At first it was just a few days of rest. Then days became weeks, weeks became months, and the front door started to feel heavier. Messages pile up but you can't think of what to say, and even a trip to the corner shop means pulling a cap low over your eyes. This is not laziness or a lack of willpower. Here is what social withdrawal (hikikomori) means, the proposed criteria and common features, why it may develop, where help is available and the very small steps you can try today.

What does hikikomori mean? #

Hikikomori is a Japanese term for severe social withdrawal. In Japan it has been observed among adolescents and young adults since around the 1970s and drew wide attention from the late 1990s. Similar cases have more recently been reported in many other countries (Kato et al., 2019). In South Korea, government documents mostly use the phrase “isolated and withdrawn youth.”

Because the Korean everyday term includes a word meaning “loner,” it can sound like a personality flaw. Withdrawal is not a defect in a person; it describes a state of being cut off from the outside world right now. This article uses the term to describe a state, not to label anyone.

Hikikomori criteria: six months and how often you go out #

Kato, Kanba and Teo (2020), who have studied hikikomori for years, proposed updated diagnostic criteria. At the center is physical isolation at home. All three of the following apply:

1. Marked social isolation at home: going out is very rare.
2. Lasting at least six months: the isolation continues without a break for six months or more. Three to six months is described as “pre-hikikomori.”
3. Problems in daily life or distress: the isolation seriously disrupts study, work or daily life, or causes distress.

The same proposal grades severity by how often a person leaves home: going out two or three days a week is mild, one day a week or less is moderate, and rarely leaving a single room is severe. Going out four or more days a week does not meet the criteria. It usually begins in adolescence or early adulthood, but onset after the age of 30 is not rare, and homemakers and older adults can meet the criteria too.

Common features: do these sound familiar? #

These are not labels. They are patterns people often describe when isolation and withdrawal go on for a long time, including words from participants in South Korea's government survey.

• Fewer activities outside: you stop going to school, work or gatherings and keep trips out short and necessary. One participant said they always wore a cap and mask even to go to the corner shop.
• Contact feels heavy: incoming calls feel frightening, and reaching out first is even harder.
• Your daily rhythm shifts: day and night swap, and more of the day goes to time online.
• Comfort at first, loneliness later: early on many feel relief at escaping painful realities outside, but as time goes on most begin to feel distress such as loneliness (Kato et al., 2020).
• Going back out gets harder: having been away for a long time can itself feel shameful, so a reason to go out becomes harder to find.

How is it different from introversion and avoiding people? #

The three can look alike from the outside, but different things sit at the center. This is a rough guide, and more than one often overlaps.

Kato et al. (2020) removed the requirement of avoiding social situations from their criteria. Many of the people they interviewed said they had few meaningful relationships and little contact with others but did not avoid people, and the authors saw this as a main difference from social anxiety disorder. Fear-driven avoidance can still sit alongside withdrawal, though. If that part is bigger, see avoiding people: signs and how to ease it. If not having anyone to reach out to feels bigger, see coping with loneliness.

Why does social withdrawal happen? #

Withdrawal rarely seems to have a single cause; several things often pile up. Hurt in relationships at school or work, giving up on a job search after things didn't work out, conflict at home and physical or mental health problems can all be triggers. South Korea's Ministry of Health and Welfare has said it aims to prevent withdrawal linked to relationship difficulties and giving up on job seeking during school and job-search years. And apart from whatever first led someone to pull back, the shame of having been away for long and the uncertainty of going back can keep the isolation going.

Not having anyone to lean on is growing too. In national statistics cited by the Ministry of Health and Welfare, the share of people with no one to talk to when they feel depressed or discouraged rose from 21.8% in 2019 to 31.6% in 2023. Based on a 2022 national youth survey and other data, the Korea Institute for Health and Social Affairs estimated that up to about 540,000 young adults may be at risk of isolation and withdrawal. Withdrawal often comes with other difficulties (Kato et al., 2020), so if your mood has been low for a long time, look at early signs of depression as well.

First small steps if you are the one withdrawing #

After a long pause, a big resolution such as “I need to go out properly now” can make your feet heavier. The goal is not to return to your old life all at once but to reconnect one very small thread to the outside.

1. Set one daily anchor: choose just a wake-up time and keep it. Opening the curtains and seeing morning light is enough.
2. One step out at a time: from your room to the living room, from the living room to the front door, from the door to the street outside. Starting at quieter times of day is fine.
3. Send one reply: instead of answering every message, send one short line to the person who feels least pressuring.
4. Do one doable thing: each day, do one thing you used to enjoy or that gives a small sense of getting something done. How small actions lift mood is explained in behavioral activation.
5. Ask one place for help: rather than doing it all alone, talk first with one person you trust, a local youth center or community mental health center, or a counselor.

Some days you'll take a step out and then retreat to your room. That isn't failure; it shows you where to start again. A short note of what you did lets you see later that you moved more than it felt.

How families can help without pressure #

Because they worry so much, families often find “How long are you going to stay like this?” coming out first. But pressure usually closes the door further. Hikikomori researchers have proposed family approaches as part of treatment (Kato et al., 2019), and South Korea's government support also offers families communication education, counseling and peer support groups.

• Start with everyday talk: keep up easy conversation about meals, the weather or things they enjoy rather than careers or going out.
• Use words without blame: instead of “Why are you like this?”, briefly share your own feelings, such as “You've seemed to be having a hard time, and I've been worried.”
• Notice small changes: when they join a meal or come to the front door, welcome it calmly rather than praising it heavily.
• Get support for yourself: families watching from the side get worn out too. It is fine to seek family counseling or a support group first.

Support services and treatment #

In December 2023, South Korea's Ministry of Health and Welfare announced a support plan for isolated and withdrawn youth, and in August 2024 it opened Youth Future Centers in four regions (Incheon, Ulsan, North Chungcheong and North Jeolla) dedicated to supporting withdrawn young adults and young family carers. At the time, the target group was adults aged 19 to 39 who had no one to lean on or who did not leave their home or room, and anyone in that age range nationwide could take an online self-check and be directed to a center or local government support. Support begins with an initial consultation and a plan, then continues with tailored programs such as peer groups, daily-life recovery activities and shared-living stays.

Locations and how to apply can change from year to year, so ask a local youth center or community mental health center what is available where you live now. Depression, anxiety or sleep problems that come along with withdrawal can be looked at by a psychiatrist or counselor. Diagnosis and medication are decided with a doctor, and counseling can help you practice rebuilding links to the outside in small steps.

How lonely have you felt lately? A loneliness check #

The CareOps loneliness check does not tell you whether you are withdrawn. It is a three-question check on how lonely you have felt in your connections with others lately. You can take it right away, with no login.

A place to start talking, even from your room #

If the first step outside still feels far away, it's fine to start by talking from where you are. CareOps Maeumi is an AI counseling app that runs sessions with approaches such as cognitive behavioral therapy (CBT) and behavioral activation, helps you choose one very small step for today, and remembers past sessions so the next one picks up where you left off.
