A guide to the different parts of TOKYO SKYTREE

Overview of TOKYO SKYTREE
Antenna gain tower(antenna tower) The Tower's top is a 140-meter-tall steel tower where the antenna is installed. At the very top, there is a device that reduces wind and earthquake tremors to ensure stable radio wave transmission.
Tembo Deck/ Tembo Galleria(Observation deck) The Tembo Deck is divided into three levels at heights of 340m, 345m, and 350m, and has an area that can accommodate approximately 2,000 people. The Tembo Galleria starts at a height of 445m, and you walk about 110m along a glass-enclosed corridor to Highest point, Sorakara Point, at a height of 451.2m.
Central pillar A reinforced concrete column runs through the center of the Tower, reaching a height of 375 meters. During Strong winds or earthquakes, it sways differently from the Tower's Steel framework, effectively canceling out the swaying. An Emergency Stairs is located inside.
shaft This is the central section of the tower that houses the Elevator, wiring, and piping. There is a gap of about one meter between the Central pillar and the shaft, and above 125 meters, an "oil damper" is installed between the Central pillar and the Central pillar, acting as a cushion to prevent the Central pillar from hitting the tower body.
Tower body The Tower 's main structure is made of steel frames, constructed by welding together circular Steel framework pipes. Complexly shaped Steel framework were manufactured in a factory, then stacked and welded together to erect the Tower. Approximately 37,000 unique Steel framework were used.

Elevator at TOKYO SKYTREE

The " Tembo Shuttle " Elevator connects the ground floor to the Tembo Deck in approximately 50 seconds, and the Tembo Deck to the Tembo Galleria in approximately 30 seconds. The Tembo Shuttle , which connects the ground floor to the Tembo Deck , travels at 600 meters per minute, making it one of the fastest large-capacity Elevator in the world (and the fastest in Japan) for a 40-passenger capacity Elevator.

The interiors of the four Tembo Shuttle connecting the ground floor to the Tembo Deck are designed to heighten anticipation for the Observation deck. Using Tradition materials and techniques passed down in the region, each of the four shuttles is fitted with art panels titled "Cherry Blossom Skies, " "Sumida River Skies," "Festival Sky," and "Miyakodori Skies," and the lighting is synchronized with the movement of the Elevator.

The two Tembo Shuttle connecting the Tembo Deck and the Tembo Galleria are 40-passenger capacity and have a see-through design. From these see-through Elevator, you can enjoy the views and look up at the elevator shaft from the ceiling, arriving at the Tembo Galleria in approximately 30 seconds (at a speed of 240 meters per minute) .

TOKYO SKYTREE lighting

The lighting of TOKYO SKYTREE utilizes state-of-the-art lighting equipment to achieve both beauty and energy efficiency. It is illuminated using an "all- LED " system consisting of a total of 2,362 lighting fixtures and a high-speed LED control system.

Normally, three types of lighting— "Iki" (representing the spirit and spirit nurtured in Edo), " Miyabi" (representing aesthetic sensibility), and "Nobori" (representing liveliness)—are illuminated alternately each day. In addition, special lighting may be illuminated to coincide with the season or events.

Design of TOKYO SKYTREE

From triangle to circle

The design of TOKYO SKYTREE is inspired by the gentle curves, or "sori" and " Convex curves ," found in Japanese swords and Tradition Japanese architecture. Furthermore, its base is made up of an equilateral triangle with sides of approximately 68 meters. The number "3" is chosen because, like the Kanae (tripod kettle) used in ancient Chinese rituals, it represents the fewest number of components needed for stability, allowing it to firmly support the structure even on a limited site and minimizing the impact on the surrounding area, such as creating a sense of oppression or casting shadows.
The structure extends upwards from the three vertices of an equilateral triangle at its base, connecting at a height of 50 meters above ground level, and becoming circular at a height of 315 meters. With a height-to-width ratio of approximately 9:1, it is a slender Tower that takes on various appearances depending on the viewing angle and location, making it a one-of-a-kind Tower in the world.

The Tower 's graceful curves express the "sleigh" shape of Tradition architecture.
The Tower 's exterior design expresses the " Convex curves " curve of Tradition architecture.

Color Palette

The color design of TOKYO SKYTREE is " SKYTREE White," an original color chosen to harmonize with the surrounding landscape and to reflect the design concept of "creating an urban landscape that transcends time and space: a fusion of Tradition Japanese beauty and Future design."

"SKYTREE White" is an original color based on "Aijiro," a Tradition Japanese color. "Aijiro" is the lightest shade of indigo dye, and its slightly bluish tint compared to pure white makes it stand out against the blue sky, creating a more vibrant impression.
