The aim of this study was to review the evidence for hikikomori as a new psychiatric disorder. Electronic and manual literatures searches were used to gather information on social withdrawal and hikikomori, including studies examining case definitions, epidemiology, and diagnosis. A number of recent empiric studies have emerged from Japan. However, a notable subset of cases with substantial psychopathology do not meet criteria for any existing psychiatric disorder.
