Why were Osaka and Tokyo chosen?

edition.cnn.com

Japan's Osaka and Tokyo ranked in top 10. In terms of many aspects, I can agree with this result, except for the fact that these cities are bothered with extreme heat during summer and relatively longer working hours. The former one would be difficult for human beings to control but the latter one can be changed by us.
I would like to expect these 2 cities will be ranked higher.
