Sumo - The Reference Guide: The Soul of Japan's Ancient Martial Art: History, Ritual and the Fighting Techniques of the Dohyō and the Rise of the Yokozuna
This sumo guide was very informative. As an individual who is deeply into the international sumo communities, this book is an extremely helpful and well communicated guide for anyone looking for the how-and-why of sumo culture. It's also a great refresher for terms and everyday basics when you need to brush up for the next basho! Hakke-yoi!
