Polluted Shibuya waterway
This polluted waterway in Shibuya runs parallel to Meiji Dori and the JR Yamanote Line towards Ebisu. I think this was the only time I've ever seen this particular stream blue -- most of the time, it's full of nasty pollutants which turn the water a disturbing rust colour. Most visitors don't notice just how many waterways there are running through the heart of Tokyo until they take the limousine bus to Narita Airport when they can be seen in abundance.
