So, if Naomi was introduced through the book, I suppose it was the first western name to be adopted in Japan? And it is probably the only one where the association with the West has been completely lost by now. At least I think that eventhough names like Risa and Erika are now quite common as well, most people are aware of them being used in the West. Because of the better developed ways of communication and TV etc, I suppose, which weren't really there back then when Naomi was introduced. It's funny how today western people are happy, when they see a japanese person called Naomi thinking "cool, she has a western name, so it's easy to remember" and on the other hand Japanese people are wondering, when they see a foreign Naomi on TV, if that person has some japanese ancestors or something. Especially when seeing NaomiCampbell for the first time quite a few of them must have been really confused.
Well I think I'll send in some edit proposals for all these names, f.ex. for Naomi that it is supposed to have been originally introduced as a Western name, but has completely lost that image nowadays. And then you two can decided whether it would be useful to include these or not :)
