There have been some who have mentioned that it does not seem too busy. I live in Kiyose, which is a little way outside of downtown Tokyo. For those of you who live in Maryand, it is like living in Olney, Maryland, outside of Washington, DC. For those of you who are familiar with Vancouver, BC, it would be like living in Abbotsford, BC in relation to Vancouver, BC.
Ikebukuro (This was not one of the busier intersections)
A little over a week ago, Brian, Bette and I did take the train down to Ikebukuro. Ikebukuro would be like going down to Dupont Circle, if you lived in Maryland, and New Westminster if you lived near to Vancouver. I didn't fully get a good picture of the volume of people that were there on a Sunday evening, but needless to say there were a lot of people walking, and bicycling would be very difficult.
It was quite loud with a lot of commotion going on. I took a bit of a video, however it really was taken more for the sound rather than the visual. Have a short 10 section listen. It sounds busy, doesn't it?
I have not gone to downtown Tokyo yet, but the plan is for a trip in on Saturday, Sept. 29th. A person from the staff enjoys being tour guide and plans to take us downtown, via the train. I am looking forward to that experience.
