It says Tooyama Ema is a MALE mangaka? I haven't found any information to confirm this is true. Could I have a source, please?

Thank you.

I decided to see about searching myself. JP Wikipedia still lists as female. Googling, I could find no results from japanese websites that make reference to her being male.

I listed Tooyama Ema as a female (even Wiki does it) and I even edited her informations at this site. But too bad, many websites have written a rumor that involve that sentence "Recently, in 2012, it is revealed that Ema Tooyama is actually a guy" or something like that.

Yeah, seems like it was added to TV Tropes and English Wikipedia on the 18th of February, then here. Any references to her being female site those, but there's no news article or anything.

Btw, this is Tooyama Ema on the left:
