My favorite place in Tokyo to ride my bike most days is around the Imperial Palace grounds. It is a great ride to get there and then the ride arund the inner moat is 5km. I like riding here because the only people using the path are runners and cyclists. Everyone adheres to the “keep to the left unless passing” rule. (Yes, in Japan we drive on the left). This is unique because on any other sidewalk in the city there is no adhering to the rule. People walk wherever they want and drift back and forth across the sidewalk. This makes walking difficult and cycling would be hazardous. The very reason my favorite time is between 5 and 6:30 am.
