Six Months Inside, and Sometimes Decades
About 1.46 million people in Japan live with hikikomori, according to recent government surveys. The estimate, described as roughly 2 percent of the population, captures a form of severe social withdrawal that lasts at least six months and can continue for years. Some people rarely leave a bedroom. Others occasionally venture outside but remain largely separated from work, education and personal relationships.

Psychologist Tamaki Saito brought the phenomenon to public attention in the 1990s, when the estimated number affected in Japan was one million. The newer estimate is 460,000 higher, an increase of about 46 percent. Alongside that numerical change, the profile has widened from the adolescent boys and young men initially associated with hikikomori to include women, people in middle age and individuals living alone.
Japan remains central to understanding the condition, but researchers have identified similar patterns in Australia, Bangladesh, India, Iran, South Korea, Taiwan, Thailand and the United States. People elsewhere may recognize the experience of prolonged withdrawal without knowing its Japanese name.
COVID-19 restrictions added another dimension. An Italian study examining 7,500 teenagers between 2019 and 2022 found that the number who never saw friends doubled in the years after pandemic restrictions. Meanwhile, a documented treatment case involving a Japanese man called Akira suggests that therapy delivered online can help someone begin returning to social life after years of seclusion.
These developments connect several parts of the same problem: how withdrawal begins, why it lasts, how families sustain someone through it and how treatment can reach a person who finds leaving home overwhelming. The central challenge is to understand each person's circumstances while recognizing a pattern now being studied across countries.
What Hikikomori Looks Like
Hikikomori comes from Japanese terms meaning to withdraw and to stay inside. Its defining feature is severe social withdrawal lasting six months or longer. At its most restrictive, a person confines themselves to one room, often in a parental home or an apartment where they live alone, and avoids social engagement.
Saito initially described the experience as an adolescence without end: a retreat from adult responsibilities and the demands of modern life. Competitive schooling, intense workplace expectations, high family expectations and pressure to conform can combine with personal vulnerabilities to make ordinary participation feel unbearable.
Daily routines may become reversed. A person sleeps during daylight and stays awake at night, spending much of that time gaming, browsing the internet or watching television. Personal hygiene and household maintenance can deteriorate. These changes can make returning to school, work or contact with other people increasingly difficult.
Families often provide the practical support that makes prolonged withdrawal possible. Relatives may leave meals outside a bedroom door and protect the person from demands coming from outside the home. Researchers describe a paradoxical stability: the individual remains in a state of near inactivity, supported by family structures from which they have withdrawn.
Parents and other relatives therefore occupy a difficult position. Their care meets immediate needs, while the household's routines can also help isolation continue. The behavior is understood as a complex response involving psychological and social pressures, rather than simply laziness or rebellion.
Severity varies. Some people almost never leave their rooms and rarely speak even to relatives. Others occasionally go outside and keep limited contact. Viewing hikikomori as a spectrum means considering both the extent of confinement and its effect on daily functioning, rather than treating everyone who withdraws as having the same needs.
How the Research Crossed Borders
A 2011 study asked psychiatrists in nine countries whether they had encountered patients with symptoms consistent with hikikomori. The countries were Australia, Bangladesh, India, Iran, Japan, South Korea, Taiwan, Thailand and the United States. Similar patterns of extreme withdrawal appeared in every country examined, particularly in urban areas.
Differences between countries were not statistically significant in that study. In simple terms, the researchers did not identify a sufficiently clear difference to support the idea that this pattern belonged exclusively to one national culture. The findings challenged the earlier view of hikikomori as a condition confined to Japan's social structures.
Research has since widened the geographical picture. A 2025 analysis concluded that hikikomori was a common problem across East Asia and Western nations. Denmark and other Scandinavian countries remained a gap: the condition had not been formally described there, and recent calls for investigation highlighted the need to examine prolonged withdrawal in those settings.
The development of the research can be followed through several dates:
- In the 1990s, Tamaki Saito brought hikikomori to public attention, with an estimate of one million people affected in Japan.
- In 2011, psychiatrists surveyed across nine countries identified similar patterns of severe social withdrawal.
- From 2019 to 2022, an Italian study examined changes in social behavior among 7,500 teenagers across the pandemic period.
- From 2020, COVID-19 restrictions created circumstances in which staying home and reducing contact became part of everyday life.
