I haven't read a lot of ""real"" Japanese literature but supposedly anticlimactic endings are appreciated there. I remember Kafka on the Shore having an especially bad one which I thought was very funny, he telegraphs an ending and then suddenly the book ends before it gets there.

But I do think too much of his writing is about the narrator meeting a series of mysterious women, not paying them enough attention and then pretending it's an ineffable mystery when they leave him. My favorite of his books is Hard-boiled Wonderland, where this doesn't happen. (There's an anime called Haibane Renmei whose plot is 100% plagiarized from that book.)
