A Tokyo developer took visitors up the world's tallest freestanding broadcast structure on April 17, a 634-meter (2,080-foot) tower with special technology meant to withstand earthquakes that often strike Japan.

The Tokyo Sky Tree is the world's second-tallest structure behind the 828-meter (2,717-foot) Burj Khalifa in Dubai, according to owner Tobu Tower Skytree Co.

The needle-like radio and television tower opens to the public on May 22.

Journalists given a tour on April 17 saw sweeping if hazy views of the Tokyo skyline.

It took about 50 seconds in a high-speed elevator to zip up to the lower observation deck at 350 meters (1,148 feet), and another 30 seconds to reach the higher deck at 450 meters (1,476 feet).

The Tokyo Sky Tree has a restaurant and two cafes on the observation decks, a vertigo-inducing glass floor that allows visitors to look straight down, and an emergency staircase with 2,523 steps.

The tower was constructed with extremely strong steel tubes surrounding a central concrete column that are structurally separate from each other in the tower's mid-section. In the event of an earthquake, the concrete core and steel frame are designed to offset each other to reduce the building's overall motion.

The Tokyo Sky Tree has been built to stand firm even if a magnitude 7 quake were to strike beneath the building, said Sho Toyoshima, a spokesman for Tobu Tower. He said the tower sustained no structural damage from the magnitude 9.0 quake that struck off Japan's northeastern coast last March, even as it was being built.

The tower is expected to bolster television and radio transmissions in the capital region. Owners hope it will also become a new tourist destination in Tokyo.
