This volume will be the first full-length exploration in any language of the details of the history of the Japanese language written by experts in the different subfields of linguistics. Overall, while including factual and background information, the volume will focus on presenting original research of lasting value. This includes presenting the latest research on better studied topics, such as segmental phonology, accent or focus constructions, as well as both introducing areas of study which have traditionally been underrepresented, such as syntax or kanbun materials, and showing how they contribute to a fuller understanding of all of the history of Japanese.
