Completed in 1992, the Gate Tower Building has the distinction of hosting a highway within its walls. Construction of the highway and the office building occurred simultaneously with the fifth and seventh floors of the building set aside for the highway to cut across. Traffic makes no contact with the actual building, and the delicate design blocks out the sound and vibration of the traffic so that office workers are not distracted.
Located in Osaka, the Umeda Sky Building is actually the byproduct of two interconnected skyscrapers.

The two buildings are connected with bridges and an escalator and the building is the twelfth tallest in Osaka.
