The Wound of 'Attachment' Pervading Japanese Society — The Structural Problem Produced by Patriarchy, Nuclear Familization, and Intergenerational Transmission
219,170 cases of child abuse, 128,000 cases of domestic violence, 354,000 school refusals, 1.46 million social recluses — these statistics are not independent problems. They share a common root: the structural failure of attachment formation. This article examines the mechanisms of emotional suppression under the patriarchal household system, the isolation of childrearing driven by nuclear familization, and the intergenerational transmission of trauma.
What Is Happening
Online harassment of strangers, men deliberately bumping into women on train platforms, people directing anger at strollers and nursing covers in public spaces, social media posts demanding that snoring hospital patients "move to a private room" — phenomena that appear unrelated share, from a psychological perspective, a single common structure.
A dysfunction of self-other boundaries (boundaries).
Substituting "I am uncomfortable" for "this is a social nuisance," and demanding that others change. Perceiving someone else receiving consideration as "a loss for me." Underlying this pattern of response may be a problem with attachment — the relational bond that should form in early childhood.

Common Structural Source
Attachment formation failure × society-wide emotion dysregulation
Child abuse consultations have increased continuously for 32 years, reaching 219,170 cases in fiscal 2022. Domestic violence consultations reached approximately 128,000 in fiscal 2023 (Cabinet Office, DV Statistics). School refusal hit a record high of 354,000 students in fiscal 2024. Social reclusion is estimated at 1.46 million people (Cabinet Office, 2023). These statistics are frequently discussed as separate social problems. Yet when their structures are disaggregated, all of them can be seen as branching from a common source: the failure of attachment formation and emotional dysregulation.
Background and Context
What Is Attachment Disorder? DSM-5 Definitions and Attachment Styles
Attachment refers to the emotional bond formed between infants and their primary caregivers. The concept, proposed by John Bowlby, is not simply about "becoming fond of" someone; it forms the foundation of the Internal Working Model — the schema through which human beings construct interpersonal relationships throughout their lives.
In DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), attachment problems are classified into two diagnostic categories.
- Reactive Attachment Disorder (RAD): Emotional withdrawal and inhibition. Minimal sharing of emotions with attachment figures. Symptoms may ameliorate when the caregiving environment improves.
- Disinhibited Social Engagement Disorder (DSED): Indiscriminate attachment behavior toward strangers. Disregard for social boundaries.
Both diagnoses require, as a prerequisite, a history of inappropriate caregiving (neglect, abuse, or frequent changes of primary caregiver). The prevalence of RAD in the general population is estimated at approximately 1.4% (based on a review by Zeanah et al., 2022). Among children in institutional or foster care settings, RAD has been reported in 5–15% of cases, and DSED in up to 49% (Smyke et al., 2012, and related institutional care research).
Even below the clinical threshold of a diagnosable "disorder," however, skewed attachment styles that affect interpersonal relationship patterns are present far more broadly. The four-category model of Bartholomew & Horowitz (1991) classifies adult attachment styles as follows.
- Secure: Trust in both self and others. International average: 50–65%
- Preoccupied (Anxious-Ambivalent): Strong fear of abandonment; excessive dependence on others
- Dismissing (Avoidant): Avoidance of intimacy; preference for self-sufficiency
- Fearful-Avoidant: Desire for intimacy combined with fear of it; the most unstable style
Attachment Style: International Comparison
Based on infant Strange Situation studies
| Attachment Style | Intl. Avg. | Japan | W. Germany |
|---|---|---|---|
| Secure | 65% | 68% | 57% |
| Avoidant | 21% | ~5% | 35% |
| Resistant / Anxious | 14% | ~27% | 8% |
Note: Japan shows very low avoidant (~5%) but disproportionately high anxious-resistant (~27%)
Particularly noteworthy here is Japan's distinctive pattern. A meta-analysis by van IJzendoorn and Kroonenberg (1988) found that, while Japanese infants showed a secure attachment rate of 68% — close to the international average — avoidant attachment was extremely rare (approximately 5%), while anxious-resistant (ambivalent) attachment was exceptionally high at approximately 27%. This stands in sharp contrast to West Germany, which showed 35% avoidant attachment.
What does this cultural skew signify? It suggests a connection to relational patterns particular to Japanese society: "I want you to understand without being told," "please don't abandon me," "why don't you value me?"
