Umeda Sky Building

The building was originally conceived in 1988 as the "City of Air" project, which planned to create four interconnected towers in northern Osaka. Eventually, the Japan economic bubble of the 1980s burst and brought the number of towers down to two.

The 173 m (568 ft) building was designed by Hiroshi Hara. It was constructed by Takenaka Corporation[citation needed] and was completed in 1993.

The building features a rooftop observatory, The Floating Garden Observatory, as well as an underground market that attempts to recreate the atmosphere of Osaka in the early 20th century. At the base of the towers is an urban garden with walking trails and water features.
