The book is the first study on the history of one of the most powerful semi-governmental
international organizations in interwar Japan: the League of Nations Association of Japan.
Established in 1920 for the purpose of achieving the spirit of the League of Nations the
association was at the center of Japanese international cooperation and even after Japan's
withdrawal from the League itself acted vigorously as a member of the non-governmental
International Federation of League of Nations Societies. Based on extensive multi-archival
research this book explores how members of the association including both governmental and
non-governmental actors tried to address international problems such as racial equality
migration labour and population. By doing so the book reconstructs a little-known history of
Japan's international cooperation and puts it into the context of global history.
