I always spelled it “futema” not futenma, am i wrong?

Pardon the interruption, but may I help?

　It is "Futenma", although occaisionally I have seen it as "Futennma". Have never seen it as "Futema", and a hiragana text search with it as that does not pull up anything. (Its a tricky one, I know!) ;-) Cheers,
