This paper examines the presence of lonely, isolated and impoverished older citizens in Japan's prison population, many of whom have turned to petty crime only recently and arguably lack a genuine need for corrective services. The paper offers empirical evidence drawn from a mixed-methods study that appears to confirm their compliant, ‘law-abiding’ attributes. It argues that their influx into prisons can be seen, at least in part, as citizens who are already socially excluded and stigmatised leveraging law to assert an additional risk-laden and stigmatised identity, which provides protection. The outcome is the subversion of prisons as de facto aged-care communities. This analysis resonates with an emerging body of literature that Chua and Engel (2018; 2019) have described as the ‘Identity’ school of legal-consciousness scholarship. This literature centres on empirical studies of marginalised cohorts who leverage legal structures to embrace an identity that complicates their stigma while providing desired protections.
