The Best J-remixes?

[Maximus]

Im currently writing a tracklist for a friend but Im stuck. He works at a nightclub and on sunday they're planning on doing a special "land of the Rising Sun" night, I dont know what that is but he asked me to look around for some very very good remixes by any artisst from Japan. I figured this is the best place to ask. So if anyone can name some for me, id be more than thankful!

I have these so far:

Do As Infinity(sp?) - AGAIN (TATSUMAKI REMIX)

and thats it lol. Im looking for more than Ayu songs, I want as much a variety as I can, mabey some Rina Aiuchi? I trust you guys' suggestions
