The Sakuragicho area of Yokohama seems like the only place around these parts where there has been any town planning. Even the electricity cables are underground. A century ago some of it may have been underwater, and then there was the earthquake and WW2, which both flattened much of Yokohama. A few years ago was the last time I looked down on it all from the top floor of the Landmark Tower (tall building in lower picture), when the area looked like a not particularly successful SimCity game. But maybe most of the blocks are filled in now - the curved one in the lower picture has certainly not been around long.
