The Japanese Taisei Corporation is planning to build world's tallest building, which is futuristically-named X-Seed 4000, Inhabitat.com reported.

If it ever gets built in Tokyo, X-Seed 4000 will tower above the city with its planned 13,000 ft structure.

The mountain-like X-Seed 4000 represents a utopian eco-vision for a self-contained high-rise city in the Tokyo harbour - powered mainly by solar energy. Aesthetically inspired by nearby Mount Fuji, the behemoth building would measure 13,123 feet tall with a 6 square-kilometre footprint, and could accommodate five hundred thousand to one million inhabitants.

Designed by Taisei Construction Corporation as an "intelligent building," the X-Seed 4000 would maintain light, temperature, and air pressure in response to changing external weather conditions.

Unlike conventional skyscrapers, the X-Seed 4000 would be required to actively protect its occupants from considerable air pressure gradations and weather fluctuations along its massive elevation.

Its design calls for the use of solar power to maintain internal environmental conditions. Some estimate that the cost to construct the X-Seed 4000 structure may be somewhere between USD 300-900 B.
