This collection brings together cutting-edge work by established and emerging scholars focusing on key societies in the East Asian region: China, Taiwan, Hong Kong, Japan, North and South Korea, Mongolia and Vietnam. This scope enables the collection to reflect on the nature of the transformations in constructions of sexuality in highly developed, developing and emerging societies and economies. Both Japan and China have established traditions of ‘sexuality’ studies reflecting longstanding indigenous understandings of sex as well as more recent developments which interface with Euro-American medical and psychological understandings. Authors reflect upon the complex colonial and economic interactions and cultural flows which have affected the East Asian region over the last two centuries. They trace local flows of ideas instead of defaulting to Euro-American paradigms for sexuality studies. Through looking at regional and global exchanges of ideas about sexuality, this volume adds considerably to our understanding of the East Asian region and contributes to wider discussions of social transformation, modernisation and globalisation. It will be essential reading in undergraduate and graduate programs in sexuality studies, gender studies, women’s studies and masculinity studies, as well as in anthropology, sociology, history, cultural studies, area studies and health sciences.
