Ishiguro et al.

I'm currently reading Klara and the Sun, and I can't shake off the feeling that the narrator is like a good diligent schoolgirl relating in the first person the content of someone else's diary. I don't deny it might be appropriate given the context, although it's a bit frustrating when you see that the narrator declares pretty early she is writing from much later on in the story, and still it comes across so naive and unaffective.

But then I thought of Never let me go, which I DnF'd a couple years ago, and though I can't be sure I remember it correctly the tone seems very similar.

So one question is: are all his books like this? I'm thinking in particular of The Remains of the Day, which would be my next attempt.

Another question: this kind of detached, good-boy voice quality reminded me also of, say, Earthlings. Or, thinking back to a couple decades ago and less traumatic stuff, Banana Yoshimoto. Is it a japanese thing?
