Employment Law Overview Japan


Japanese employment laws mainly cover employer-employee relationships. These laws apply to all employees working in Japan regardless of their nationality. However, board members as defined under the Company Act (2005) as well as independent contractors are not categorised as employees subject to Japanese employment laws, in principle, and therefore are not protected under Japanese employment laws.

Key Points

  • Japanese employment laws mainly cover employer-employee relationships. Board members and independent contractors are, in principle, not categorised as employees.
  • There is no “at will” employment in Japan. Japanese law requires that termination of regular employment shall be considered objectively, deemed reasonable, and appropriate upon social convention, which is read rigidly in light of Japanese judicial precedent.
  • Regulation concerning overtime work has been strengthened with the recent legislative amendments. In principle, work on statutory public holidays and late-night work requires extra allowance in addition to the normal wage.
  • Japanese law provides various protections against discriminative treatments not only by reason of nationality, creed, social status or gender, but also due to the association with union activities, or taking child care or nursing care leave. There is also a prohibition against unreasonable differences between full-time permanent employees and non-regular employees. Furthermore, an employer’s obligation to prevent harassment has been strengthened in light of the recent legislative amendments.
  • Dominant majority unions in Japan are deemed as enterprise unions. The unionisation rate in Japan has been considerably and continuously declining.

Employment law in Japan is predominantly based upon the following sources:

  • the Constitution (1946);
  • laws, in particular, compulsory laws including but not limited to the Labour Standards Act (1947), the Labour Contract Act (2007), the Minimum Wage Act (1959), the Industrial Safety and Health Act (1972), the Industrial Accident Compensation Insurance Act (1947), the Act on Securing, etc. of Equal Opportunity and Treatment between Men and Women in Employment (1972) (the “Equal Opportunity Act”), the Act on the Welfare of Workers Who Take Care of Children or Other Family Members Including Child Care and Family Care Leave (1991) (the “Child Care and Nursing Care Act”), the Act on Improvement of Personnel Management and Conversion of Employment Status for Part-Time Workers and Fixed-Term Workers (1993) (the “Part-Time/Fixed-Term Employment Act”), the Labour Union Act (1945), the Employment Security Act (1947) and the Act for Securing the Proper Operation of Worker Dispatching Undertakings and Improved Working Conditions for Dispatched Workers (1985) (the “Worker Dispatch Act”);
  • government ordinances and implementation regulations;
  • collective bargaining agreements;
  • company’s work rules; and
  • employment contracts.

Furthermore, administrative authorities have published various guidelines relating to labour laws. The purpose of these guidelines is to assist in the legal interpretation of the applicable laws. These guidelines are not legally binding, however, they are widely accepted as the social standard and/or best practices in Japan. In particular, Supreme Court precedent has the potential to have considerable influence on the application of labour and employment laws in market practice and Japanese custom.

New Developments

One of the most significant legislative changes impacting the operations of employers in Japan is due to the recent overhaul of employment legislation, following the enactment of the Work Style Reform Act (the “Reform Act”). The Reform Act has had a substantial impact on employees due to the following notable changes: (i) amendments to the working hours system; (ii) ensuring the use of annual paid leave; (iii) tracking of working hours; and (iv) “equal work, equal pay”.

As to (i) working hours system, the Labour Standards Act provides a limitation on the number of overtime hours of employees as a general rule (e.g. not more than 45 hours per month and 360 hours per year). However, prior to the Reform Act, employers were, in exceptional circumstances, allowed to request employees to work overtime in excess of these limits if “special circumstances” existed (e.g. during busy periods). The Reform Act amended the relevant provisions of the Labour Standards Act, and modified this practice significantly by introducing a legal cap on the total number of overtime hours employees are permitted to work. These amendments came into effect in April 2019.

As to (ii) annual paid leave, in practice, it has been common in Japan for employees to not utilise the majority of their annual paid leave. Furthermore, employees frequently allow their annual paid leave to lapse. The Reform Act amended the relevant provisions of the Labour Standards Act, and has introduced an obligation on employers to ensure that their employees utilise at least 5 days of annual paid leave per year (or during a period that can be designated by the employer). These amendments came into effect in April 2019.


As to (iii) tracking of working hours, the Reform Act amended the Industrial Safety and Health Act and introduced a new legal obligation on employers to accurately track their employees’ working hours by utilising methods indicated in the ministry ordinance. These methods include implementing the ‘clock-in/clock-out’ method of recording time via employees’ ID cards and/or recording the time employees log in and out of their work computers. These changes have been introduced in an effort to curb excessive working hours as well as to assist employers in monitoring the health of their employees. The amended guidelines have provided greater clarity for employers regarding the methods they should use to monitor the working hours of their employees. These amendments came into effect in April 2019

As to (iv) “equal work, equal pay”, the Reform Act amended the Part-Time/Fixed-Term Employment Act, and has introduced the requirement for workers to receive fair and equal treatment irrespective of their job status. Furthermore, the Reform Act prohibits irrational disparity between ‘regular’ and ‘non-regular’ employees. These amendments have resulted in a requirement for reasonable equal treatment of regular employees (i.e. full-time permanent employees) and non-regular employees (which includes fixed-term contract employees, part-time employees, and dispatch employees). These amendments came into effect in April 2020.

Another noteworthy legislative change pertains to the amendments of the Equal Opportunity Act and the Act on Comprehensive Promotion of Labour Policies (1966), both of which came into effect in June 2020. The amendments require employers to introduce measures to prevent harassment by establishing a consultation system, and prohibit the dismissal or mistreatment of workers who consult or cooperate with a harassment-related investigation.

Another major legislative change pertains to the amendments on the Act on Stabilisation of Employment of Elderly Persons (1971), which are due to come into effect in April 2021. Under the amendments, an employer whose employees have reached the age of 65, shall endeavor to apply one of the following measures to such employees until they reach the age of 70: (a) a raise of retirement age; (b) introduction of a continuous employment system; (c) abolition of retirement age; or (d) measures other than employment by executing the labour-management agreement (specifically, a system for continuous outsourcing contracts or a system allowing for employees to engage in social contribution activities on a continuous basis). It is important to note that this is only an obligation for employers to make such efforts and is not a mandatory obligation. There are no sanctions imposed on employers for not implementing any of the measures, (a)-(d), as outlined above.