- In 2025, an analysis described hikikomori as a problem affecting East Asia and Western nations.
The international findings broaden the explanation for withdrawal. Japanese educational and workplace pressures remain relevant, but personal vulnerability and demanding social environments can meet in many places. Researchers increasingly examine that combination rather than relying on a single cultural explanation.
Why the Percentages Vary So Much
Studies have produced a wide range of prevalence estimates. Research on Japan's general population has reported rates from 0.87 percent to 1.2 percent, while some research involving student populations has reported a figure as high as 26.66 percent. Those findings sit alongside the more recent government estimate of approximately 1.46 million people, described as roughly 2 percent.
Figures reported elsewhere include 6.6 percent in China, 1.9 percent in Hong Kong, 2.3 percent in Korea, 20.9 percent in Singapore, 9.5 percent in Nigeria, 2.7 percent in the United States and 9 percent in Taiwan. Together, they show how widely researchers have investigated the pattern and how much their estimates vary.
Study design helps explain the range. Researchers may use different rules for deciding who qualifies, different questionnaires or assessments, and different ways of recruiting participants. A study of students examines a different group from a survey designed to represent a country's general population.
Readers therefore need to understand what each percentage describes. Inclusion criteria determine which forms and durations of withdrawal count. Assessment methods determine how researchers identify those experiences. Recruitment determines whose experiences enter the study in the first place.
Hikikomori is also not a medical diagnosis in itself and is not always associated with a particular psychiatric condition. That makes identifying and counting it more complicated: researchers are examining a pattern of life and behavior that can arise through different combinations of personal difficulties and social pressures.
What Changed During the Pandemic
The Italian study of 7,500 teenagers followed social behavior between 2019 and 2022, covering the period before and after pandemic restrictions. Many adolescents remained socially active. A growing subset, however, became what the researchers called Lone Wolves, with the number who never met friends doubling in the years after restrictions.
The researchers described this withdrawal as chronic, meaning persistent rather than a brief change in mood or teenage behavior. The resulting lifestyle resembled hikikomori: social separation was becoming an enduring part of everyday life.
COVID-19 restrictions made staying home normal and, for periods, necessary. Remote work, entertainment available on demand, and deliveries of food and other goods reduced the practical need to go outside. For people already experiencing social anxiety or depression, the relief of avoiding difficult encounters could become a pattern that continued beyond lockdown.
Carol Berman, a psychiatry professor practicing in New York, explained how different mental health difficulties can make leaving home frightening. She described anxiety as one possible route into withdrawal:
You could have a whole bunch of different things as a mental health patient and that could cause you to not want to go outside. Someone with a bad anxiety disorder could be afraid that if they go outside they will get a panic attack.
Berman also stressed that psychiatric patients do not present identically. Treatment needs to reflect the individual's difficulties, rather than assuming one standard approach will work for everyone.
A person afraid of having a panic attack outside may need help addressing that fear. Someone whose withdrawal accompanies depression may face a different set of barriers. The shared outcome, remaining at home and avoiding contact, can conceal very different experiences.
Where Withdrawal and Other Conditions Meet
Social anxiety disorder, major depression, autism spectrum conditions, post-traumatic stress disorder and avoidant personality disorder can occur alongside hikikomori. Clinicians face a continuing debate over whether prolonged withdrawal should be understood as a condition in its own right or as a consequence of another disorder.
Some researchers use the term secondary hikikomori when withdrawal develops as a result of another psychiatric condition. Primary hikikomori describes the alternative understanding, in which withdrawal is the central problem. Separating the two can be difficult because symptoms overlap and influence one another.
Social anxiety disorder is described as the most common psychiatric condition preceding the onset of hikikomori. Studies indicate that approximately 30 to 35 percent of withdrawn individuals experience this accompanying condition. Social anxiety involves fear surrounding interactions with other people, helping explain why conversation, appointments or workplace encounters can become obstacles.
Japan's recognition of hikikomori sits alongside its inclusion as a cultural expression of distress in DSM-5-TR, the revised psychiatric classification manual. It remains absent as a distinct diagnostic category in DSM-5 and ICD-11. These systems organize the conditions clinicians use when assessing and recording mental health problems.
Outside Japan, extreme withdrawal is consequently often categorized under depression, agoraphobia or anxiety disorders. A clinician may address the underlying diagnosis while also needing to understand the person's confinement, disrupted routines and separation from education, employment or relationships.
