Page "Sky City 1000" Paragraph 3

Land prices in Japan were the highest in the world at the time, and Kisho Kurokawa, one of Japan's most famous architects, has said that staggeringly ambitious buildings employing highly sophisticated engineering are still cheap, because companies pay 90 % of the cost for the land and only 10 % for the building.

Tokyo's only fire helicopter has even been used in simulation tests to see what the danger would be if a fire were to break out in the building.

Triple-decker high speed elevators which would be used in the building are also being designed in labs outside Tokyo.
