The work time system is one of the most important aspects of human resources and labor management for businesses. It is not only a key element in labor law compliance, but also an essential tool in building a compensation structure. In fact, Japan’s work time system is similar to that of many countries, offering various options. A deep understanding of Japan’s work time system, when applied correctly under the premise of legal compliance, can greatly enhance the satisfaction of both employers and employees, achieving a win-win situation for both sides.

Overview of Japan’s Work Time System
Japan’s work time system can be divided into two main types: the standard work time system and the special work time system.
The standard work time system, also known as the statutory work time system, is defined by Article 32 of Japan’s Labor Standards Act, which stipulates that employees work 8 hours a day and 40 hours a week, excluding break times. Under this system, any work beyond the statutory work hours is considered overtime, for which employers must pay overtime wages. This system is simple and straightforward, making it easier for businesses with stable operational rhythms to manage human resources.
However, many businesses experience fluctuations in their operations due to seasonal changes, busy and slow periods, or job characteristics that extend beyond the applicability of the standard work time system. To address this, special work time systems have been introduced, which include more flexible systems such as modified work hours and systems that treat certain work time as deemed working hours. The following sections introduce these special work time systems in Japan’s labor law.
Special Work Time Systems in Japan
Japan’s special work time systems can be roughly classified into three categories:
- Modified work hour systems, including work hours modified within a specific period, and flexible work hour systems.
- Deemed work hours, including work time deemed outside the workplace, discretionary work systems (for specialized and planning types of discretionary work), and
- High-level expert work hour systems.
1. Modified Work Hour Systems
These systems allow businesses to adjust work hours according to busy and slack periods within a given timeframe, ensuring that the overall work hours during that period comply with statutory requirements. Specific periods can be broken down into weekly, monthly, or yearly modified work hour systems, as well as flexible work hour systems. Due to the limited scope of application for weekly modified work hours, the following explanation primarily focuses on the monthly and yearly modified work hour systems and flexible work hour systems.
According to the Ministry of Health, Labor, and Welfare’s 2023 Employment Status Report, 64% of Japanese companies use modified work hour systems, with the yearly modified work hour system being the most popular, accounting for 34.3% of such companies. At the same time, the Japanese government is actively promoting flexible work time systems.
(1) Yearly Modified Work Hour System
In the yearly modified work hour system, the statutory upper limit on work hours during busy periods can be adjusted: the daily work hour limit is 10 hours, and the weekly work hour limit is 52 hours. During this modified period, employees can work up to 6 consecutive days. The 6-day limit can be extended to 12 days if consecutive rest days are placed at the start and end of the period. Additionally, for periods exceeding 3 months, the law stipulates that the total number of workdays in the year cannot exceed 280, and continuous work weeks exceeding 48 hours can only last for 3 weeks.
(2) Monthly Modified Work Hour System
For periods within one month, businesses may implement modified work hours due to short-term busy or slack periods. During this period, the average weekly work hours must not exceed statutory limits (40 hours per week, or 44 hours for special cases). Additionally, at least one rest day must be ensured each week, or four rest days within a four-week period.
(3) Flexible Work Hour System
The flexible work hour system allows businesses to set total work hours within a 3-month period, with employees deciding their own attendance times. Typically, core working hours are designated to ensure normal operations while employees are present. Within this system, weekly average work hours must not exceed 40 hours, or 44 hours for special cases.
2. Deemed Work Hour Systems
Deemed work hour systems include work time deemed outside the workplace and discretionary work systems (for specialized and planning types of work). The work time deemed outside the workplace system applies when work is done outside the office, and it is difficult to calculate working hours, so work time is generally recognized based on the designated work time.
Discretionary labor systems apply to jobs where the nature of the work requires employees to make independent decisions about their work, such as planning, analysis, and research. This system is defined through a labor agreement or a labor committee decision, and employees must give written consent to apply this system.
(1) Definitions and Scope
The planning-type discretionary labor system applies to work related to business planning, design, and analysis. It provides employees with a significant amount of autonomy over their work, allowing them to exercise considerable discretion. This system is implemented after a decision by the labor committee and a report to the Labor Standards Supervision Office. The specialized business discretionary labor system applies to positions requiring specialized knowledge, where it is difficult to provide specific instructions on work methods and hours. In these cases, the work is considered to have been done within the working hours agreed upon in the labor agreement.
3. High-Level Expert Work Hour System
This system is targeted at high-income professionals, specifically those with annual incomes of 10.75 million yen or more. Under this system, the statutory work hours, rest periods, and overtime rules are generally not applicable. However, employees under this system must be guaranteed 104 rest days per year and 4 rest days every 4 weeks. Written consent from the employee is also required.
Conclusion
This article has provided a brief overview of Japan’s special work hour systems. Similar to China’s special work time systems (such as the comprehensive calculation work hour system and the irregular work hour system), Japan’s special work time systems respond both to the objective needs of business operations and to the particularities of certain job types. By understanding and correctly applying these systems, foreign-owned companies operating in Japan can more effectively manage human resources, improve cost control, and enhance efficiency, ultimately achieving a win-win situation for both employers and employees.
