Tokyo Tower is a communications and observation tower located in Shiba Park, Minato, Tokyo, Japan. When the 90-meter antenna was bolted into place on October 14, 1958, Tokyo Tower was the tallest freestanding tower in the world, taking the title from the Eiffel Tower by 13 meters. Despite being taller than the Eiffel Tower, Tokyo Tower only weighs about 4,000 tons, 3,300 tons less than the Eiffel Tower. While other towers have since surpassed Tokyo Tower's height, the structure is still the tallest self-supporting steel structure in the world and was the tallest artificial structure in Japan until April 2010, when the new Tokyo Sky Tree became the tallest building of Japan.
The tower now broadcasts analog television, digital television, radio and digital radio. The tip of the antenna was damaged on March 11, 2011 as a result of the Tōhoku earthquake.
