How Tall Is Tokyo Skytree? Height, World Rankings & the 634 Story

Tokyo Skytree is 634 meters (2,080 feet) tall, which makes it the tallest tower in the world and the tallest structure of any kind in Japan. It reached its full height in March 2011 and opened to the public in May 2012, built primarily as a digital broadcasting tower for the Tokyo region — the observation decks and shopping complex came along as the very profitable side business.

That single number answers the search, but the rankings behind it are where it gets interesting. Skytree is the world’s tallest tower — yet it is only the third-tallest structure on Earth. Both statements are true at the same time, and the explanation is below.

The rankings, in one image — the full story below.

Tokyo Skytree vs the World’s Other Giants

Structure	Height	Location	Classification	Status
Burj Khalifa	828 m	Dubai, UAE	Building	World’s tallest building
Merdeka 118	678.9 m	Kuala Lumpur, Malaysia	Building	2nd-tallest building (completed 2023)
Tokyo Skytree	634 m	Tokyo, Japan	Tower	World’s tallest tower
Canton Tower	604 m	Guangzhou, China	Tower	2nd-tallest tower
CN Tower	553.3 m	Toronto, Canada	Tower	Tallest tower 1975–2009
Tokyo Tower	333 m	Tokyo, Japan	Tower	Japan’s tallest until Skytree

The tower lineage runs: CN Tower held the world record for over three decades, Canton Tower took it in 2009, and Tokyo Skytree claimed it when it topped out at 634 m in 2011. As of 2026, no completed tower has surpassed it.

Tallest Tower vs Tallest Building — The Honest Answer

So is Tokyo Skytree the tallest thing humans have ever built? No — and the distinction matters if you want to quote the record correctly.

The Council on Tall Buildings and Urban Habitat (CTBUH), the body that adjudicates these records, separates the two categories by usable space. A building must devote at least half of its height to occupied, usable floor area — offices, apartments, hotels. A tower is a structure where most of the height is unoccupied: a mast, a shaft, an antenna, with observation decks and equipment rooms punctuating it.

• Burj Khalifa (828 m) and Merdeka 118 (678.9 m) are full of habitable floors, so they compete as buildings — and both are taller than Skytree.
• Tokyo Skytree, Canton Tower, and the CN Tower are broadcasting and observation structures with relatively little occupied space, so they compete as towers.

The precise claim, then: Tokyo Skytree is the world’s tallest tower and the third-tallest structure of any kind, behind Burj Khalifa and Merdeka 118.

Why Exactly 634 Meters? The Musashi Story

The height was not an engineering accident — it was chosen as wordplay. In Japanese numeric reading, 6-3-4 can be read mu-sa-shi: Musashi, the name of the old province that covered present-day Tokyo, Saitama, and part of Kanagawa. The height was selected deliberately so the tower would encode the historic name of the land it stands on — and so the number would be effortless for Japanese speakers to remember.

It worked. Ask anyone in Tokyo how tall Skytree is and they will recite it back as a word, not a number.

How High Can You Actually Go?

The 634 m figure is the tip of the broadcast antenna. Visitors get impressively close to it:

Level	Height	What it is
Tembo Deck	350 m	Main three-floor observatory with 360° views
Tembo Galleria	450 m	Spiraling glass skywalk climbing the tower
Sorakara Point	451.2 m	Highest point visitors can stand

Even the lower Tembo Deck sits roughly as high as the entire Eiffel Tower (330 m), and the Galleria’s 451.2 m Sorakara Point is among the highest publicly accessible observation points in the world. For a full breakdown of what each level offers and whether the Galleria upgrade is worth it, see our Tembo Deck vs Tembo Galleria comparison.

Seeing the Height for Yourself

Statistics undersell it — from the Tembo Deck, Tokyo’s dense skyline flattens into a circuit-board sprawl, and on clear winter mornings Mount Fuji floats on the horizon about 100 km away. The elevators cover the 350 m ascent in under a minute, which is its own demonstration of the number you came here to learn. Check our tickets and combo guide for current prices and deck options, and book a dated ticket in advance to skip the longest queues at the 634-meter mark.
