Itasha are cars decorated with decals and paint jobs depicting anime, game and manga characters. The word itasha, which literally means “painful car,” is derived from the kanji for itai (”painful”) and sha (”car”). The word also appears to be a reference to the Italian sportscar, also known as itasha (although the ita for Italian is spelled with katakana instead of kanji), a conventional sort of chick magnet driven by a different sort of guy.
