They don't "have the rights for Kyaru", they paid a license fee for "Tsukematsukeru" specifically. Also, music licensing is region-specific, so they likely only paid her for use of her music in Japan, i.e. for Just Dance Wii U. So even if they were to put that song on JD2017, they'd have to either make it Japan-exclusive or re-license the song for the entire world.

But, most importantly, again, they did not license all of her songs, just that particular song.
