I read this to help contextualise The World of Genji. It was published in the 1960s, & there is the sense that it was written by an American to explain Japanese history to a largely Western audience. Some of the ideas are dated, but that can't be helped. I still found it an illuminating, useful supplementary read, especially the chapter, "The Cult of Beauty". Courtly life in the Heian-era makes 21st-century self-commodification seem quite tame.
