“Japanese workers in the Showa era supposedly received bonuses worth 16 months of salary per year.”
At first glance, that sounds almost impossible.
If your monthly salary was 300,000 yen, a 16-month bonus would be 4.8 million yen.
If your monthly salary was 400,000 yen, the bonus alone would be 6.4 million yen.
From the perspective of today’s workers, that sounds like another world.
But the story is not completely baseless.
The short answer is this:
The claim that ordinary Showa-era workers received 16 months of bonuses alone is highly exaggerated.
However, if the claim means 12 months of regular salary plus around 5 months of bonuses, making total annual income equal to about 16 or 17 months of salary, then it becomes much more realistic.
And this connects directly to a famous Japanese TV commercial phrase:
“Can you fight 24 hours?”
This was the slogan of Regain, a Japanese energy drink.
It Was Not “Can You Work 24 Hours?” But “Can You Fight 24 Hours?”
First, the wording matters.
Many people remember the phrase as “Can you work 24 hours?” but the original Regain slogan was “Can you fight 24 hours?”
According to Regain’s official site, the first Regain product was launched in 1988. Its slogan was “Can you fight 24 hours?”, and its commercial song became a major hit. The phrase also won a bronze prize in the 1989 Buzzword Awards.^regain
So this was not exactly a symbol from the middle of the Showa era.
The product launched in 1988, the final year of Showa, and became a buzzword in 1989, the first year of Heisei.
It was more like a symbol of the late-Showa and early-Heisei salaryman culture.
It captured the moment when the Showa-style corporate worker operating system carried over into the Heisei era.
Was the 16-Month Bonus Real?
So, was the “16-month annual bonus” real?
Looking at the data, the idea that ordinary workers received 16 months of bonuses alone seems highly doubtful.
According to a paper in the Japanese Journal of Labour Studies, annual bonuses in manufacturing were around 1.7 months in the early postwar Showa period. They exceeded 2 months in 1956 and 3 months in 1961.^jil-bonus-early
In other words, ordinary postwar Showa workers were not suddenly receiving 16 months of bonuses.
However, the situation was different at large companies during the high-growth period.
The same paper explains that annual bonuses at large companies exceeded 5 months in 1965 and reached 6.1 months in 1970. In the Nikkeiren survey of companies with 500 or more employees, the figure was 5 months in 1965, 6.1 months in 1970, and 6.1 months again in 1973 and 1974.^jil-bonus-large
So, in large Showa-era companies, annual bonuses of 5 to 6 months were absolutely realistic.
From today’s perspective, that is already very strong.
But the number is 5 or 6 months, not 16 months.
The “16-Month” Story Probably Comes From “17 Months of Annual Wages”
So where did the “16 months” story come from?
The likely source is the idea of “17 months of annual wages.”
The same Japanese Journal of Labour Studies paper explains that the electric industry labor federation treated bonuses as part of annual wage income and aimed for at least 5 months of bonuses. This followed the idea of 17 months of annual wages stated in its 1978 wage policy.^jil-17months
That means:
12 months of regular salary + 5 months of bonuses = 17 months of annual income
In other words, it was not a 17-month bonus.
It meant that total annual income, when converted into monthly salary units, equaled 17 months.
Once this gets passed around casually, it can easily become distorted:
“Annual income equals 17 months of salary”
↓
“Salary including bonus is 17 months”
↓
“The bonus is 17 months”
↓
“Showa workers got 16 months of bonuses”
So the accurate version is this:
A 16-month bonus alone is exaggerated.
But annual income equal to 16 or 17 months of salary, including bonuses, really did exist in some companies.
Did 16-Month-Level Bonuses Never Exist?
There is one nuance.
The claim that ordinary Showa-era salarymen received 16 months of bonuses is highly doubtful.
However, if we include older periods and specific employee classes, there were examples of very large bonuses.
The same paper introduces a case from Oji Paper in the Taisho era: section-chief and factory-manager-level employees received annual bonuses worth 20 to 24 months; assistant-manager-level employees received 10 to 20 months; regular white-collar employees received 8 to 10 months; while factory workers received around 2 months.^jil-taisho
So it is not true that “16-month-level bonuses never existed anywhere.”
