The New Tokyo Tower looks more like the Blackpool Tower (another tower based on the Eiffel Tower)
Going back to Wikipedia, I'm looking at the Tallest Buildings in World History table. Even if the CN Tower is replaced as the tallest building, being in a list of buildings that includes the Great Pyramid, the Cologne Cathedral, Washington Monument, Eiffel Tower and the Empire State Building. That's a really elite group.
Considering Toronto doesn't have a lot of significant landmarks, I don't see CN Tower leaving the spotlight the same way that the Ostankino Tower has in Moscow, where it has to compete with more prominent buildings like St. Basil's Cathedral, the Kremlin, the Moscow Metro, etc.
