X-Seed 4000

The X-Seed 4000 was a concept megatall skyscraper designed by Martin Pascoe on behalf of the Taisei Corporation in 1995. It was intended to have a six-kilometre-wide sea base and four-kilometre height, which would have made it taller than Mount Fuji. It was intended to accommodate between 500,000 and 1 million Japanese citizens, with an internal transportation system that would have included MagLev trains.
