Since the late 1980s, representations of Japanese national identity and Japanese old age have been deconstructed. Images of the resilience of traditional cultural and social institutions are shown to have over-emphasized social and cultural homogeneity, elided social differentiation and inequality and minimized the significance of historical transformation. Key institutions of the postwar modernization project, including the patriarchal seniority system and household structure, are being transformed through globalization and feminization. This thesis focuses on the problem of representing individual and collective ageing in Japan in the context of modernization. Research is focussed on the contradictions, within essentialist representations of Japanese collective and individual identity, between socially constructed policy forms of old age and collective identities. Contemporary trends towards individualization and diversification of identities, and discourses on the ageing/information society, indicate cultural distance between an instrumentally rational administration and the life world of old people. Research explores the concept of embodiment through its significance in debates on postmodernization of the lifecourse in accordance with the structural shifts towards a postindustrial structure. This study examines representations of old age in broader social and cultural processes. Images of the social and cultural trajectory of the lifecourse draw attention to the embodiment of individual identities and ultimately generational cultures in contemporary social and cultural spaces. This research is the result of analyses of old age, which have been informed by postmodern theory. It in turn informs sociological theorizations of cultural representations of old age in contemporary societies.
