The tower, which cost 65 billion on its own, has two observation decks, one at 350m and another at 450m. A trip to the lower deck will cost 2000. Visits up the tower are fully booked through July 11, said Kenji Aoyagi, a Tobu spokesman.
Six TV stations, including state-owned NHK, will use the Skytree for transmissions next year. The tower's steel frame changes from a triangle at the base to a circle at the top, and its curves and arches reflect a traditional Samurai sword, according to its owner.
Skytree is also about double the height of Japan's previous record-holder, the 333m Tokyo Tower, which opened in 1958.
The new tower looms over Tokyo's Asakusa district, previously one of the city's main entertainment areas and still home to geishas and traditional Japanese restaurants. The area also houses Senso-ji temple, a popular tourist site, famed for Kaminarimon, Thunder Gate.
"As a local I'm very pleased," Sadaharu Oh, Japan's baseball home-run record-holder, said at the opening ceremony. He grew up in Sumida City, one of Tokyo's 23 wards, and home to the tower.
