Did SM Entertainment sign the 'PPAP Pen-Pineapple-Apple-Pen' guy?

A strange yet addicting song by Piko Taro, "PPAP (Pen-Pineapple-Apple-Pen)" that has been going viral all around the world is bringing us yet another surprise.

Korean netizens are noticing Piko Taro's label on his Melon Chart song information page, which states that his label is SM Entertainment. 

Is this unique artist joining SM? Many suspect that SM Entertainment is simply working with Piko Taro as a promotion and distribution agency in Korea as they have close relations with Piko Taro's Japanese company, Avex. However, no official announcements have been made by the company itself.