The spectrum approach gives clinicians another way to describe those practical difficulties. Someone who occasionally leaves home and maintains limited contact may need a different starting point from someone who rarely speaks to family and almost never leaves a bedroom. Assessment can consider accompanying conditions while also examining how withdrawal affects daily life.
How Online Therapy Reached Akira
Akira, a Japanese man aged 30, had spent six years isolating himself before taking part in a structured course of internet delivered cognitive therapy for social anxiety disorder, known as iCT-SAD. His case illustrates a treatment approach designed to reach someone for whom attending an appointment in person is itself a major barrier.
The program lasted 14 weeks. It combined modules guided by a therapist, telephone support and behavioral experiments conducted through a webcam. Akira's social anxiety scores fell from the severe range to below clinical cutoffs, meaning below the thresholds used to identify clinically concerning symptoms. He subsequently found employment at an electronics store, ending six years of seclusion.
Cognitive therapy helps people examine the thoughts and behaviors that keep anxiety going. In this program, the online modules followed the structure of therapy delivered in person. Core work covered safety behaviors, attention experiments and conversation practice.
Safety behaviors are actions someone uses to feel protected during a feared encounter. Attention experiments examine where a person's focus goes during that encounter. Conversation practice gives the person a structured opportunity to interact and then examine the experience with therapeutic support.
Video recordings were especially useful in Akira's treatment. He could review conversations to challenge distorted perceptions of how he appeared to others. Telephone calls, text messages and occasional video sessions provided contact with the therapist while allowing the initial work to happen at home.
Akira's progress offers a concrete example of how remote treatment can become a route toward participation outside the home. The approach addressed social anxiety while using online contact to make treatment accessible at the beginning.
Why Families Remain Part of Treatment
The Japanese government recommends an intervention approach with four stages: family support and initial contact, individual support, training in intermediate group situations, and trials of social participation. The sequence moves from establishing contact toward practicing involvement with other people.
Internet based treatment may fit particularly well into the second stage, individual support. A person unable to tolerate visiting a therapist's office can begin working with a professional remotely. Later stages introduce group settings and opportunities to participate more widely.
Family involvement remains essential within this approach. Relatives often provide housing, meals and protection from outside pressure, and their relationships with the withdrawn person form part of the environment in which recovery must happen.
Difficult family dynamics can also contribute to the development and continuation of hikikomori across cultures. A lack of emotional communication and a lack of empathy toward children are among the problems identified. Support therefore needs to consider both the individual and the way members of the household communicate.
The four stages give a practical shape to that work. First contact and support can begin before someone is ready for group activity or employment. The later steps allow social participation to be tried progressively, alongside attention to any anxiety, depression or other accompanying condition.
Women, Aging Parents and Life Online
Women and people in middle age now form a substantial part of the hikikomori picture. Saito's initial focus on young men has expanded as researchers document individuals who have spent decades withdrawn. Women, previously underrepresented in statistics, are increasingly recognized as changing gender norms and workplace pressures affect their lives.
Japan's 8050 problem describes one particularly difficult household situation: parents in their eighties supporting withdrawn adult children in their fifties. As those parents begin to need care themselves, they may become unable to provide the financial and practical support on which their children depend.
People living alone present another challenge. Intervention models that rely on parents or other relatives have fewer points of contact when someone is isolated in a separate home. The widening demographic profile therefore affects how support can reach people, as well as how the condition is counted.
Remote work and digital services play two roles. They can make a withdrawn lifestyle easier to sustain, while also providing possible routes into employment. Some people earn money through online work or cryptocurrency trading and achieve financial independence without physical social interaction.
Financial independence and social participation can consequently develop differently. A person may be able to support themselves online while remaining deeply withdrawn from relationships and activity outside the home. Treatment and support need to consider the person's daily functioning as well as their income.
Declining birth rates, population aging and prolonged withdrawal create concerns for future productivity and social care. The 8050 problem makes those pressures visible within individual households, where the needs of an aging parent and a dependent adult child can grow at the same time.
The picture described by April 16, 2026, is of a form of withdrawal extending across ages, genders and countries. Psychiatric classification remains debated, prevalence estimates depend on study methods, and individual treatment needs vary. Akira's experience provides one example of recovery, while family support and gradual participation remain central to Japan's recommended approach.
