Osaka Prefectural Government Sakishima Building "Cosmo Tower"

This core landmark is a symbol befitting the international city of Osaka. The 256m-tall building is the highest in Western Japan. Its glass curtain wall reflects the blue sky, while its overall white structure makes strong use of vertical lines. An inverted, four-sided pyramid at the top of the building adds a distinctive touch to the skyline. The exterior curtain wall features floor-to-ceiling double-glazing with permeability, allowing for different impressions during the day and at night. A large, 20m-high atrium entrance space is equipped with 24 elevators and can host a number of different events.
