I went to Tokyo ten or so years ago. My sense was that it was quite like London in terms of layout and parks, but with all the ****s removed. And yes, the trains are utterly incredible.
yea i've not been yet but its the flights that are the really costly part, like you say, the actual itinerary in japan is way cheaper than you expect i wish we had a society here where people had respect and didnt litter etc where did we go wrong?
