I prefer J-urban, like M-flo =P although they can be classified as pop, too. But I mostly listen to BoA (her Korean songs too), Koda Kumi and Hitomi Shimatani (although it's been a long time since she's released anything new... *sigh* -.-
Nami Tamaki. Then Masami Okui & T.M.Revolution. Oh, and Nakashima Mika!
But right now, Nami Tamaki is definetly my #1 favorite.