The Problem of Co-Occurrence with Developmental Disorders
What further complicates the understanding of attachment disorders is the symptomatic overlap with developmental disorders (ASD and ADHD). Interpersonal difficulties, emotional dysregulation, and attentional impairments are common to attachment disorders, ASD, and ADHD alike.
The decisive difference lies in environmental responsiveness. Attachment disorders tend to improve when the caregiving environment improves (Smyke et al., Bucharest Early Intervention Project), whereas ASD, being rooted in neurological foundations, shows limited improvement in response to environmental change.
In Japanese clinical settings, however, this differential diagnosis is frequently insufficient. As psychiatrist Takashi Okada notes in Attachment Disorder: People Dragging the Burden of Childhood (Kobunsha Shinsho, 2011), misdiagnosis — in which attachment disorders are subsumed under ASD or ADHD — occurs with regularity. The concept of "Developmental Trauma Disorder (DTD)," proposed by Bessel van der Kolk around 2005, was a framework designed to address this problem, but its inclusion in DSM-5 was rejected. "Complex PTSD (C-PTSD)" in ICD-11 now functions as a de facto substitute.
More serious still is the vicious cycle between developmental disorders and attachment disorders.
Developmental disorder characteristics → Difficulty in being parented → Abuse/neglect → Formation of attachment disorder → Exacerbation of characteristics → Difficulty parenting in the next generation
Data from the Ministry of Education, Culture, Sports, Science and Technology show that the number of students in special-needs classes increased from approximately 63,000 in 2003 to 395,000 in 2024 — a 6.3-fold increase (MEXT, 2024). Even in mainstream classrooms, 8.8% of students are assessed as requiring "special educational support" (MEXT, 2022 survey). While part of this increase reflects rising diagnostic rates, an increase in acquired developmental difficulties stemming from inappropriate caregiving environments cannot be ruled out entirely.
The Historical Structure: The Seeds Planted by the Household System
Why has the problem of attachment become so structurally entrenched in Japan? Its origins reach back to the household system (ie seido) institutionalized under the Meiji Civil Code of 1898.
Under the household system, the head of household (patriarch) held broad authority over marriage, adoption, and place of residence, and family relationships were defined not by affection but by role and obligation. Messages such as "men don't cry" and "don't be weak" were transmitted across generations, structurally suppressing emotional expression. Mothers were subordinated to the household while bearing sole responsibility for childcare; fathers were structurally excluded from childrearing.
The household system was legally abolished by the postwar Civil Code reform of 1947, but the psychological norms of "family shame," "social appearances," and prescriptions about how men and women should behave persisted throughout the Showa era. This psychological residue, as Nakazawa & Shwalb (2020) note, aligns with the mythology — actively promoted by the government during both the Meiji period and the postwar era — that "mothers are biologically more prepared for the strong responsibility of childrearing."
The structural effects of patriarchy on attachment formation operate at four levels.
- Suppression of emotional expression: Fathers were expected to embody authority, functioning as a mechanism that reinforced avoidant attachment
- Overburden on mothers: The full-time housewife model depleted mothers' emotional reserves, obstructing sensitive responsiveness in caregiving
- Primacy of vertical relationships: Parent-child relationships defined by "role and duty" created environments in which emotional safe havens were difficult to form
- Exclusion of men from childcare: The gendered division of "fathers work, mothers raise children" eliminated opportunities for father-child attachment formation
Postwar nuclear familization further exacerbated this structure. Three-generation co-resident households declined from approximately 30% in 1960 to approximately 7% in 2020 (National Institute of Population and Social Security Research, 2022). The natural circuits of alloparenting (shared childcare) provided by grandparents and community networks were lost, advancing the isolation of mothers in childrearing.
Trends in child abuse consultations mirror these structural changes. From 1,101 cases in fiscal 1990 to approximately 199 times that figure over 32 years — an increase rate that cannot be explained by rising awareness alone. Examining the 2022 breakdown, psychological abuse constitutes 59.1% of cases — the largest category — indicating that invisible "emotional neglect" is more prevalent than visible physical violence.
Intergenerational Transmission: How Trauma Is Passed On
The mechanisms by which attachment problems are transmitted across generations are explained through three pathways.
