This book argues that sound as it is created, transmitted, and perceived plays a key role in the constitution of space and community in contemporary Japan. The book examines how sonic practices reflect politics, aesthetics, and ethics, with transformative effects on human relations. From right-wing sound trucks to left-wing protests, from early 20th century jazz cafes to contemporary avant-garde art forms, from the sounds of U.S. military presence to exuberant performances organized in opposition, the book, rich in ethnographic detail, contributes to sensory anthropology and the anthropology of contemporary Japan.
