It'll probably be interesting the first few times you go. I tend to commute through Tokyo by bicycle, I can usually find something interesting if I take time and pay attention.
Oh for sure it will be interesting, I live in Canada, Japan is very different, it will be nice exploring the world that we live in. Biking must be fun in Tokyo, I love biking its so nice and good exercise as well, do you think you could rent bikes in Tokyo?
