The Sailor Who Fell from Grace with the Sea. Beautiful, short, poetic, but so blunt it's almost painful. Mishima definitely goes down as one of the greatest Japanese writers. Without spoiling it, it's about a mother who is a very successful businesswoman, her son, who is involved in a gang of 14 year olds with interesting ideologies which are mostly anti-establishment, and a sailor who is involved in a love affair with the mother, and is realising that he has not achieved anything great in his life, despite his feelings when he was younger that he was supposed to be someone. It's super short like 200 pages, but really stays with you. (Warning that it was written in the early 1900's, and although the language is fine to read, there's some inherently sexist comments that as a modern reader just makes you go hmm okay). 10/10 would absolutely recommend
