Tokyo addresses explained

I am no expert but my guess at explaining what this all means is shown here. Observing these signs around the city, in combination with the most excellent, bilingual Tokyo City Map published by Kodansha, and you'll never be lost (for long at least!). As for "shibuya", and "jingumae"? I think they mean "grim area in front of Shinto Temple". Anyone care to explain the correct definition?
