The a) and b) do not only apply to Tokyo. The top 10 cities in Japan can offer the same degree of convenience, less the "alienation from humanity to a level almost incomprehensible anywhere else in the world", which I find a very good description of the situation, by the way.

Concerning the "well maintained parks", several parts of Tokyo feel/look dirtier than many other places in the country, except maybe the southern part of Osaka.
