Awwww only one for each artist
Utada would be dominating the last 3 slots of my list
1. Ayumi Hamasaki- A Song For XX Live @ a-nation 2008
A Song for XX + Rain + Ayu's best vocals ever=best jpop performance ever
2. Perfume-Dream Fighter/ポリリズムlive @ Ontama Carnival 2009
Ok so maybe they are'nt singing but the insanely perfect choreography more than makes up for it IMO. Makes you want to get up and dance along
3. Utada Hikaru-Passion live @ Utada United 2006
Possibly the greatest opening of a concert ever
4. Koda Kumi Moon Crying live @ Kingdom Tour
So perfect it almost sounds like the studio version
5. alan - 幸せの鐘 + 懐かしい未来~longing future~ @ RED RIBBON LIVE 09[/B]
I just picked this because it was kinda boring but really beautiful...
