As ubiquitous as 3D city maps might be these days, they typically don't cover Tokyo -- quite possibly due to the massive size of Japan's megalopolis. Google, however, has just taken on that daunting task. Fire up Google Maps or Google Earth and you'll now see 3D imagery for the greater Tokyo area, including landmarks like the Tokyo Sky Tree (that giant tower you see above). The expansion also brings 3D to the major population centers of Chiba, Kanagawa and Sendai. We'd advise against exploring the entirety of Google's enhanced Tokyo map unless you have a couple of hours to kill, but you can at least take a quick tour at the source link.
