Tokyo is gaining greening speed.

Over the next 10 years, the Tokyo Metropolitan Government is going ahead with ambitious plans to plant a forest along Tokyo Bay, increase the number of tree-lined streets, plant grass in parks, and all the while encourage community involvement in a bid to nurture a "green movement."

Tokyo's Big Change: the 10-year plan, which was laid out in 2006, responds to growing environmental concerns worldwide and aims to boost the capital's image as it prepares to bid for the 2016 Summer Olympics.
