The previous essay, “The Male-Line Succession Myth,” found that in the discourse surrounding family succession, bloodline, wisdom, and institutions are all interchangeable tools \u2014 the one constant that never moves is sex. This essay examines how the very same structure is reproduced, almost exactly, in a seemingly unrelated domain: contemporary Japanese business and politics.<\/p>\n\n\n\n
It has been forty years since the Equal Employment Opportunity Act took effect. Formal equality of opportunity has, at least on paper, been achieved. And yet the share of women among managers, among members of the Diet, and among executives of listed companies in Japan remains strikingly low by international standards.<\/p>\n\n\n\n
According to Japan’s Ministry of Health, Labour and Welfare’s FY2024 Basic Survey on Gender Equality in Employment Management, women hold only 13.1% of positions at section-manager level or above. The higher the rank, the lower the figure falls \u2014 dropping to 8.7% at department-manager level. The Cabinet Office’s White Paper on Gender Equality shows that women make up roughly 16% of those in “managerial occupations” in Japan, compared with 30% or more in most other advanced economies. Politics fares even worse: following the 2024 general election, women held 15.7% of Lower House seats \u2014 last among the G7 \u2014 and Japan sits in the 140s out of 185 countries in the Inter-Parliamentary Union’s international rankings. Among corporate boards, the share of women on the boards of Tokyo Stock Exchange Prime Market companies had only reached the 18% range by 2025, well short of the government’s 30% target for 2030.<\/p>\n\n\n\n
These figures are not simply a story of “slow progress.” Women make up 44\u201345% of the overall workforce \u2014 a share comparable to other advanced economies \u2014 yet vanish sharply and specifically once one moves into decision-making tiers. This is a distinctive fault line, not a gradual lag. This essay examines three forces producing that fault line, in turn: baseless assumptions, institutional inaction, and delayed countermeasures.<\/p>\n\n\n\n
The idea that “women will eventually quit or take leave for childbirth and childcare, so investing in their development as managers won’t pay off” remains stubbornly common on the ground in Japanese corporate HR departments. This is a textbook case of what economists call “statistical discrimination”: deciding an individual’s treatment based purely on a probabilistic attribute assigned to a group (a possibly higher attrition rate), without regard to that individual’s own motivation or ability.<\/p>\n\n\n\n
This reasoning is flawed in two distinct ways.<\/p>\n\n\n\n
First, the underlying premise \u2014 “women quit easily” \u2014 is itself a result<\/em>, not a cause. It is entirely unsurprising that people denied development investment, denied responsible assignments, and sidelined from the promotion track lose motivation and eventually leave. This is not “quitting because they’re women” but “quitting because they were treated this way” \u2014 a reversal of cause and effect. The sequence runs: first, an operational practice (sidelining employees into dead-end roles after parental leave, automatically removing reduced-hours workers from the promotion track); then, as its consequence, “data” showing higher attrition or lower promotion motivation is generated after the fact; and that data is then cited as the basis for the very judgment (“so we can’t invest in women”) that produced it in the first place. This is a classic self-fulfilling prophecy, in which cause and effect are inverted while being presented as if they were objective statistics.<\/p>\n\n\n\n Second, the evaluation criteria for managerial aptitude \u2014 “leadership,” “decisiveness,” “resilience” \u2014 are themselves often unconsciously designed around patterns of behavior coded as masculine. Numerous empirical studies, in Japan and abroad, confirm an evaluation bias in which collaborative decision-making or empathetic communication, even when equally effective, is read as “lacking leadership,” while the very same strong assertiveness is read as “reliable” in a man and “difficult to work with” in a woman. In other words, the evaluation standard itself, while claiming neutrality, is quite likely designed in a way that favors one sex.<\/p>\n\n\n\n Having examined both of these “grounds,” one conclusion needs to be stated plainly. Neither the phenomenon of “women quit easily” nor the judgment “lacks leadership” is an inherent defect of women as a category. It is organizations themselves that designed, operated, and left unchanged for decades the personnel practices that sideline employees after parental leave, automatically remove reduced-hours workers from the promotion track, and misread empathetic communication as a deficit in a formal evaluation system. The failure \u2014 or refusal \u2014 to implement measures that would prevent attrition and make full use of talent (support for balancing work and childcare, fair evaluation design, mechanisms for continuous career development) is a dysfunction on the part of the organization: institutional inaction, or, put bluntly, incompetence in management and HR. Shifting this cause onto “a tendency among women” merely disguises where the problem actually lies. The undeniable cause is the organization’s own failure to act.<\/p>\n\n\n\n All of this mirrors precisely the structure examined in the family-succession essay. The conclusion \u2014 “women aren’t suited to management” \u2014 comes first; the “reasons” offered to support it (attrition rates, a supposed lack of leadership) are, in fact, the results of institutional practice, rearranged after the fact to look like causes.