Tokyo is an extremely organic city.
Typical Tokyo streetscape is heavy on modern blocky buildings, like this: https://sanpoo.jp/upload/yutenji-sanpo/yutenji_106.jpg
I would argue there is no strong correlation here. A city can be walkable and ugly, lively and unwalkable, beautiful and unwalkable, beautiful but not lively...
This is mostly meant to contrast to non-walkable spaces, where to walk to a store in an American suburb often means walking in a 3 ft wide path next to 55mph traffic and the crosswalks for said road are a half mile apart, if you’re lucky. The safe paths are circuitous if they exist and the pedestrian signals, if you can get a green one, may take minutes to cycle to and give you thirty seconds to cross 6+ lanes.
