Y'all already know I'm in the market for a new camera, and
Kitamura Camera is the place to hit up. Big name electronic stores like Deo Deo, Best Denki, and Yamada Denki have a decent selection of shooters but Kitamura has the really good shit. There you'll find Canon Powershot S95s, EOS 60Ds, Panasonic Lumixes and other high end stuff you'll never see at a big box store.
Murasaki Sports used to be the spot to get Nike SBs, but their supply has dried up and I don't suspect they're getting any more. Still, the place has a decent shoe selection (if you wear a size 10 or below that is), an extensive Nixon watch lineup, and plenty of other swim and skate wear. I've contemplated getting a skateboard from here many a time, but thought the one I have back home would get jealous and pouty.
