Guinness World Records on Thursday officially recognized the 634-meter Tokyo Sky Tree as the world's tallest tower at a ceremony in the capital.
Alistair Richards, managing director of Guinness World Records, handed a certificate to Michiaki Suzuki, president of Tobu Tower Sky Tree Co., at the event.
"One of the purposes of the tower construction is to let the world learn about Japanese culture and technology, and the allure of a downtown area of Tokyo (in Sumida Ward). The recognition (by Guinness World Records) gives us great strength as we strive to meet that goal," Suzuki said.
The TV broadcasting tower is due to open to the public next May.
The 828-meter Burj Khalifa skyscraper in Dubai, in the United Arab Emirates, is recognized by Guinness World Records as the world's tallest structure.
