People say this but are never able to offer any evidence for this claim. The fact is that Japan is much less homogeneous than white westerners tend to believe, and has liberalized immigration substantially in recent years. You’ll hear stats about the high percentage of Japanese people in Japan, but those statistics invariably refer to Japanese citizens, not ethnic Japanese.
