Having been lucky enough to witness, over the past decade and a half, the greatest urbanization in human history here in mainland China, and having lived in and visited many of its megacities, I must say the absence of any mainland Chinese cities from the exhibition does not do it any favours in terms of authenticity.

I'm curious as to how they came up with 38 million for Tokyo when Japan has a declining population, and only has 13 million in the Tokyo metropolis today.
