I could shop for England or any other country for that matter and Waikiki and the Ala Moana Mall are really a shopper's paradise. I'm not going to list all the stores you can find there, let me just say that it's all the big names, sort of like Rodeo Drive except much bigger. And since it's as far from Tokyo to Honolulu as it is from California, the Japanese come in droves. A good exchange rate helps, too.
This place, unfortunately, is closed by now.
