No.

Its a Sharingan genjutsu, stated by Obito back when it was introduced. It was even cast with the third eye (the Sharingan on Madara's forehead). As to why its not listed as a kekkei genkai, I truthfully have no clue, but I believe there is a debate on the talk page going on about it, so ask there.
