The Tokyo Tower of Babel is a Inspiration by the real Tokyo Tower, It would've be taller than Mount Everest and taller than X-seed 4000.
It would've been 33,000 (in? surface area?) miles and 20 kilometers in height, that means that it would be the size of Houston Texas. 
The Japanese Construction Plans were proposed by a Japanese Construction Firm for the limit of sky (?), and the certain expensive price tag, Will need to be needed to build this tower in the future, (This is not a fake tower but it was inspired by another tower with the same name but different) (?) (name inspired by the tower of babel, a fictional tower (do not start a religious argument) from the bible that was so tall it reached heaven.)
This might be completed in the far future.
