> Tokyo is absurdly gigantic, I would not suggest randomly walking it.
Tokyo is not really a big city like London, New York or Paris. It is like a bunch of smaller cities clumped together. In fact administratively, Tokyo is a prefecture, not a city.
So sure, it is huge, but you can random walk one of the "wards" like you would a smaller city. You can also walk between wards, but expect to walk a lot, and you are unlikely to make it your primary way of moving around, but I still recommend you do it at least once. Biking is also common (note: biking is done on the sidewalk there).
