Akihabara would probably be a good bet for the music label convoy, although Bic camrea as Gok said would most liekly have it too.

Toys R Us can be a bit hit and miss as they only have the recent lines. When I was last in Japan, the only things about were Mp3 Starscream and some left over Galaxy force at mark-down prices. At the moment, thougbI suspect that Taktoms Classics would be sparkling all over the place.

If your boss is a femme, hide any kissplayers you find, or else there is gonna be trouble!

Also travel wise, if you're only there for a day, fork out the cash for the fast train, as it can take precious time away from toy shopping when commuting.
