The contributions to the open-access anthology Alterung und Pflege als kommunale Aufgabe: Deutsche und japanische Ansätze und Erfahrungen (in German) describe and analyse the challenges and strategies of ageing and elderly care in Japanese and German communities from a multidisciplinary perspective. Themes include legal frameworks, civil society engagement, caregiver shortages, technology concepts for caregiving, and the impact of the Covid-19 pandemic on the situation of elderly citizens and those in need of care. The comparison of the approaches and experiences of both countries broadens the options for actions and can provide impulses for a reorientation of existing strategies. The book is co-edited by DIJ director Franz Waldenberger, Hiroko Kudo (Chuo University), Tomoo Matsuda (Mitsubishi Research Institute), and Gerhard Naegele (TU Dortmund). It is an outcome of the project Ageing and Elderly Care in German and Japanese Communities whose results were recently presented at an international conference in Tokyo (Details). A Japanese version of the book is currently being prepared.
