Quick answer
Tokyo Skytree is a broadcasting and observation tower in the Oshiage district of Sumida, standing at 634 meters — the tallest structure in Japan and the tallest tower in the world. A free audio sample is available at the top of the page.

INTRO
You are standing under the tallest structure in Japan: 634 meters. The height was chosen deliberately — 6-3-4, "mu-sa-shi" in Japanese, the old name for this region when it was Musashi Province. But the truly impressive thing is not the height. It is the earthquake engineering. Tokyo sits on one of the most seismically active regions on Earth. A standard skyscraper handles earthquakes by swaying — but at 634 meters, the top of the tower would move dangerously far. The Skytree's solution is a central concrete column from top to bottom, surrounded by a steel frame. The column and the frame are not rigidly connected. They are designed to move independently — the column one direction, the frame another — cancelling each other's motion. When the 2011 Tohoku earthquake hit mid-construction, the tower was undamaged. It was not even delayed. Stop and take in the view before moving on.
SECTION: The color
The tower is painted a color called "Skytree White" — a shade of white chosen specifically to harmonize with the traditional white walls of Tokyo's edo-era storehouses. But look again. From the ground, it is white. From the observation deck, looking down at the surrounding neighborhoods, the color shifts because of the way Tokyo's atmosphere scatters light. The engineers knew this. They designed the color to look good from the ground, not from a brochure. Look around and notice the details that make this place distinctive.
CLOSE
At night, the tower is lit in two alternating color schemes: "Iki" — a pale blue, representing the refined spirit of Edo — and "Miyabi" — a purple-gold, representing elegance. Which one you see depends on the day. 634 meters of deliberate engineering, deliberate aesthetics, deliberate color. Like everything in Tokyo. Take a moment to absorb the atmosphere before continuing. Find your way.
