It also felt to me to be weirdly concentrated in particular small areas. I spent a few weeks in various places in northern Japan which varied from "very quiet" to "tourists but not too many"; but in Tokyo, Akihabara was absolutely heaving with tourists (in a way it wasn't five years ago). And even in Tokyo just getting a little way away from the hotspots you could find beautiful but quiet places still. So I agree with the author's suggestion to go to parts of the country that aren't the tiny fraction of super-famous locations or social-media sensations.
