This book has become my bible.
At first I didn't like it very much, the writing style didn't seem clumsy compared to other authors I enjoy (Iain Banks, etc), thats a result no doubt, of it having been translated, I can't imagine a translation ever comparing to the work in its original language.
The book describes the story of Hideyoshi, one of the three men that led to the unification of feudal Japan, from peasant boy, to farmer. Every chapter Hideyoshi faces a test of his character, and by his willingness to learn, his intelligence, and his resolve he manages to get the job done, maintain his honour (not an easy thing in feudal Japan), and maintain the good favour of his lord (not easy when that lord is Nobunaga).
What I found inspiring about this book is the way that Hideyoshi devotes himself entirely to every task, and the way he manages to approach the world in a fresh way, without getting disappointed. He is an amazing character. After reading this book I think the Western world accepts too little from its heroes!
Whats great as well is not the just the stories, but the way Yoshikawa presents them. On every page he uses almost throw away lines, in one chapter he asks; "In the end, isn't wisdom without strategy foolishness?", that just make you stop and gape at their profoundness, the way that they completely sum up the situation.
Hideyoshi pretty much sums up what Yoshikawa deems good in a character, even down to a touch of ruthlessness, so he might not be considered good in every sense. I think because Yoshikawa wanted to present a character with all the "right" traits, this book might not be the best historical account available, but I'll easily forgive Yoshikawa that, and more!
