Well-written? Certainly not. I presume it was intended to be a bunch of scrolls by someone who prided himself for being in a society where military valour mattered over your glib, mainly for people of his extended family to learn the important principles of being a Samurai in feudal Japan. Also to be passed down as oral stories for inspiration of sorts. So yes, for a real modern book, it is pretty badly written.

Would I still recommend someone to read it? Depends. I can imagine people getting offended by its contents because modern westernised values are just different. However, at the very least, it is an interesting read.

Edit: From other reviews I've gathered that the author wasn't actually a warrior. That affects the purpose and my other presumptions, but doesn't affect the review much. Still, the purpose of the book was to save an idolised version of samurais in case the peace ever came to an end. Just keep in mind that it's written by someone who hadn't seen much of actual war directly and had been basically dismissed from service, living like a hermit. Though that's a good reason for romanticising an older era when he would've felt a greater purpose, he isn't a credible authority over how wars are pure and beautiful.

Very entertaining read. The book offers great insight on the importantness of correct beheading techniques and also perfumed hair routines. I now know to look for a husband who can do both and has a mustache.
Would read again.

This book goes way back...like approximately the year 1709 back. As such, it has some proverbial wisdom and some really dated crazy stuff.

The book involves sayings from Tsunetomo who was a Samurai to a Lord who looked down on the practice of Seppuku (disemboweling yourself with a sword) and therefore forbid his warriors to do so upon his death. This led to Tsunetomo becoming a monk and spewing his good ole days story to anyone who would listen.

These stories in Hagakure mainly involve who Seppuku'ed who. Living with honor and not fearing death is a central theme. There are some nuggets of wisdom about living a good life, but there's also some hate speech against women and talk of how best to behead a man. All advice may not be applicable to your life, but do what you will with it. For my part, my rating is on its usefulness to present day and readability (very easy).

An absolute classic! You have to abstract some lessons for the Japanese swordsmen of the past but you can really learn something for the present.

If you learn one thing from this book, it is that advice is cheap.