But that was not the story of the average Showa-era worker. It was closer to the world of prewar or Taisho-era white-collar and managerial employees.
If this distinction is ignored, the story becomes distorted.
Old high-bonus episodes.
Large-company 5-to-6-month bonuses during the high-growth era.
The electric industry’s 17-month annual wage model.
Regain’s “Can you fight 24 hours?” slogan.
When all of these are mixed together, the internet turns it into a rough claim like:
“Showa workers got 16-month bonuses.”
That Is Why “Can You Fight 24 Hours?” Worked
The important point is that the old Japanese corporate culture was not just pure willpower ideology.
Today, “Can you fight 24 hours?” sounds almost like a black-company slogan.
But at the time, there was a kind of exchange behind it.
You entered a large company.
You stayed there for a long time.
You devoted yourself to the company.
You worked overtime.
You accepted transfers.
You built your life around the company.
In exchange:
Bonuses were large.
Wages rose over time.
Employment was stable.
You could support a family.
You could take out a housing loan.
The company functioned as part of your life infrastructure.
That was the package.
In other words, the old corporate worker operating system was:
“You entrust your life to the company, and the company also supports your life.”
From today’s perspective, that sounds extremely heavy.
But for many people at the time, it was not just meaningless overwork. It was also a path to stability, upward mobility, and family security.
But They Really Were Working Too Much
Of course, this should not be romanticized too much.
The long working hours were genuinely harsh.
A paper in the Japanese Journal of Labour Studies discussing long working hours refers to the popular 1988–1990 commercial phrase “Can you fight 24 hours, Japanese businessman.” It also explains that from 1986 to 2006, male full-time workers’ weekly working hours remained around 50 to 54 hours across company sizes for nearly 20 years.^jil-long-hours
Even as the five-day workweek spread, weekday working hours became longer. The paper also points to reduced sleep, chronic fatigue, and increased overwork risks.^jil-long-hours
So “Can you fight 24 hours?” was not just a joke.
People really were fighting quite a lot.
The difference from today is that the old system still had stronger returns: bonuses, raises, employment security, and a corporate community.
When the Old System Remains Today, It Becomes Hell
The real problem is when the Showa-style worker operating system survives only halfway in the modern world.
The old system looked like this:
High workload
High commitment
High bonuses
Wage growth
Employment stability
The company supports your life
But today, the reward side is often weakened.
What remains is:
High workload
High commitment
Low wage growth
Unstable bonuses
Unstable employment
Personal responsibility for everything
At that point, it is no longer a fair exchange.
It becomes exploitation.
So the issue is not simply “Showa was better.”
The real issue is companies that keep the Showa-era burden but no longer provide the Showa-era return.
If a company wants to ask, “Can you fight 24 hours?”, then it should also provide 5 to 6 months of bonuses, wage growth, employment stability, clear responsibility boundaries, real authority, and life security.
If it only demands toughness without paying the price, that is not Showa culture.
That is just a black company.
Conclusion
The claim that “Showa workers received 16 months of bonuses per year” is exaggerated as a general statement.
According to the available data, annual bonuses at large companies reached the 5-to-6-month range in the 1960s and 1970s, but a 16-month bonus alone was not the general reality.
However, if the claim means 12 months of salary plus 5 months of bonuses, making annual income equal to 17 months of salary, then it becomes quite realistic for large companies in industries such as electronics, automobiles, and steel.
And that salary structure helped support the culture behind “Can you fight 24 hours?”
So the essence of the story is not:
“Showa workers got 16 months of bonuses.”
The essence is:
In late Showa and early Heisei Japan, long working hours, loyalty to the company, high bonuses, wage growth, and employment security were bundled together into one corporate worker operating system.
Today, the question should not be “Was the past better?”
The question should be:
Is this company demanding the Showa-era burden while refusing to pay the Showa-era return?
“Can you fight 24 hours?”
A modern worker’s answer should probably be:
If compensation, authority, responsibility boundaries, and employment stability are included, I’ll consider it.
If it is just willpower, then no.
