hikikomori hikikomori hikikomori (japanese: ひきこもり or 引きこもり, lit. "pulling inward, being confined"), also known as severe social withdrawal, is total withdrawal from society and seeking extreme degrees of social isolation and confinement. hikikomori refers to both the phenomenon in general and the recluses themselves. hikikomori have been described as loners or "modern-day hermits". estimates suggest that half a million japanese youths have become social recluses, as well as more than half a million middle-aged individuals. a young japanese man living as a hikikomori in 2004 definition the japanese ministry of health, labour, and welfare defines hikikomori as a condition in which the affected individuals refuse to leave their parents' house, do not work or go to school and isolate themselves away from society and family in a single room for a period exceeding six months. the psychiatrist tamaki saitō defines hikikomori as "a state that has become a problem by the late twenties, that involves cooping oneself up in one's own home and not participating in society for six months or longer, but that does not seem to have another psychological problem as its principal source". more recently, researchers have developed more specific criteria to more accurately identify hikikomori. during a diagnostic interview, trained clinicians evaluate for: spending most of the day and nearly every day confined to home, marked and persistent avoidance of social situations, and social relationships, social withdrawal symptoms causing significant functional impairment, duration of at least six months, and no apparent physical or mental etiology to account for the social withdrawal symptoms. the psychiatrist alan teo first characterized hikikomori in japan as modern-day hermits, while the literary and communication scholar flavio rizzo similarly described hikikomori as "post-modern hermits" whose solitude stems from ancestral desires for withdrawal. while the degree of the phenomenon varies on an individual basis, in the most extreme cases, some people remain in isolation for years or even decades. often hikikomori start out as school refusers, or futōkō (不登校) in japanese (an older term is tōkōkyohi (登校拒否)). hikikomori has been defined by a japanese expert group as having the following characteristics: spending most of the time at home no interest in going to school or working persistence of withdrawal for more than 6 months exclusion of schizophrenia, intellectual disability, and bipolar disorder exclusion of those who maintain personal relationships (e.g., friendships) common traits while many people feel the pressures of the outside world, hikikomori react by complete social withdrawal. in some more severe cases, they isolate themselves in their bedrooms for months or years at a time. they usually have few or no friends. in interviews with current or recovering hikikomori, media reports and documentaries have captured the strong levels of psychological distress and angst felt by these individuals. while hikikomori favor indoor activities, some venture outdoors occasionally. the withdrawal from society usually starts gradually. affected people may appear unhappy, lose their friends, become insecure and shy, and talk less. prevalence according to japanese government figures released in 2010, there were at that time 700,000 individuals living as hikikomori within japan, with an average age of 31. (population of japan in 2014 was 127.3 million.) still, the numbers vary widely among experts. these included the hikikomori who were at that time in their 40s and had spent 20 years in isolation. this group is generally referred to as the "first-generation hikikomori". there is concern about their reintegration into society in what is known as "the 2030 problem", when they will be in their 60s and their parents begin to die. additionally, the government estimates that 1.55 million people are on the verge of becoming hikikomori. tamaki saitō, who first coined the phrase, originally estimated that there may be over one million hikikomori in japan, although this was not based on national survey data. nonetheless, considering that hikikomori adolescents are hidden away and their parents are often reluctant to talk about the problem, it is extremely difficult to gauge the number accurately. a 2015 cabinet office survey estimated that 541,000 recluses aged 15 to 39 existed. in 2019, another survey showed that there are roughly 613,000 people aged 40 to 64 that fall into the category of "adult hikikomori", which japan's welfare minister takumi nemoto referred to as a "new social issue". while hikikomori is mostly a japanese phenomenon, cases have been found in the united states, the united kingdom, oman, spain, germany, italy, india, sweden, south korea, and france. hypotheses on cause developmental and psychiatric conditions hikikomori is similar to the social withdrawal exhibited by some people with autism spectrum disorders, a group of developmental disorders that include asperger syndrome, pdd-nos and "classic" autism. this has led some psychiatrists to suggest that hikikomori may be affected by autism spectrum disorders and other disorders that affect social integration, but that their disorders are altered from their typical western presentation because of japanese sociocultural pressures. suwa & hara (2007) discovered that 5 of 27 cases of hikikomori had a high-functioning pervasive developmental disorder (hpdd), and 12 more had other disorders or mental diseases (6 cases of personality disorders, 3 cases of obsessive-compulsive disorder, 2 cases of depression, 1 case of slight intellectual impairment); 10 out of 27 had primary hikikomori. the researchers used a vignette to illustrate the difference between primary hikikomori (without any obvious mental disorder) and hikikomori with hpdd or other disorder. alan teo and colleagues conducted detailed diagnostic evaluations of 22 individuals with hikikomori and found that while the majority of cases fulfilled criteria for multiple psychiatric conditions, about 1 in 5 cases were primary hikikomori. to date, however, hikikomori is not included in the dsm-5 (the diagnostic and statistical manual of mental disorders), due to insufficient data. according to michael zielenziger's book, shutting out the sun: how japan created its own lost generation, the syndrome is more closely related to posttraumatic stress disorder. the author claimed that the hikikomori interviewed for the book had discovered independent thinking and a sense of self that the current japanese environment could not accommodate. the syndrome also closely parallels the terms avoidant personality disorder, schizoid personality disorder, schizotypal personality disorder, agoraphobia or social anxiety disorder (also known as "social