OMG!! I just found a hidden treasure among my photo archives! I made this post on my blog many years ago and one of the photos I took (below) that day was of Perfume! Of course I had no idea who they were but incredible that I got this shot of them, although only from behind. I just happened to be in Akiba on the day they were doing the Uchimizu event. I'm totally blown away by this find.
I googled and found another photo of Perfume at the event. I could have been in this photo if I stood around behind them longer.
Here is a link to the Akiba Report about that particular event.
