Tokyo Tower may no longer be the tallest structure in Japan, nor a full-fledged broadcasting tower, as Tokyo Skytree now holds that joint title. But it is still one of the most popular places for tourists to visit and an icon of the capital, attracting about 2 million visitors annually.

From the observation deck, tourists can see myriad skyscrapers below them, all neatly packed in the busy city. In the distance, when the sky is clear, Mount Fuji can be seen.

The 333-meter-tall Tokyo Tower ranks 22nd in the world's tallest towers, according to the Council on Tall Buildings and Urban Habitat. Tokyo Skytree ranks first at 634 meters.
