Google announced that three more Japanese cities "Yokohama, Sendai and Saitama' are viewable in 3D in Google Earth. You can now tour photo-realistic, 3D buildings in these cities without leaving your house -- or climbing aboard a shinkansen.
If you'd like to extend your virtual stay in Japan, you can take a tour of Tokyo, Kobe, Osaka or Kyoto, which're also available in Earth's 3D Buildings layer.
With Google Building Maker, you can create and contribute a building in as little as 10 minutes. In Japan, Building Maker is available for following cities: Fukuoka, Hiroshima, Kobe, Kyoto, Nagoya, Osaka, Saitama, Sapporo, Sendai, Tokyo and Yokohama. And if you'd like to refine your building bring it into Google SketchUp for fine-tuning.
