Hikikomori ( , ) are reclusive adolescents or adults who withdraw from social life, often seeking extreme degrees of isolation and confinement. The term refers to both the sociological phenomenon in general and the individuals belonging to this societal group, who have been described as "modern hermits". Hikikomori has been an increasing problem in Japan since the 1990s, with estimates suggesting that over a million individuals are affected. While the phenomenon is most associated with Japan, cases with similar conditions have also been reported in other parts of the world.
The key characteristics of hikikomori include a marked avoidance of social situations and interaction, a retreat into one's home (often a single room) for at least six months, and significant functional impairment or distress. While not a formal psychiatric diagnosis in itself, hikikomori can co-occur with various mental health conditions such as depression, anxiety disorders, or developmental disorders. The etiology is complex and multifaceted, involving individual psychological vulnerabilities (such as a history of bullying or academic failure, and personality traits like introversion or high sensitivity to shame), familial dynamics (including parent-child relationships and communication issues), and broader societal pressures related to education, employment, and social expectations in contemporary societies.
The understanding and societal response to hikikomori have evolved, with various support systems and treatment approaches being explored. The issue raises significant concerns regarding individual well-being, family burden, and the social integration of a considerable segment of the population.
Etymology and definition The Japanese term hikikomori (引きこもり or ひきこもり) is composed of the verbs hiku (引く, "to pull, draw, retreat") and komoru (籠る, "to shut oneself up, stay inside"). It describes both the condition of severe social withdrawal and the individuals who experience it. Psychiatrist Tamaki Saitō, who extensively researched and popularized the term with his 1998 book Shakaiteki Hikikomori: Owaranai Shishunki (Social Hikikomori: Adolescence without End), provided an early influential definition:
Saitō's initial definition emphasized hikikomori as a primary form of social withdrawal, distinct from other mental illnesses, although he later acknowledged that psychiatric treatment might be necessary. The Japanese Ministry of Health, Labour and Welfare (MHLW) in its 2003 guideline (updated in 2010) described hikikomori as a "psycho-sociological phenomenon" rather than a single disease entity, characterized by withdrawal from social participation (school, work, interactions outside home) and staying at home for more than six months, typically affecting individuals under 30. The MHLW guidelines also noted that while hikikomori is principally a non-psychotic phenomenon, it may co-occur with conditions like schizophrenia.
A more recent consensus among psychiatrists, as summarized by , defines hikikomori as:
This definition explicitly recognizes that hikikomori can co-occur with other mental disorders, differing from Saitō's earlier emphasis on it as a primary condition. The term is used to describe both the phenomenon and the individuals affected by it.
Characteristics The primary characteristic of hikikomori is a state of severe social withdrawal where individuals confine themselves to their homes, often to a single room, for extended periods, typically six months or longer.; ; ; ; ; ; This isolation involves a marked avoidance of social participation, such as attending school or work, and a reluctance to engage in social interactions even with family members.
Common behavioral patterns include a reversal of sleep-wake cycles (sleeping during the day and being active at night), excessive time spent on solitary activities like using the internet, playing video games, or watching television, and sometimes neglecting personal hygiene. While some may occasionally leave home for specific purposes, such as visiting a convenience store, their overall social engagement remains extremely limited. Some hikikomori individuals may also exhibit aggressive or violent behavior within the household, though this is not a universal characteristic.
Psychologically, individuals in hikikomori often experience significant distress. This can manifest as feelings of shame, inadequacy, anxiety, depression, and a profound sense of apathy or loss of motivation. Fear of others (anthropophobia) and obsessive-compulsive tendencies can also accompany the withdrawal. Saitō noted that many cases involve individuals who were initially perceived as "good" or introverted children who did not go through a typical rebellious phase. However, he also emphasized that there is not one fixed personality trait that manifests in every case. The experience often involves a loss of connection with the future, as described by Kazuki Ueyama: "The present was everything. I didn't have the ability to think about the future".
The phenomenon predominantly affects males, with Saitō reporting that 80% of the cases he dealt with were men. Government surveys also indicate a higher prevalence in males; for example, the 2016 Cabinet Office survey found 63.3% of hikikomori aged 15–39 were men, and the 2019 survey for those aged 40–64 found 76.6% were men. While often associated with adolescents and young adults, with onset typically occurring in the mid-teens to late twenties, hikikomori can persist for many years, leading to an aging population of individuals in withdrawal, sometimes referred to as the "80-50 problem" (parents in their 80s caring for hikikomori children in their 50s).