Intergenerational Trauma Cycle
Inadequate caregiving
Patriarchy, isolated parenting, neglect
Attachment failure
Anxious / avoidant / disorganized formation
Emotion regulation difficulty
Blurred self-other boundaries
Adult relationship problems
DV, moral harassment, overcontrol
Reproduction in next generation
Parenting difficulty → child's attachment disorder
Epigenetic Transmission
Through DNA methylation patterns, HPA-axis stress response vulnerability may be biologically transmitted to the next generation
Kaufman & Zigler (1987): About 30% (±5%) of parents with abuse history go on to abuse their own children
First, behavioral transmission. A parent's attachment style exerts a strong influence on a child's attachment style. Research on the Adult Attachment Interview (AAI) by Main & Hesse (1990) demonstrated that when parents carry unresolved trauma or loss, they unconsciously exhibit "frightening or fear-inducing" behaviors in interactions with infants, forming disorganized (Type D) attachment. Research by Mari Kubota (National Institute of Population and Social Security Research) indicates that even in caregiving environments without abuse, 15% of infants show Type D attachment, with the primary cause identified as unresolved trauma in the caregiver.
Second, biological transmission through epigenetic mechanisms. Research on Holocaust survivors and their descendants has shown that the methylation patterns of the FKBP5 gene — involved in stress response — are associated across generations (Yehuda & Lehrner, 2018). Stress exposure during pregnancy affects fetal HPA axis (stress response system) development via the placenta, and mitochondrial dysfunction in the brain may also be involved in intergenerational trauma transmission (Picard & McEwen, 2021, Communications Biology).
Third, sociostructural transmission. As long as patriarchal values are institutionally preserved, individual-level attachment repair within families is structurally obstructed. Kaufman & Zigler (1987) estimated that approximately 30% (±5%) of parents with histories of abuse go on to abuse their own children. The intergenerational transmission rate is not 100%, but it is significantly higher than the general population abuse rate.
Here a hypothesis emerges. The generation-skipping effect of intergenerational trauma is said to diminish from the third generation onward, counting from the postwar "adult children" generation. In 2026, that "third generation" is precisely at the age when they are becoming parents. The increases in abuse, school refusal, and social reclusion appearing in the statistics may reflect the intergenerational cascade reaching its peak.
Reading the Structure
The Collapse of "Amae" and the Problem of Boundaries
"Amae" no Kōzō (The Anatomy of Dependence), written in 1971 by psychiatrist Takeo Doi, is a classic work that analyzes through psychoanalytic lenses the concept of amaeru — a term unique to Japanese. According to Doi, the essence of amae is "acting in a dependent manner toward another while understanding that the other holds goodwill." It is a psychological dynamic that "denies the existential reality of the separation between self and other, seeking to transcend the pain of separation."
In connection with Bowlby's attachment theory, amae functions as an extension of secure dependency, operating as part of normal development — provided that the certainty of a secure base is guaranteed.
The problem arises when the secure base is uncertain — that is, when attachment becomes destabilized. Because the psychology of amae presupposes an undifferentiated self-other relationship, the absence of a secure base manifests as one-sided demands for dependence, violation of others' autonomy, and the avoidance of verbal articulation in favor of "I want you to understand without being told."
Self-Other Boundary Dysfunction Patterns
Healthy Amae (with secure base)
- Mutual consideration and trust
- Verbalized dependency
- Respect for autonomy
Pathological transformation (no secure base)
- Demanding others "read my mind"
- Invasion of others' autonomy
- "My discomfort = society's problem"
The social phenomena noted at the outset can be reread through this framework.
- "The snoring is a nuisance; move to a private room" → A boundary violation in which one's own discomfort is resolved by demanding behavioral change from another
- "Strollers are in the way" / "Nursing covers are unpleasant" → A sense of relative deprivation — feeling that one is at a disadvantage when others receive consideration
- Online attacks and pile-ons → Displaced aggression produced by the disinhibiting effect of anonymity combined with attachment anxiety
Research supports this connection. Insecure attachment (anxious or avoidant) is significantly and positively associated with problematic and dependent use of social media (D'Arienzo et al., 2019). Individuals with anxious attachment exhibit higher levels of FOMO (fear of missing out) and heightened sensitivity to exclusion, increasing the risk of aggressive online behavior. The pathway identified in Zhang et al. (2023) — upward social comparison on social media → relative deprivation → hostile attribution bias → aggressive behavior — is the very psychological mechanism of "someone is benefiting, therefore I am losing out."
