Developed in response to the hurricane-strength wind forces and earthquakes for which the region is notorious, the tower's conical structure, with its helical steel cage, is inherently stable.
Rising out of Tokyo Bay, two kilometres offshore, the tower is capable of
housing a community of up to 60,000 people, generating its own energy and
processing its own waste.
With its own transportation system, this vertical city quarter would be self-sustaining and virtually self-sufficient.
The lower levels accommodate offices, light manufacturing and 'clean' industries such as consumer electronics. Above are apartments, while the topmost section houses communications systems and wind and solar generators, interspersed with restaurants and viewing platforms to exploit the spectacular views.
