My favorite article about legal names is this one from the LA Times. "In Japan, Parents Play Devil’s Advocate in Naming Child : Controversy: Couple fights authorities’ ban on satanic moniker. Now the Cabinet has gotten involved." https://www.latimes.com/archives/la-xpm-1994-01-15-mn-12064-story.html https://www.latimes.com/archives/la-xpm-1994-01-15-mn-12064-... The gist is that in Japan names have to be composed of the official kanji set. A couple figured out they could name their child "Satan" but the Japanese authorities didn't like that particular combination, so the couple sued.
