The Tokyo Tower is sitting tight right now, but it will soon face a new antenna tower that’s over twice its size. With Tokyo’s TV stations are going fully digital by 2011, they need a new tower to host all of the city’s digital radio and television signals, plus a mobile TV network. The 2,001 foot-tall concrete-and-steel tower is located in the Sumida River region and doesn’t have a name right now. But upon completion, it will soon be the world’s tallest free-standing antenna tower in the world.
