burden is placed on employers to prove reasonable cause in all cases of dismissal. Therefore, an employer must prepare and collect detailed facts and evidence showing the employee is actually underperforming. The evidence should be objective, such as written warning letters, a written performance improvement plan, and emails with detailed facts expressing that the employee is underperforming.

Other laws (such as the LSA) set forth certain restrictions on dismissals, such as during maternity leave or medical treatment for a work-related injury.

If an employer wishes to dismiss an employee, the employer must provide at least 30 days' advance notice. An employer who does not give the 30-day notice is required to pay the average wage for no fewer than 30 days, except under certain conditions.30 An employer is not generally required to give notice to a works council or trade union when an employee is dismissed.

Based on its working rules, an employer may dismiss an employee because of a disciplinary action (punitive dismissal). In the case of a punitive dismissal, the courts will judge the validity of the dismissal pursuant to Articles 15 and 16 of the LCA.31

ii Redundancies

As with any dismissal, as discussed in Section XIII.i, the validity of a redundancy is judged by whether there are objectively reasonable grounds and whether it is considered appropriate in general societal terms. However, in general, redundancy will not become a reasonable cause for termination under case law in Japan, except in special circumstances, such as when an employer has no option other than redundancy to avoid going bankrupt.

Under case law, for redundancies to be deemed reasonable and appropriate, the following criteria must be met:

  1. Necessity: the business circumstances of the employer are in a situation that renders redundancies unavoidable and necessary.
  2. Efforts to avoid redundancy: in short, redundancies should be the measure of last resort.
  3. Reasonable selection: the standards for selection of employees who are subject to redundancy were reasonable and the redundancies were carried out fairly.
  4. Reasonable process: the employer conducted sufficient consultations with its employees and labour unions.

Transfer of business

i Merger

In a merger, employment contracts between a target company and its employees shall be automatically transferred to an acquiring company. Therefore, employees of the target company shall be employees of the acquiring company as of the effective date of the merger. Employees' working conditions remain the same at the acquiring company, so they are not materially disadvantaged. This is why there is no specific Japanese labour law to protect employees affected by a merger.

ii Asset transfer

In the event of a transfer of assets, each asset (including employment contracts) shall be transferred from a seller to a purchaser according to an asset purchase agreement. However, Japanese law requires employers to obtain consent from each employee to ensure the validity of the transfer of the employment contracts to the purchaser. The employees may decide whether they continue working for their current employer, so there is no specific Japanese labour law to protect employees affected by asset transfer.

iii Company split

In the event of a company split, a part or all of the company's assets and liabilities (including employment contracts) constituting a particular business of a seller shall be transferred from a seller to an acquirer based on a company split plan or agreement. While the Companies Act sets forth general procedures for the company to follow, the Labour Contract Succession Law regulates the transfer of employment contracts in a company split because of the consequences of a split on employees.


With the labour shortage arising from the declining birth rate and an ageing population, and the increasing burden of social insurance premiums, the expansion of employment of older people has been discussed. Currently, the Act on Stabilisation of Employment of Elderly Persons prohibits retirement before the age of 60. As a result, companies are obliged to take measures to secure employment opportunities up to the age of 65. In fact, even though there are already many workers who are over the age of 65 because of pension shortages or other reasons, the government is considering expanding the employment opportunities for older people up to the age of 70 as a growth strategy. It is anticipated that various approaches will be necessary. When considering these approaches, the needs and motivations of older people for various types of work and their state of health should be reviewed.

From 1 April 2020, the Act on Improvement, etc. of Employment Management for Part-Time Workers and Fixed-Term Workers and the WDA will be amended and enforced to improve the treatment of employees who do not work full-time. These amendments require that there be no unreasonable difference in treatment between regular employees and part-time and fixed-term workers, but there are often large differences in the content of duties and the range of changes in job assignments between regular employees and part-time and fixed-term workers. Therefore, it is thought that the disparity in basic salaries, and other differences, are unlikely to be recognised as unreasonable treatment.

With respect to dispatched workers, it is expected that their treatment will be improved by securing wages that exceed the average wage for similar jobs in the local area under the labour management agreement. This will affect a trend in the dispatched workers' market.

In addition, as stated in Section II, the Labour Policy General Promotion Act has been amended to impose on employers the duty to take measures to prevent power harassment. Many companies have already stipulated a prohibition of power harassment in their working rules, and have introduced a system to deal with violators by disciplinary measures. Therefore, the effects of this amendment are less significant. However, it should be noted that the perception of harassment beyond the framework of companies is becoming pervasive. It will be necessary to deal appropriately with instances of harassment when carried out by employees of other companies (e.g., an employee of one company is harassed or victimised by a business client hired by another company) or directed at employees of other companies (e.g., when the harassment is by an employee of one company against a business client hired by another company). Further preventive and reactive measures will be required in the future.
