In Miyasaki prefecture of Japan there're less than 10 (but definately more than 1) people with the name 'Satou', using the kanji that means sugar; In several regions groups of people use the last name 'Katou', using the kanji that means 'deer head', 'deer sugar', and 'singing head'.

And ooh, I like this one: there are people with names of 'sasaki', using the kanji that means 'sandy sandy wood' =D hmm..also people with 'kimura' (can be pronounced 'onimura'), using the kanji 'ghost village' (~180 individuals).
