Charles J. Dunn was the Reader in Japanese at the School of Oriental and African Studies, University of London. He lived and traveled extensively in Japan.
"This interesting little book is invaluable for anyone researching what life was like for people in Japan before the Meiji Restoration. While it's an essential volume for a writer of historical fiction, those interested in Japan more generally will find it readable and packed with interesting tidbits of information. For example, I would recommend it for those who study traditional Japanese martial arts (i.e. kobudo)to get a better insight into the art they study through knowing the society from which it sprang." -Goodreads