<\/p>\n\n\n\n The main reason equal-opportunity law has not translated into equal outcomes is that the preconditions needed to actually exercise that opportunity have \u2014 whether by intent or by consequence \u2014 been left untouched for a very long time.<\/p>\n\n\n\n The Long-Hours Barrier to Entry<\/strong><\/p>\n\n\n\n The promotion track to management in Japanese companies still frequently treats “capacity to endure long working hours” as an implicit qualifying condition. Given that unpaid care labor \u2014 childcare and eldercare \u2014 falls disproportionately on women (the so-called “second shift”), this “tolerance for long hours” standard is not a neutral measure of ability at all; it functions to structurally exclude one sex by ratifying an existing division of labor within the household. To champion “women’s active participation” without revisiting this standard is to leave the barrier in place while claiming “anyone can enter.”<\/p>\n\n\n\n This barrier did not appear out of nowhere. The seniority-based, lifetime-employment model of Japanese employment that took shape during the high-growth era, together with the tax and social security systems that supported it \u2014 the spousal deduction (the so-called “\u00a51.03 million wall”) and the Category 3 insured-person system introduced in the 1985 pension reform \u2014 were all designed around a single unit: one male breadwinner supporting a household, with a woman as unpaid domestic labor. This is the logic of the Meiji-era ie<\/em> (household) system \u2014 which concentrated the family’s representative authority in a male household head \u2014 transplanted, after the legal abolition of that system in the 1947 Civil Code reform, into a different institutional apparatus: employment practice and the tax code. (This historical pathway is examined in detail in the companion essay, “The Invention of ‘Samurai Tradition.'”) The image of the “infinitely available worker,” implicitly assumed by today’s management track, is in fact a historically contingent standard built on this Meiji-derived model of domestic division of labor.<\/p>\n\n\n\n The M-Curve and the Problem of Restarting After Re-Entry<\/strong><\/p>\n\n\n\n The so-called M-curve \u2014 in which many women, after leaving the workforce for childbirth and childcare, are forced to re-enter as non-regular employees \u2014 has long been pointed out as a problem, yet institutional remedies (support for career development during leave, guaranteed positions upon return, expanded childcare infrastructure) have lagged behind other advanced economies. The buildout of childcare capacity was left neglected for years under the banner of the “waitlisted children” problem, only beginning to improve in recent years. To create “opportunity” on paper while failing to simultaneously build the infrastructure needed to actually use it is not mere delay \u2014 it reflects a genuine ordering of priorities.<\/p>\n\n\n\n The Absence of Quotas<\/strong><\/p>\n\n\n\n As the political data above makes clear, what the countries that have substantially raised their share of women in parliament have in common is the adoption of legal or intraparty candidate quotas. In Japan, the 2018 “Act on Promotion of Gender Equality in the Political Field” merely calls for equalizing candidate numbers as a “best-effort target,” with no penalties and no binding force. Likewise, the government’s target for women on Prime Market boards (30% by 2030) is framed as an aspirational best-effort obligation with no penalty for missing it.<\/p>\n\n\n\n None of this means “nothing is being done.” Targets exist. But the deliberate absence of any enforcement mechanism means this is better described not as inaction but as an active choice not to grant enforcement power<\/strong>. Setting targets while avoiding effective means of achieving them creates the appearance of responding to external pressure for change, while functioning to suppress the actual pace of that change.<\/p>\n\n\n\n The Historical Origin of the Gap in Political Capital<\/strong><\/p>\n\n\n\n The lag in the political sphere has yet another historical pathway distinct from employment practice. Women’s suffrage in Japan was granted in 1945 and first exercised in the 1946 general election; before that, under the Meiji constitutional order, women had no right to vote or to stand for election, ever. This was not so much a distinctly Japanese lag as a choice that placed Japan roughly in step with Western societies of the time \u2014 France did not grant women’s suffrage until 1944, Italy until 1945, and Switzerland not until 1971 at the federal level. The modern nation-state model itself was, in its formative period, designed on the premise that suffrage belonged to men; Meiji Japan essentially imported this international standard wholesale (see “The Invention of ‘Samurai Tradition'” for more detail). Political capital \u2014 party organizations, electoral strongholds, support-group networks, channels for political fundraising \u2014 accumulated exclusively in male hands throughout this long period of exclusion. The gap in starting position, already decisive by the time suffrage was granted, has been carried forward for eighty years since as a hereditary structure of candidate selection built on the “three ban” \u2014 jiban (local base), kanban (name recognition), kaban (money). Absent an enforcement mechanism like a quota, this accumulated gap will not close on its own.<\/p>\n\n\n\n In 2003, the Japanese government set the goal \u2014 commonly known as “202030” \u2014 of raising the share of women in leadership positions to roughly 30% by 2020. That target was missed, and the deadline was pushed back to 2030. As of 2024 the managerial share still stood at 13.1%, far short of the government’s own goal.