Neon signs and street lights line up the narrower alleys of Ginza. And so the question is: if you take Japan's largest bank note, fold it up as small as it will go, then drop it on the ground in Ginza, will it buy the one square centimetre of land it falls on? The answer? No - Ginza is the home of that notoriously expensive cup of coffee and that even more extortionate apple! But price needn't be everything. For very little you can see a traditional kabuki play, go to Asia's largest fish market, see an Indian style temple, look at a capsule apartment building, and try out the latest Sony gadgets.
