Motohisa Yamakage's The Essence of Shinto is a unique work in the annals of exploring Shintoism, the folk religion of ancient Japan. Unlike scholarly works that explore the religion from position of a researcher's emotional sterility, Yamakage writes from the perspective of the true believer as he is the 79th Grand Master of Yamakage Shinto and a respected and celebrated expert on Shintoism, its history and practice.
However, being that close to the subject also carries with it some inherent problems as the author finds it difficult to remain unbiased in discussing the classic religions of the western world. A well-earned mastery of Shintoism does not necessarily make one an expert in evaluating other paradigms.
Nonetheless, The Essence of Shinto is a wonderful addition to the library of any researcher who wants a readable and accessible overview of a folk religion that has played a major role in the shaping of the culture Japan. One caveat though. It is helpful, though probably not totally necessary, to have a basic understanding of Japanese culture before reading this work.
Sadly, this is the only volume written by Motohisa Yamakage that has been translated into English. His five-volume An Introduction to Shinto is available only in Japanese and it is this reviewer's hope that someday this important work will also be made accessible to Western reader. Until then, we can be grateful The Essence of Shinto fills an important niche in the Shinto library presently available.
