Plans show that the 5,577 feet-high Sky Mile Tower will stand in Tokyo Bay with a cluster of islands at its feet, dwarfing everything else on the city's already soaring skyline.
The tower will feature a hexagonal design, which was found to be the most wind-resistant shape, with six interconnected “building legs” forming a slotted, tapered structure that should withstand imposing winds.
It will offer multi-level open-air sky decks at every 320 metres and shared public facilities including shops, restaurants, hotels, libraries, gyms and health clinics.
