Reports in UK media describe a growing number of young people withdrawing from wider society and spending extended periods at home, often in bedrooms. The coverage links the trend to “hikikomori,” a phenomenon first described in Japan in the 1990s, associated with extreme social isolation and reduced participation in everyday life. While hikikomori is most commonly discussed in relation to young adults, the UK reports refer to its presence among teenagers as well. The articles say affected individuals may leave home far less frequently than usual, with some accounts describing leaving only about once a month. The reports frame the trend as a source of concern due to the potential impact on social development, mental wellbeing, and access to education or services, though specific rates, verified case counts, and causes are not established in the shared material. The outlets emphasize that hikikomori is characterized by significant withdrawal rather than ordinary shyness, and they present it as a pattern that can become prolonged when it persists.
