Murakami's works, at least, feel quite westernised. They are filled with references to western music and other art, the protagonists generally have jobs that are also common in the west, and (not sure whether this is down to Murakami or his translator) the characters always sound very American in dialogue. Nothing about them feels particularly alien to a western reader, except the surrealism itself (and, perhaps, certain aspects of his portrayal of women that is sometimes considered problematic in the west).

He provides a portal to the west as a Japanese person would imagined it to be, akin to an otaku romanticizing japanise culture.
