No. As far as I know, the middle finger holds no special meaning in Japanese culture.

yeah I believe it does haven offensive meaning wherever one goes just as kirite mentioned...
I remember when watching Dragon Ball Z in Japan, Vegeta was holding a dragon ball and flicking off at someone... I don't remeber who it was nor the episode number... it was probably Goku he was flicking off at
i guess it is a habit for japanese ppl with glasses to do tat, i had a look at other characters with glasses in other animes and they do the same thing with their index finger.
