Spelling of surname

Is the spelling of his name canon? Could it also be Sato? If it is indeed spelled Sato, there is a possibily that Noriyuki is a relative of Noriko Sato.--Rodolphus (talk) 15:25, May 23, 2014 (UTC)

I've searched the web and, apparently, the presence of the macron, which marks long vowels, is important and would actually make two words completely different: kōtsū (交通, こうつう) "traffic"; kotsu (骨, こつ) "bone" or "knack". Although I'm not knowledgeable on the subject, I'd err on the side of caution, and say they are not related. --  Seth Cooper  owl post! 19:35, May 23, 2014 (UTC)
It's spelled "Sato" in the HBP game for Nintendo DS. A few years back, an editor added macrons to the articles on members of the Japanese National Quidditch Team, arguing this was the correct way to spell these characters' names. However, we defer to the spelling used in canon, even if it incorrect from a real-world perspective. I moved the articles back to their canonical forms, but I guess I missed this one.