<\/p>\n\n\n\n This pattern of “set a target, then postpone it” is not a one-off failure but a recurring structure. The fact that the cycle of setting a target, missing it, and extending the deadline has now continued for more than twenty years shows that the delay is not the result of unforeseen difficulty. It is a structurally scheduled delay, built into the very design of targets that never included any mechanism \u2014 penalties, legal force, quotas \u2014 to compel their achievement.<\/strong><\/p>\n\n\n\n Starting in April 2026, an amendment to the Act on Promotion of Women’s Active Engagement will make disclosure of women’s managerial ratios and similar figures mandatory. This is a step forward in that it strengthens external pressure through “visibility,” but mandatory disclosure is not the same as a mandatory outcome. As long as there is no penalty for continuing to publish a low number, this measure too remains an extension of the same “best-effort” approach that has defined policy so far.<\/p>\n\n\n\n This is the point to connect back to the discussion of family succession developed in the earlier essays. That discussion found a structure in which seemingly objective, neutral-sounding words \u2014 “bloodline,” “wisdom,” “institution” \u2014 were, in fact, tools conveniently reached for, again and again, to justify one fixed premise: sex. And as traced in “The Invention of ‘Samurai Tradition,'” the very norm that fixes “sex” in place was never even fully rooted in the actual practice of samurai society before the Edo period; it was a modern construct, selected by the Meiji state for reasons of governance convenience, reinforced with imported Western legal doctrine and state ideology, and imposed on the entire nation. The long-hours barrier to entry and the gap in political capital examined here are both results of that same Meiji-era construct surviving, in altered form, in employment practice, tax policy, and party organization, even after the legal ie<\/em> system was abolished in 1947.<\/p>\n\n\n\n A remarkably similar structure appears in today’s stagnation in the share of women in management, politics, and business. Ostensibly neutral, objective evaluation criteria \u2014 “ability,” “aptitude,” “attrition rate,” “tolerance for long hours” \u2014 are lined up, but these criteria function to justify an already-existing skewed distribution by sex as though it were a difference in ability. And the enforceable measures that would actively correct that skew \u2014 quotas, numerical targets backed by penalties \u2014 have been consistently avoided for more than forty years.<\/p>\n\n\n\n The gap between the formal promise of equal opportunity and the stark inequality of outcomes is neither accidental nor simply a matter of slow cultural change. It is an entirely predictable result of a consistent, repeated choice: set targets, but withhold any enforceable means of achieving them. The excuse that “women’s awareness hasn’t caught up yet” or “this kind of thing takes time” performs exactly the same function as the “ancestral wisdom” argument examined in the previous essay \u2014 shifting the burden of explanation away from a verifiable question of institutional design and onto a vague, hard-to-falsify question of “awareness” or “time.”<\/p>\n\n\n\n To explain the lack of progress in women’s advancement into management, politics, and business leadership by saying “opportunity is already equal, so the rest is a matter of women’s own attitude or effort” is not supported by the facts. Statistical discrimination functioning as a self-fulfilling prophecy; evaluation criteria that claim neutrality while remaining skewed in practice; an institutionalized long-hours barrier to entry; delayed investment in childcare infrastructure; and, above all, a consistent policy choice never to give targets any enforcement power \u2014 all of these, stacked together, produce today’s numbers.<\/p>\n\n\n\n The premise that “equal opportunity has already been achieved” is itself mistaken. Opportunity only becomes real once the conditions needed to exercise it \u2014 time, fair evaluation, the ability to sustain a career \u2014 are actually in place. To neglect that groundwork and then declare “the rest is up to the individual” is equivalent to shackling one runner’s leg at the starting line and then announcing “the rest is a fair competition based on ability.” What is needed to change this situation is not vague talk of “changing awareness,” but verifiable, concrete institutional design that compels achievement.<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Introduction: “Opportunity” Was Supposed to Already Be Equal The previous essay, “The Male-L […]<\/p>\n","protected":false},"author":1,"featured_media":750,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-749","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/www.junkatanuma.com\/index.php?rest_route=\/wp\/v2\/posts\/749","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.junkatanuma.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.junkatanuma.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.junkatanuma.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.junkatanuma.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=749"}],"version-history":[{"count":1,"href":"https:\/\/www.junkatanuma.com\/index.php?rest_route=\/wp\/v2\/posts\/749\/revisions"}],"predecessor-version":[{"id":751,"href":"https:\/\/www.junkatanuma.com\/index.php?rest_route=\/wp\/v2\/posts\/749\/revisions\/751"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.junkatanuma.com\/index.php?rest_route=\/wp\/v2\/media\/750"}],"wp:attachment":[{"href":"https:\/\/www.junkatanuma.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=749"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.junkatanuma.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=749"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.junkatanuma.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=749"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}II.
