Zangyo is an unavoidable theme when discussing Japanese work styles. It is not just about extra working hours but also reflects history, culture, and social values, making it a focus of international attention.

The Basic Definition of Zangyo

In Japan, zangyo means working beyond the legally established working hours under the Labor Standards Act. By law, the standard is 8 hours per day, 40 hours per week. Anything beyond that is considered overtime, and companies must sign a “36 Agreement” with employees to allow it.

Zangyo is classified into four main categories:

CategoryDescriptionExtra Pay Rate
Within Legal LimitBeyond company rules but within legal hoursRegular wage
Beyond Legal LimitExceeding the legal standard25% or more
Night WorkFrom 10 PM to 5 AM25% or more
Holiday WorkOn statutory holidays35% or more

Although the rules appear clear, in practice, issues such as unpaid zangyo and vague labor management often arise.


Cultural Background of Zangyo in Japan

The persistence of zangyo in Japan can be traced back to the postwar high economic growth period. At that time, the belief that “the more you work, the richer the country becomes” spread throughout society. As a result, long working hours were praised as proof of one’s contribution to the company.

In addition, traditional employment practices such as lifetime employment and seniority-based promotion encouraged more overtime. Workers often avoided leaving before their boss or stayed late to support colleagues, creating strong pressure to engage in zangyo.

Thus, overtime became more than just extended hours. It was treated as a symbol of loyalty and responsibility.


Modern Japan and the Zangyo Problem

Excessive working hours developed into a serious social issue. The word karoshi (death from overwork) became internationally known, symbolizing Japan’s challenges.

In response, the government introduced the Work Style Reform policy, placing limits on zangyo. In principle, 45 hours per month and 360 hours per year are the maximum. Even during busy periods, the annual limit is 720 hours.

Yet problems persist. Unpaid zangyo, hidden overtime during remote work, and conflicts between performance-based evaluation and time reduction remain unresolved. Therefore, it is not enough to simply regulate time—companies must also improve efficiency and review evaluation systems.


Zangyo in International Comparison

Japan does not necessarily have the longest working hours in the world. However, the way time is used is distinctive. Lengthy meetings and coordination tasks reduce efficiency, which in turn leads to zangyo.

The table below compares working hours and productivity in major countries:

CountryAnnual Avg. Working HoursProductivity (GDP per hour)Characteristics
Japan~1600MediumHours decreasing, but efficiency is low
Germany~1350HighFocus on efficiency and leaving on time
South Korea~1900LowChronic long working hours
Netherlands~1400HighStrong emphasis on work-life balance

This comparison shows that Japan’s main issue is not just the length of work but low efficiency.


Actual Zangyo by Industry

The situation of zangyo varies greatly across industries.

IndustryFeaturesReasons for Zangyo
ManufacturingPeaks during busy seasonsProduction schedules
ITChronic long hoursLabor shortage, strict deadlines
ServiceIrregular shiftsCustomer demand and flexibility
Foreign firmsRelatively little overtimePerformance-based, efficiency-oriented

Thus, both industry characteristics and company culture strongly affect whether zangyo occurs.


Efforts to Reduce Zangyo

Both the government and companies are implementing measures to reduce zangyo.

InitiativeDescriptionExpected Effect
FlextimeFlexible start and end timesBetter work-life balance
Remote workWork from homeShorter commutes, higher efficiency
No Zangyo DayMandatory early leaveCorrecting long-hour culture
AI utilizationAutomating tasksImproved efficiency

These efforts are not just about reducing hours but about improving the quality of work styles.


How Foreigners See Japanese Zangyo

Foreign workers and researchers often express surprise at Japan’s time-based evaluation rather than results-based evaluation. For many outside Japan, working longer hours is not considered proof of dedication.

At the same time, Japan’s strong sense of responsibility and teamwork can leave a positive impression. However, in an increasingly globalized world, Japan needs to shift toward efficient and flexible work styles to remain competitive.


The Future of Zangyo and Japanese Society

Due to an aging and shrinking population, Japan cannot sustain a work system dependent on zangyo. Younger generations now value work-life balance more than previous ones and tend to reject excessive overtime.

With advancing technology and shifting values, zangyo is expected to decrease. In the future, overtime may become an exception rather than the norm.


Conclusion

Zangyo has been deeply rooted in Japanese society. It has long been seen as a symbol of diligence, but at the same time criticized as a symbol of inefficiency. While legal regulations and corporate reforms are progressing, cultural and habitual influences remain strong.

Japan’s challenge is to move away from treating zangyo as a virtue. Building a work culture that values efficiency and allows people to live healthy and fulfilling lives will be key to shaping the future of Japanese society.
