Quit Your Job or Keep It Forever: A Field Guide to Career Loyalty in America and Japan

🇺🇸 USA · 🇯🇵 Japan

By Priya Mehta, The Global Office

An American worker changes employers roughly every 3.9 years, according to the Bureau of Labor Statistics, treating a resignation letter as a mundane administrative document. A Japanese worker, by contrast, stays with a single employer for a median of just over 12 years, per Japan Institute for Labour Policy and Training figures — long enough, in American terms, to outlast several rounds of "restructuring," two CEOs, and one entire product line. Neither country is transitioning to the other's model quickly, but both are drifting, awkwardly, toward the middle, and the person relocating for work is the one left explaining to a new employer why their résumé looks the way it does.

The United States: Loyalty Is a Liability

American labor markets are built for motion. The BLS's January 2024 data put median tenure at 3.9 years overall — 3.5 years in the private sector — the lowest figure since the series began in 2002, and workers aged 25 to 34 stay barely 2.7 years on average. Employers have adjusted accordingly: internal promotion cycles are slow, external hiring is fast, and the surest way to a meaningful raise is frequently to leave. Loyalty, in this system, is not rewarded so much as quietly priced against you — the employee who stays five years often earns less than the one who left twice.

This creates a workplace where career mobility is the default operating assumption, not an act of defiance. Managers plan for attrition. Recruiters treat a stagnant LinkedIn profile as more suspicious than a busy one. The tradeoff is instability: no employer owes you a decade, and none expects to be owed one either.

Japan: The Slow Erosion of a Promise

Japan's postwar model of shūshin koyō — lifetime employment in exchange for unwavering loyalty — is still the cultural reference point even as its practice narrows. A Recruit Works Institute survey cited by Nippon.com found only 30.1% of workers now say they want to stay at one company through retirement, a marked decline from the model's mid-century dominance. Meanwhile, the World Economic Forum reports that by 2026, non-permanent workers are projected to exceed 40% of Japan's total workforce, and the Japanese government has begun funding mid-career reskilling leave to help workers who lack employer-sponsored training make the jump.

Yet the infrastructure of loyalty persists longer than the sentiment. Seniority-linked pay scales, internal-only promotion tracks, and the social weight of tenshoku (changing jobs) as a notable life event have not disappeared just because fewer workers believe in them. A new arrival will find a system in the middle of an identity crisis: young employees increasingly want mobility, but the scaffolding around them — pay bands, promotion timing, even office seating charts by hire year — was built for people who were never supposed to leave.

The Reckoning

The irony is that both countries are converging on distrust of their own systems for opposite reasons. Americans increasingly complain that job-hopping, now mandatory for a decent raise, has become exhausting rather than empowering — a treadmill dressed up as freedom. Japanese workers, meanwhile, are discovering that mobility, once available, doesn't automatically translate into leverage: without an established norm of competitive counteroffers, changing jobs in Japan can mean starting over at the bottom of a new seniority ladder rather than negotiating up.

Hofstede Insights scores the US at 91 on individualism against Japan's 46, and that gap explains more than it seems to. In the US, career mobility is read as an individual optimizing their own trajectory — an unremarkable, even admirable, act. In Japan, the same move is read against the group: what does leaving say about the team you're abandoning? An American manager transplanted to Tokyo who praises an employee's ambition to leave in two years will find the compliment lands very differently than intended.

The Part the Brochure Left Out

r/japanlife — One American software engineer described the "gaijin trap": after two years teaching English then moving into a tech role, they found interviewers kept steering conversations back to the teaching gap, treating it as a red flag regardless of the skills gained since.

Quora — A respondent who spent a decade as a salaryman wrote that the biggest misconception outsiders bring is mistaking seniority-based promotion for a lack of opportunity — it's slower, he said, but the ceiling is higher than people assume once you clear the first eight years.

teamblind.com — A senior engineer who rotated through offers at Google Japan, Amazon Japan, Woven by Toyota, and Microsoft Japan concluded the math only works above the senior level; below that, compensation and hours didn't justify the move, and they eventually returned to a US employer.

Internations Tokyo — A British project manager noted that InterNations events ended up doing more for her career transition than any job board, since Japanese recruiting channels aren't built around expat networks the way European ones are.

r/cscareerquestions — One transplant admitted the pleasant surprise was job security: after two rounds of layoffs at a previous US employer, they described the near-total absence of at-will termination anxiety in their Japanese contract as "the first time in years I stopped checking Slack on Sunday night."

Conclusion

The practical question for anyone relocating is not which system is better, but which risk you're better suited to carry. Move to the US and you're trading security for optionality — a career that moves fast but owes you nothing. Move to Japan and you're trading optionality for a slower, steadier climb that still, in most industries, rewards patience over hustle, even as that reward shrinks. Neither trade is free. If a friend asked me over drinks, I'd tell her: figure out whether you're the kind of person who finds security boring or exhausting, because that answer, more than any spreadsheet of tenure statistics, is what will actually determine whether you thrive.
