Well, that's up to you... Might depend what part of the country you're in too... and if you have anyone around you who reads manga... If you live in more multi-cultural areas or near the manga and anime fans, then it might not phase people so much. However, when you're with mono-lingual, mono-cultural folk, I suppose the other would be possible... I'd rather explain something I classed as a real name from another culture than something that just seemed like a random word though.
