Japan has over two dozens of Servants not counting multiple variants of Okita or Oda now, while parts of the world like Sub-Saharian Africa or South America (Quetzalcoatl is from Mexico, which is geographically North America, and she's basically a space alien anyway) don't even have a single representative despite being just as important or more as wholes for the course of human history than Japan, a notoriously self-secluded country for long, ever was.
It doesn't help that except for enough characters to literally count with the fingers of a hand, all pseudo-Demi-Servants are posesssing Japanese bodies. And that Japan is the only country to get regular themed yearly events once a year, when not even more often than that.
