A couple years ago I took a trip to Tokyo and it was fantastic. Top trip so far.
I bet it was crowded.  Tokyo is the most populous metropolitan area in the world
I can believe it, the Shibuya crossing was packed. I've never seen so many people in once place. What surprised me though was how quiet it was.
Shibuya was the site of a castle where the shibuya family lived during the 11th century
