Tokyo is not a super dense city like New York. It has half the urban density as New York and doesn't even show up in the top 20 most-dense cities.
You also cannot put Los Angeles and Brasilia together. Brasilia has 1/8th the urban density of Los Angeles. Brasilia might as well be a suburb.
Furthermore, I am not sure how you are defining success but population and even GDP are not guaranteed measurements of a successful cities. A city can be both populous and miserable, such as Beijing, or economically insignificant and happy, such as San Luis Obispo, CA. So I would reconsider your claim... in truth, the happiest cities are among the most walkable.
