It took me over a year to read this book.
I'm going to set this straight for anyone interested; this isn't a novel, this isn't history, this isn't a fable:
This is a coffee-table book.
It's not very interesting, and none of the dozens of stories about samurai are engaging, at least on a meaningful level. Most of the stories are little more than a few pages long, and often, as is the nature with hundreds of years old topics, there isn't much fact to go on. Ultimately, Sato's book, which attempts to realistically and factually explore who the Samurai actually were, genuinely can't do so, and so instead simply repeats the stories you'll find in the earliest of Japanese writings, all of which is, in some way, more fable than fiction, let alone truth.
It's just boring, but it's also not the kind of book it seems like it will be. This is not a history of the samurai, nor an accounting of important samurai persons; it's just a slew of very brief stories of different samurai (most of whom are probably made up) that are actually the same story and with the same message repeated over and over.
I don't recommend this book to anyone, honestly. If you're interested in Samurai then find an actual history book, because this book is so confused in that it presents the blatantly fictitious along with the *relatively* factual.
Further, if you know anything about the samurai, then you know that they were mostly giant pieces of sh*t, and they operated on a scale almost indifferent to European knights. So right; the majority of heroics in this book are undoubtedly bull, because just like knights the samurai we're 99% a bunch of privilidged twats who didn't earn their position but were born into it because of a rigid class-society. So yeah; most of this book is mythology, presented poorly, and far more clearly and excitingly so in many, many other texts.
