A lot of names came from locations and professions. For example, not every “miller” or “smith” is related to one another (well, any more so than every human is related to another)
Potentially no more so than anyone else who spoke that language. But yes, populations from other regions will be less related.
More to the japanese example, a 長野 (literally longfield) could be from the other end of Japan and not necessarily super genetically close (ainu, jomon, ryuukyuu, etc. admixture, and maybe ANS or others as well (not to mention Chinese, Korean, etc.)

Well, a Smith is probably more related to another Smith, or even a Schmidt or Herrera than a Nguyen.
