All of this peeping through a small hole to watch other people being naked or have sex in a very creepy way seems to truly be a thing in Japanese literature it seems. But I do draw the line at children doing exactly that as well as animal cruelty. I don't need to read about a bunch of teenagers that think they are so much smarter than the rest of the world killing and mutilating a kitten page after page. Also, that ending was... Something. I gave him a chance but this was the last attempt at Mishima for me.
Usually I'd try and get behind the imagery and meaning in Japanese fiction but this story lost me at about page 40 l, which was about when I was done with all the sea imagery and those teenagers who very clearly aren't quite right in their head but I don't even know why.
I only finished it because I already dnfed the last Mishima book that I read but that is it for me.

WTFFFFFFFFFFFFFFFFFFFFFFFFFF

Ticks off all the Japanese tropes. Weird sex hang ups, anger at parents, animal torture, obsession with murder... I wasn’t sure at first but it slowly won me over and by the end I absolutely loved it.

The Sailor Who Fell From Grace With The Sea poses a question to me that I struggle to come out off with a definitive answer, is it possible to disagree with a book and an author so much and still praise their work?
Mishima puts so much of himself and his own ideals into his writing that it is almost impossible to separate the two, but other than disagreeing with his perspectives, I don't have anything bad to say about this novel.
The writing is quite lyrical, the imagery serves to establish a sense of reality, the characters feel like people, sometimes awful, twisted, ignorant people, but still real enough to be believable.
I wouldn't recommend the book to anyone I know, I would probably praise a million other books in Asian literature before thinking about The Sailor Who Fell From Grace With The Sea, so perhaps it is what it is, a good book that simply doesn't mean anything to me. 
If you chose to read this novel I would recommend researching about the period Mishima praises so much, the time in which Japan invaded other Asian countries, attempted to erase their culture and history, killed their people, abused their woman and children...the period a lot of Japan still praises to this day.
In conclusion, Yukio Mishima's talent seems to be minimized by his is own morals, fears and discontent. What could be a beautiful novel loses some impact due to it's highly misguided sense of righteousness, of honor.
A important piece of literature, but a rather shallow perspective of history.
