We're off to Japan in a month or so. My wife will no doubt be buying lots of ceramics, textiles, etc., our kind of thing, and we have a few days on an artists' island.

Can anyone suggest how I can get my own back, with a nice cartridge or something hifi that is scarce over here and doesn't involve going up a mountain to find it?

Apparently record shopping is pretty easy, but any suggestions for stores in Tokyo?