Prevalence Estimating the exact number of hikikomori in Japan is challenging due to the hidden nature of the condition and the shame often associated with it. Psychiatrist Tamaki Saitō, in his 1998 book, suggested that there could be "hundreds of thousands of people" living in this state, a figure that was significantly higher than previous estimates and sparked wider public and media attention. He later posited the number could be around or even over one million.
Japanese government surveys have provided varying estimates for different age groups.
A 2010 Cabinet Office survey estimated 696,000 hikikomori aged 15 to 39. A 2016 Cabinet Office survey reported an estimated 541,000 individuals in the same 15–39 age group. The apparent decrease was considered potentially misleading as it did not account for the aging of the hikikomori population beyond this surveyed age range. This survey found that 34.7% of these hikikomori had been in withdrawal for more than seven years, a significant increase from 16.9% in the 2010 survey. A 2019 Cabinet Office survey focusing on the 40–64 age group estimated 613,000 hikikomori individuals. This survey highlighted the issue of prolonged withdrawal and the "80-50 problem" (parents in their 80s caring for hikikomori children in their 50s).
Combining these figures, media reports in 2019 suggested that over one million people in Japan were living as hikikomori. These surveys often define hikikomori as staying at home for six months or more and not participating in school, work, or social interactions outside the family. However, the majority of those identified as hikikomori in these surveys do leave their homes occasionally (e.g., for hobbies or to go to a convenience store), with only a small percentage (e.g., 4.2% of the 40–64 age group in the 2019 survey) never leaving their rooms. The stigma associated with hikikomori and the methodological challenges of surveying a reclusive population mean that official figures may still underestimate the true prevalence of the condition. Saitō himself maintained that the total figure was likely between one million and 1.5 million, even after the 2010 government survey.
Contributing factors The development of hikikomori is understood to be a result of a complex interplay of societal, familial, and individual factors, rather than a single cause.
Societal factors
Several aspects of modern Japanese society are considered to contribute to the phenomenon. The highly competitive and rigid Japanese educational system is often cited as a major stressor. Tamaki Saitō argues that the system fosters an illusion of infinite possibilities while simultaneously imposing uniform evaluation standards. This can lead to intense pressure, bullying, and a fear of failure, making it difficult for some individuals to develop a stable sense of self or find their place. School non-attendance (futōkō) is often a precursor to or an early stage of hikikomori.
Changes in the labor market since the economic stagnation of the 1990s, including the decline of the traditional lifetime employment model, have made it harder for young people to secure stable, full-time jobs. The rise of precarious work (freeter) and individuals Not in Education, Employment, or Training (NEETs) reflects these difficulties. The pressure to succeed in a narrow definition of a "normal" life path (education followed by stable employment and marriage) can be overwhelming for those who deviate or struggle to meet these societal expectations.
Furthermore, the Japanese welfare system traditionally relied heavily on corporations (corporate welfare) and families to provide life security, with a less developed public social safety net for working-age individuals compared to some Western countries. As corporate welfare has shrunk, the burden on families to support non-working adult children has increased. This "familialistic welfare regime" can trap individuals in a state of dependency within the home, especially when public support systems are insufficient or carry a strong stigma.
Familial factors Family dynamics play a significant role in the development and maintenance of hikikomori. Saitō described a common pattern of an overly close or codependent mother-child relationship and an emotionally or physically absent father. In such families, the child may struggle to achieve psychological separation and independence. This over-reliance on the maternal figure, often termed amae (a desire for indulgent dependency), can hinder maturation.
Communication problems within the family, including a lack of open dialogue or an inability to address conflicts constructively, can exacerbate the isolation. The family, often out of shame or a sense of responsibility, may inadvertently enable the withdrawal by providing for the individual's needs without encouraging social reintegration, creating what Saitō termed the "hikikomori system". This system involves a breakdown of communication and a state where the individual, family, and society lose functional contact with one another.
Individual factors Individual psychological vulnerabilities can also predispose a person to hikikomori. These may include a history of bullying, academic or social failures, difficulties in interpersonal relationships, or pre-existing mental health conditions such as depression, anxiety disorders, or developmental disabilities like autism spectrum disorder, although hikikomori itself is not solely defined by these conditions.
Personality traits such as introversion, high sensitivity, perfectionism, or a strong fear of shame and failure can make individuals more susceptible to social withdrawal in the face of perceived social pressures or setbacks. Saitō's concept of "adolescence without end" suggests that some individuals in hikikomori are stuck in a prolonged adolescent state, unable to transition to adult roles and responsibilities. The experience of shame (haji) and social stigma associated with not conforming to societal expectations often becomes a powerful force maintaining the withdrawal. Individuals may feel a profound loss of self-worth and develop a deep-seated fear of judgment from others.
