Abstract
Projects transforming the concept of eco-city into practices became a challenge to the Eastern countries to countermeasure with the global warming and climate change. We can be witnesses of rising number of significant eco-city models than might be a real fine model to other countries and cities that would like to change their current environmental situation. In particular Japan Government launched “Eco-model cities” program in 2008, to create model cities replicable elsewhere both in Japan and in the world.
