Some ambitious Japanese architects want to change the world’s approach towards urban crowding / overpopulation in megacities like Tokyo, Mexico City and others. They think that we can live in the sky, so they hope to build a vertical city twice the height of today’s tallest building that would house, employ and entertain hundred of thousands of people.
However, I think this contruction project would not make it. Please remember that those stuff mentioned below are only my opinions.
The building, awaiting to be ‘properly’ named, is now temperorily labelled as ‘Tokyo Sky City’. The tower will weigh a whoopy 6 million ton upon completion, and would be a jaw-dropping 1 kilometres high. I wonder whether Tokyo’s soft and muddy soil would be able to hold up such a heavy structure. For your information, engineers would have to digs the depth of three Tokyo Sky City in order to reach the bed rock.
On the other hand, the building is too tall – it would reach a record-breaking height of 1,000 metres! It would be easily made as the main target of terrorist attacks. Maybe next time those terrorist do not need to kidnap peopleone by one but just get the entire structure under their control – that would make up hundred of thousands of hostages!
What happens if a fire broke out? The entire biulding would then be a chimney, where smoke starts of billow upwards, suffocating lots of people. Maybe the sprikling system would be activated, but I am sure that it would starve the entire Tokyo from water supply. The fire would then melt those claimed to be fire-resistant pillars which them brings the entire 1 km high building down. I think there would be more people waving their handkerchiefs outside the window than when 2 planes crahsed into the World Trade Centre in 9/11 at that moment.
That’s really building the IMPOSSIBLE building:
(1) Impossible for people to escape,
(2) Impossible for people to survive,
(3) Impossible to be built.
The picture below shows the impossible structure:

Eiffel Tower sure looks very small when compared to it!
No wonder the Japanese government would not want to start the construction yet!



















I am not aggre with the comments mention above,because if TOKYO SKY CITY ones completed it will solve many problem such as 1. our precious land which is covered by this uncontroled construction, 2.we also save FUEL which is burnt by people in transportation.
I agree, These arguments are a problem that needs to be carfully looked into, but they are easily fixed. the fire could not spread through the whole intire tower. That would almost be impposible unless there were explosions on each individual level. It would have to have some kind of system (not just sprinklers) to better put out a fire before it happens. The terroist thing is chance, im not saying that it can’t happen but it is the same volunable than the twin towers. yeah it would be easier to hit because of the size but same difference. It would stop land construction from growing to forests that are left. it could even make space that was covered in concrete back to grenery. It seems very efficent and is a wonderful and futuristic way to reduce over population on land and help to stay green.
This post was written four years back and I couldn’t believe that you visited it :razz: teehee. Anyway, speaking of it, I think that an act of terrorism will not be able to bring down the whole tower, so does for a blaze (if there’s good design). What really worries me now is that Japan sits on the intersection point of many moving (and subducting) tectonic plates, making the country more prone to earthquakes than any other countries. A huge structure like that will add unnecessary stress onto the fault lines, and like China’s Three Gorges Dam, may cause new fault lines to appear due to the mass of the tower.
But one optimistic news is that scientists are not developing high strength carbon nanotubes that has a strength hundreds of times stronger than the strongest steel we can manufacture today and yet many times lighter. This makes it a good construction material, but for technical reasons, will not be feasible for mass manufacturing in the near future.
Hello.pleas send for me more information and picpictures of sky city.thank you.
