I'm actually confused by its inclusion, because Rashomon... is not a book. XD; The movie is two of the author's (very) short stories sort of spliced together, and I don't think either of them is long enough to publish separately.

Yup. Despite the title, Rashomon the movie's plot is actually largely taken from Akutagawa's In A Grove (which is an awesome mindfucky kind of story) and not so much from the actual short story Rashomon.

Personally, I liked In A Grove better than Rashomon but hey, it's not my list.
