The Umeds Sky Building is one of the city most recognizable landmarks, with his upside-down "U" shape. It consists of two 40-story towers that connect at their two uppermost stories, with bridges and an escalator crossing the wide atrium-like space in the center.
Located in the Umeda district of Kita-ku, the building was originally conceived in 1988 as the "City of Air" project, which planned to create four interconnected towers in northern Osaka. Eventually, practical considerations brought the number of towers down to two.
It is 173m tall and it has a rooftop observatory called the Floating Garden.
