Highest Point: 634m

Decision of the Height of 634m

The height of the TOKYO SKYTREE was originally specified at approximately 610m in the original project. However, it was planned from the beginning to be the world's tallest free-standing broadcasting tower. After careful discussion and research on high-rise buildings that are being built around the world, it was finally decided on 634m, to become the tallest free-standing broadcasting tower in the world.

Thus, the 634m-high TOKYO SKYTREE was recognized by the Guinness World Records Company on November 17, 2011 as the tallest tower in the world.

Impressive Figures

The decision on the figure "634" for the height was based on the concept of choosing a figure that would be easy for everyone to remember with the world's tallest tower that has also become a symbol of the area.

The sound of the number "634" when read in old Japanese numbers is "mu-sa-shi", which reminds Japanese people of Musashi Province of the past, that used to cover a large area, including Tokyo, Saitama and part of Kanagawa Prefecture.

Historically speaking, the area where the TOKYO SKYTREE stands belonged to Musashi Province. From the Observation Decks, the landscape of the old Musashi Province spreads out before you and reminds visitors of the locality and history of the area lying east of Tokyo, i.e. east of old Edo.

We believe that the use of a familiar figure for the height of the TOKYO SKYTREE will make it easier for everyone to remember.
