In the twenty-first century, the concept of internationalisation remains a crucial tool for understanding the dynamics of globalising processes. It draws attention to the dimensions of conscious action in inter- and trans-national phenomena, connecting globalisation with individuals’ experience of everyday life. This book explores how internationalisation is imagined, discussed and operationalised in Japan and surrounding countries. The chapters focus on educational, leisure and cultural activities, fields which are often overlooked in favour of economic and political developments in the literature. The conclusion reflects on the concept of internationalisation and assesses how it is likely to develop in Japan in future, taking into account the impact of the Great East Japan Earthquake of 2011.
