Located in the heart of Tokyo is Ginza - a swanky modern area where a load of luxury fashion brands (Japanese and Western) can be found concentrated in and around the main Chuo Dori street. There are also a load of restaurants and coffee shops too to help shoppers recharge their depleted energy cells before continuing to shop or being dragged around shopping.
Folks who want to visit Ginza should go on a Saturday or Sunday afternoon where the main street is pedestrianized for a most pleasant walk. Its just sooo peaceful. Get off at Ginza station.
