RECOfan
Good shopping for second-hand music in this cavernous hall: all records are categorized and alphabetized for quick browsing, and prices start at ¥100.
musical equipment
For musical equipment, there's a good cluster of shops just southwest of the JR station. Take the pedestrian overpass to cross the highway.
Shibuya has copious music shopping opportunities, but expect some sticker shock as Japanese CDs often clock in at ¥3000+; imports are usually cheaper! In addition to the superstores below, also check out the miniature alternative ghetto Jinnan 11 and nearby, just past Tokyu Hands, full of tiny specialist record shops.
Fashion
Shibuya is the center of Japanese youth culture and it shows.

Harley Davidson Tokyo
Right up the hill from Tokyu Hands is a small street that branches off Center-gai, where you will find this Harley store. They offer t-shirts for people who collect Harley Davidson shirts. As of August 2009, this store has closed.
Anime & manga
Mandarake
Massive shop devoted to manga, anime, hentai, dojinshi, figurines and collectible offshoots.

Shibuya has lots and lots of interesting shopping opportunities. It's the home of the huge Tokyu conglomerate railways, department stores, hotels, housing developments, and thus practically every major store in the area has Tokyu in its name.
