Japanese store mascot help!?

So, some years ago I found a site with scans of a store mascot. I don't rember the name of the store, but every building in the chain had a different mascot. They were girls (at least mostly, I think) and fairly colorful. They were pretty cute. Apperently people went to the different locations of the store just for merchandise of the different mascots. Can anyone help me with the store name? (Links are even better!)
