One thing that you will notice about the photos is how clean the streets are. Sometimes there can be a lack of dustbins which is a pain but most folks are good at taking their rubbish home.
This was unlike the area that I was brought up in back in London which always had rubbish, newspapers and poo lying around. There's hardly ever any dog poo lying around in Tokyo - saw one brownie the other day which must have been the first time in 4 years or so!