Distinguishing Attachment Problems from the Need for Approval
One conflation requires clarification here. Aggressive behavior on social media and excessive self-promotion are frequently dismissed as a "strong need for approval," but attachment problems and the need for approval belong to entirely different conceptual levels.
In Maslow's hierarchy of needs, the need for esteem (Esteem Needs) occupies the fourth level as a normal psychological need. Attachment, by contrast, concerns the third level — love and belonging — and further, the second level — safety needs — that underlies it. As Maslow himself wrote in Motivation and Personality (1954): "The most common basis of maladjustment and psychopathology is the thwarting of the love needs." Attachment problems thus occupy a more fundamental level.
What is critical is the direction of causality. Attachment anxiety, by undermining a stable Internal Working Model, pathologically increases dependence on external sources of validation. In other words, an excessive need for approval is not the cause; it may be appearing as a symptom of attachment anxiety.
Misreading this distinction leads to the superficial prescription of "exercise more self-control over your need for approval." What is structurally required is the (re)construction of a secure base for attachment.
"Emotional Abuse as Japan's Infrastructure" — The Overall Structure
Integrating the foregoing analysis, a structural hypothesis emerges.
The Meiji patriarchal system laid the cultural foundation for the suppression of emotional expression; postwar nuclear familization eliminated alloparenting; and the "fathers work, mothers raise children" model of the high-growth era normalized the isolation of mothers in childrearing. The convergence of these three structural shifts has caused Japanese society to reproduce, over decades, an environment in which attachment formation is structurally impeded.
This structure is being transmitted intergenerationally through both behavioral and epigenetic pathways. If the approximately 30% intergenerational transmission risk among parents with histories of abuse (Kaufman & Zigler, 1987) accumulates over multiple generations, the consequences are incalculable.
That the rate of reported workplace power harassment (power harassment) in Japan stands at 32.5% (Ministry of Health, Labour and Welfare, 2016 survey; still 31.4% in the 2020 survey) can be read as the inevitable outcome of a patriarchal vertical authority structure — the transposition of the ie-system parent-child hierarchy into the workplace. The psychological control of subordinates by superiors, and the violation of their boundaries, is nothing other than insecure attachment styles and ambiguous self-other boundaries being re-enacted within organizations.
The expression "emotional abuse as Japan's infrastructure" is, from the perspective of structural analysis, not an exaggeration. The behavioral pattern of invoking self-reliance rhetoric to demand endurance from the vulnerable while averting one's gaze from fundamental problem-solving itself functions as a defense mechanism by which individuals without a secure base maintain a "provisional stability" within society.
Directions for Recovery — Individual and Social
Can attachment problems be "healed"? To speak candidly, it is not easy. Even psychiatrists and welfare professionals acknowledge the difficulty. Nevertheless, the accumulation of evidence-based interventions continues to advance steadily.
At the individual level, attachment-focused psychotherapies — attachment therapy, EMDR, and schema therapy — have demonstrated effectiveness. Research applying Young et al.'s schema therapy to Japanese contexts (MDPI, 2024) identifies a distinctive pattern of the "punitive parent mode" in collectivist societies and argues for the necessity of culturally adapted therapeutic approaches.
At the social level, three directions are discernible.
- Structural resolution of isolated childrearing: Expansion of postnatal care facilities, substantive implementation of comprehensive family support centers (Child and Family Support Centers), and community-based alloparenting networks
- Institutionalization of early intervention: Attachment screening at infant health checkups, dissemination of parent training, and trauma care for caregivers
- Social embedding of emotional literacy: Systematic introduction of Social and Emotional Learning (SEL) in school education. The development of emotional regulation skills can function as an alternative secure base for children who lacked a genuine one
Yet the most fundamental challenge is to resist the individualization trap — reducing this problem to "personal character" or "poor parenting." Attachment disorder is a structural product generated by social structures, and addressing it requires structural approaches.
The numbers reflect the structure. 219,000 child abuse consultations, 354,000 school refusals, 1.46 million social recluses. Simply lamenting that these numbers "are rising" changes nothing. The question being posed is how to reorganize the social structures that have impeded attachment formation over decades.
