Working late, never resting, and hiding weakness are not strength—they are evidence of incompetence.

Introduction: Is That "Strength" Really Strength?

In Japanese workplaces, not showing weakness, never resting, and working long hours have long been seen as virtues. Yet these are little more than endurance contests unrelated to outcomes, and they weaken the efficiency of the whole organization. True strength is the ability to deliver high-quality results quickly, contribute to sustained organizational growth, and do so within a team as well as individually.

Chapter 1: Misunderstood Strength and Its Limits

The "strength" traditionally praised in Japan looks like this:

  • Never showing weakness

  • Never relying on others

  • Working until collapse

But these attitudes do not increase efficiency or results. On the contrary, they cause health breakdowns and weaken teams.

Real strength is not about hiding weakness—it is about sharing it so the team can compensate and maximize performance.

Chapter 2: International Comparisons—Rest Does Not Reduce Results

OECD data tells the story clearly: France, Germany, and the Nordic countries work fewer hours, take all of their paid leave, and still outperform Japan in productivity per hour.

The U.S. has little statutory leave, but high incomes and widespread outsourcing (childcare, household help) offset this. Japan, by contrast, has generous legal provisions but cultural guilt about resting, which prevents people from taking leave and undermines productivity.

The evidence is clear: cultures that rest more often achieve higher productivity, not lower.

Chapter 3: The Roots of "Not Being Able to Rest"

  • United States: Limited legal protections, but compensated by income and services. High load, but rational.

  • Japan: Legal protections exist, but "air pressure" prevents their use. Results do not improve—irrational.

  • Europe: Rest is not just a right but a duty. Not resting is frowned upon.

Japan is thus trapped in the most irrational form of "not being able to rest."

Chapter 4: Redefining Strength as Productivity

Productivity can be broken down into operational efficiency and business efficiency.

  • Operational efficiency: The ability of individuals or teams to perform tasks without waste.

  • Business efficiency: The organizational ability to allocate resources effectively for maximum results.

Japan’s potential lies in adding customer satisfaction to this mix. Not in indulging customers at all costs, but in providing value-matched satisfaction through ingenuity, while cutting wasteful, excessive services.

This is the uniquely Japanese form of efficiency.

Chapter 5: How to Put It into Practice

Cultural change begins with systems and evaluation:

  • Mandatory leave: planned paid leave, managers visibly taking time off

  • Reward results, not hours: valuing employees who achieve more in less time; penalizing unnecessary overtime

  • Systems to support efficiency: automation, standardization, reducing dependency on individuals

  • Customer satisfaction with balance: ensuring efficiency while meeting expectations fairly

If institutions and evaluation change, culture will follow.

Chapter 6: Anticipating Objections

Critics say: "If we rest, we lose in competition," or "Shorter hours encourage cutting corners."
But:

  • Vacations can be covered by redundancy and teamwork.

  • Results can be evaluated with a balance of quality, quantity, and deadlines.

The problem is not resting itself, but the lack of systems designed around rest.

Chapter 7: Updating "Sanpō Yoshi"

The traditional Japanese business ethic of Sanpō Yoshi—good for the seller, the buyer, and society—can be updated for today:

  • Good for employees: healthier work-life balance, shorter hours with better results

  • Good for companies: higher efficiency and balanced customer satisfaction

  • Good for society: supports family life, childcare, and long-term employment sustainability

When strength is redefined as efficiency, results, and balanced customer satisfaction, Japan’s unique competitive edge emerges.

Conclusion: Replacing the Definition of Strength

For decades, Japan equated endurance with strength. Yet this has only reduced results and weakened organizations.

The strength of the future is sustainable productivity: efficiency and results, enriched with customer satisfaction. Rest must be treated not as a privilege but as a duty, and results must be measured not by time spent but by outcomes.

And the first step? Managers must take time off confidently and set the example.

Why Aren’t Wages Rising in Japan?

  Why Aren’t Wages Rising in Japan? — How the Labor Share Ratio and Retained Earnings Are Stalling Economic Growth Read the original article (in Japanese): 生産性3割アップも「増えない給料」　原因は「貯めこむ大企業」にあった | TBS NEWS DIG Chapter 1: The Illusion of Wage Growth Despite government announcements of a “historic wage increase,” most workers in Japan feel no real difference in their paychecks. The reality is that real wages have barely moved in 25 years , even though labor productivity has risen by roughly 30% during the same period. This growth rate exceeds that of major European economies like France and Germany. The popular narrative — “wages haven’t increased because productivity is low” — is no longer credible. The real question is this: Why are companies making more money, yet not paying workers more? Chapter 2: Record Corporate Profits, Yet No Pay Raises The most glaring figure is Japan’s retained earnings , also known as corporate savings or internal reserves. In 1998: approximately...

Proposing the Radical Idea of a “Tenure-Based Retirement System”

Read the original article (in Japanese): 「もう長すぎた…」宇宙飛行士・野口聡一氏が57歳でJAXAを辞めた納得のワケ( ダイヤモンド・オンライン ) The Reality Behind the 45-Year Retirement Debate The ongoing public debate around the “45-year retirement” and early retirement plans in Japan was initially intended to encourage self-directed career development. Yet, many workers interpret these initiatives as thinly veiled attempts to push them out. As astronaut Soichi Noguchi has noted, Japan’s work culture tends to reward compliance over skill-building or career ownership. If we want to change that, we need structural reform—not just slogans. The Proposal: A Tenure-Based Retirement System A better alternative is the Tenure-Based Retirement System . Rather than setting a fixed age for retirement, the idea is to define an employee’s career cycle within a company by tenure—say, a 20-year maximum. Such a system allows for natural career reflection without age-based discrimination. More importantly, it promotes a mindset where workers are exp...

How “Incompetent Seniors” Drive Young Employees Away Through Broken OJT Structures

On-the-Job Training (OJT) is originally meant to be a practical learning method where skills are honed through real work. Yet in practice, many companies abuse this term as a way to justify throwing new employees into unfamiliar tasks without guidance. This leads to frustration, underperformance, and ultimately, resignation. This article explores why such “OJT in name only” is problematic and what structural improvements companies must make—drawing comparisons to the foundational training methods found in sports and the arts. 1.
