Semantically similar decisions — same territory, different trade-offs.
En Japan’s March 2023 survey of 12,940 Japanese workers found that 45% of those who had
never changed jobs wished in retrospect that they had changed employers earlier, citing
broader experience, higher compensation, and greater personal development as the gains they
missed. On the opposite side, 26% of those who had changed jobs reported the transition
was harder than expected or that they missed aspects of their former employer — accumulated
seniority, pension accrual, team relationships, and the social identity attached to a
well-recognised company name. The Japan Institute for Labour Policy and Training (JILPT) 2022
analysis corroborates the directional finding: workers who changed jobs mid-career earned
approximately 15-20% more than comparable lifetime employees by age 45, providing a material
basis for retrospective regret among those who stayed.
The finding is action-dominates — an unusual configuration in the regret literature, where
Gilovich and Medvec’s temporal model predicts that inaction regret should dominate over long
horizons. Japan’s institutional context explains the reversal. The seniority wage system
(nenko joretsu) delivers compensation gains primarily in the final decade before retirement;
workers who evaluate their mid-career trajectory see a wage deficit relative to job-changers
without yet having received the back-loaded benefits. The cultural shift among younger cohorts
is also structural: Japan’s share of non-regular workers rose from 15% in 1984 to approximately
37% in 2023, eroding the tenure guarantee that made lifetime employment a rational choice in
the first place. JILPT data notes that many early job-changers re-enter organisations with
similar hierarchical and seniority-based cultures, limiting the diversification benefit and
contributing to the 26% post-change regret rate.
The principal caveat is sponsor bias: both regret rates derive from a survey conducted by En
Japan, a job-change platform with a commercial interest in promoting mobility. The 45% figure
may overstate lifetime-employment regret because the survey population was drawn from a
platform used by workers actively considering or having already completed a job change — a
sample selected for dissatisfaction with the status quo. The retrospective assessment also
arrives before the full pension and seniority benefits of a long career have accrued, so
workers may be evaluating an incomplete outcome. The directional finding (action-dominates)
should be interpreted as Japan-specific rather than universal.

Calculation
En Japan surveyed 12,940 active and past job-change platform users. Among the subset who had never changed jobs, 45% expressed retrospective regret about not having done so. This is used directly as the action-side regret rate (regret staying on the lifetime-employment track). Sponsor bias is a material caveat: En Japan operates a job-change platform and has a commercial interest in framing lifetime employment negatively. NOTE: The primary URL (corp.en-japan.com/newsrelease/2023/31734.html) returns 404 as of 2026-05-14; the n=12,940 and 84%-overtime figures are confirmed by Nippon.com secondary coverage. The 45% and 26% bilateral regret rates could not be independently verified from a live primary source. proxy_only: true set accordingly.

Government report
Workers who changed jobs mid-career earn approximately 15-20% more than lifetime employees by age 45 under seniority-wage benchmarking
Excerpt
“[Paraphrase from abstract — full text paywalled] JILPT's 2022 analysis of Japanese wage structures found that mid-career job-changers who successfully transition to external employers earn approximately 15-20% more than comparable lifetime employees by age 45, primarily because the seniority (nenko joretsu) system front-loads wage growth toward retirement and disadvantages workers who would benefit from market wage discovery earlier in their careers.

The JILPT wage-premium data corroborates the En Japan regret rate by providing a material basis for retrospective regret: workers who stayed on the lifetime-employment track objectively earned less through mid-career than those who changed jobs. This source does not provide a direct regret rate; it supports the plausibility and direction of the 45% figure.

From the same En Japan survey (n=12,940). Among job-changers, 26% reported post-change regret. Used directly as the inaction-side regret rate (regret having changed jobs rather than staying). Both sides derive from the same survey instrument, which minimises measurement inconsistency but amplifies any sponsor bias present in the source.

Early-career job change rates rose to 19% for high school graduates and 8% for college graduates within 1 year; many re-enter similar organisational cultures
Excerpt
“[Paraphrase from abstract — full text paywalled] JILPT's 2022 analysis notes that early-career job change rates among high school graduates within one year of employment reached approximately 19%, while the rate for college graduates was approximately 8%. A significant proportion of early job-changers re-enter organisations with similar hierarchical and seniority-based cultures, which limits the material benefit of changing and contributes to post-change disappointment.

Calculation
JILPT data on re-entry into similar cultures supports the plausibility of the 26% inaction-side regret rate by explaining a mechanism: job-changers who exit into comparable environments do not obtain the diversification benefit they anticipated. This source does not provide a direct regret rate.
Caveats
Both regret rates derive from the same En Japan survey, conducted by a job-change platform that has a strong commercial interest in promoting job mobility. The 45% "wish I had changed earlier" figure is retrospective self-report from workers who remained on the lifetime- employment track; at the time of survey these workers may not yet have received the full pension and seniority benefits that accrue late in a Japanese career, making the assessment premature. The Japanese labour market is undergoing structural change: the share of non-regular workers has grown from 15% in 1984 to approximately 37% in 2023, meaning the traditional lifetime-employment premium (guaranteed tenure, pension, status) is available to a shrinking fraction of the workforce. For workers who never had access to genuine lifetime employment, this entry's framing is not applicable. The JILPT corroboration sources provide material context but do not supply independent regret rates. The regret asymmetry (action-dominates, meaning regret from staying exceeds regret from leaving) is unusual in the global regret literature, where inaction-dominates is the modal pattern over long horizons; it likely reflects Japan-specific institutional dynamics rather than a universal finding.
