Purpose of reviewHikikomori (prolonged social withdrawal) was first described in Japan and was initially regarded as culture-bound. It is now recognized as a global mental health concern, more prevalent in urban settings and frequently comorbid with psychiatric disorders. In the post-COVID-19 era, home-centered lifestyles have become increasingly normative, prompting a reconceptualization of hikikomori beyond reduced outing frequency. Drawing on over two decades of clinical and research experience, we propose a psychodynamic (developmental and attachment-informed), transdiagnostic, and multidimensional framework and outline assessment and intervention strategies for urban digital societies.Recent findingsInternational frameworks distinguish pathological from non-pathological hikikomori based on psychological distress and functional impairment. Emerging evidence implicates attachment insecurity, early adversity, and transdiagnostic biological pathways involving inflammation, and neurodevelopmental mechanisms. Early-phase pathological hikikomori is associated with increased risk of depression and gaming disorder, with possible relevance of modern-type depression. Digital tools, including online engagement and virtual reality based interventions, may provide low-threshold gateways to reach otherwise hard-to-reach individuals.SummaryIn contemporary urban life, physical isolation per se is not necessarily pathological. Translating a biopsychosocial-cultural model integrating psychopathology and attachment into structured assessment, family-based approaches, clinical care, and digital interventions is essential to prevent long-term pathological hikikomori.
