Artists performing concerts in similiar style to Ayu?

[noidea]

For asian concerts, I would say nearest concertwise would be Koda Kumi...but I don't like her concerts, I actually think her concerts and her songs are crap. Then there's Nana Mizuki who is reaching her peak at the moment, her concerts are becoming more and more epic, I estimate the cost of her first Dome Tour(LIVE DIAMOND) of summer 2009 to be actually higher than Ayus AT09, so you might want to watch her LIVE DIAMOND concert. Her vocals are amazing and the visuals are really good as well(screen videos, 6 or 7 costumes, giant stage, water, fire, dust, lasers, props...I think Ayu inspired her very much the last years) the only thing that's bad about her concerts is that it usually has 2 "cutesy" portions instead of the one Ayu does.

Then for internationals you should check out Madonna and Mylene Farmer, both have amazing concerts similar to Ayus.(Ayu actually is a BIG Madonna fan)

Thats the artists that IMO come nearest to ayu when performing