phobia"). social and cultural influence sometimes referred to as a social problem in japanese discourse, hikikomori has a number of possible contributing factors. alan teo has summarized a number of potential cultural features that may contribute to its predominance in japan. these include tendencies toward conformity and collectivism, overprotective parenting, and particularities of the educational, housing and economic systems. severe social withdrawal in japan appears to affect men and women equally. however, because of differing social expectations for maturing boys and girls, the most widely reported cases of hikikomori are from middle- and upper-middle-class families; sons, typically their eldest, refuse to leave the home, often after experiencing one or more traumatic episodes of social or academic failure. in the anatomy of dependence, takeo doi identifies the symptoms of hikikomori, and explains its prevalence as originating in the japanese psychological construct of amae (in freudian terms, "passive object love", typically of the kind between mother and infant). other japanese commentators such as academic shinji miyadai and novelist ryū murakami, have also offered analysis of the hikikomori phenomenon, and find distinct causal relationships with the modern japanese social conditions of anomie, amae and atrophying paternal influence in nuclear family child pedagogy. young adults may feel overwhelmed by modern japanese society, or be unable to fulfill their expected social roles as they have not yet formulated a sense of personal honne and tatemae – one's "true self" and one's "public façade" – necessary to cope with the paradoxes of adulthood. the dominant nexus of hikikomori centres on the transformation from youth to the responsibilities and expectations of adult life. indications are that advanced industrialized societies such as modern japan fail to provide sufficient meaningful transformation rituals for promoting certain susceptible types of youth into mature roles. as do many societies, japan exerts a great deal of pressure on adolescents to be successful and perpetuate the existing social status quo. a traditionally strong emphasis on complex social conduct, rigid hierarchies and the resulting, potentially intimidating multitude of social expectations, responsibilities and duties in japanese society contribute to this pressure on young adults. historically, confucian teachings de-emphasizing the individual and favouring a conformist stance to ensure social harmony in a rigidly hierarchical society have shaped much of east asia, possibly explaining the emergence of the hikikomori phenomenon in other east asian countries. in general, the prevalence of hikikomori tendencies in japan may be encouraged and facilitated by three primary factors: middle class affluence in a post-industrial society such as japan allows parents to support and feed an adult child in the home indefinitely. lower-income families do not have hikikomori children because a socially withdrawing youth is forced to work outside the home. the inability of japanese parents to recognize and act upon the youth's slide into isolation; soft parenting; or codependency between mother and son, known as amae in japanese. a decade of flat economic indicators and a shaky job market in japan makes the pre-existing system requiring years of competitive schooling for elite jobs appear like a pointless effort to many. role of modern technology although the connection between modern communication technologies (such as the internet, social media and video games) and the phenomenon is not conclusively established, those technologies are considered at least an exacerbating factor that can deepen and nurture withdrawal. previous studies of hikikomori in south korea and spain found that some of them showed signs of internet addiction, though researchers do not consider this to be the main issue. however, according to associate professor of psychiatry at kyushu university in fukuoka, takahiro kato, video games and social media have reduced the amount of time that people spent outside and in social environments that require direct face to face interaction. the emergence of mobile phones and then smartphones may also have deepened the issue, given that people can continue their addiction to gaming and online surfing anywhere, even in bed. japanese education system the japanese education system, like those found in china, singapore, india, pakistan and south korea, puts great demands upon youth. a multitude of expectations, high emphasis on competition, and the rote memorization of facts and figures for the purpose of passing entrance exams into the next tier of education in what could be termed a rigid pass-or-fail ideology, induce a high level of stress. echoing the traditional confucian values of society, the educational system is viewed as playing an important part in society's overall productivity and success. in this social frame, students often face significant pressure from parents and the society in general to conform to its dictates and doctrines. these doctrines, while part of modern japanese society, are increasingly being rejected by japanese youth in varying ways such as hikikomori, freeter, neet (not currently engaged in employment, education, or training), and parasite singles. the term "hodo-hodo zoku" (the "so-so tribe") applies to younger workers who refuse promotion to minimize stress and maximize free time. beginning in the 1960s, the pressure on japanese youth to succeed began successively earlier in their lives, sometimes starting before pre-school, where even toddlers had to compete through an entrance exam for the privilege of attending one of the best pre-schools. this was said to prepare children for the entrance exam of the best kindergarten, which in turn prepared the child for the entrance exam of the best elementary school, junior high school, high school, and eventually for their university entrance exam. many adolescents take one year off after high school to study exclusively for the university entrance exam, and are known as ronin. more prestigious universities have more difficult exams. the most prestigious university with the most difficult exam is the university of tokyo. since 1996, the japanese ministry of education has taken steps to address this 'pressure-cooker' educational environment and instill greater creative thought in japanese youth by significantly relaxing the school schedule from six-day weeks to five-day weeks and dropping two subjects from the daily schedule, with new academic curricula more comparable to western educational models. however, japanese parents are sending their children to private cram schools, known as juku, to 'make up' for lost time. after graduating from high school or university, japanese
