The Gate Tower Building is one of the wonderful building in Osaka. The Place of crossing highway and high-rise. In Osaka, Japan's 'Second City', space for offices is severely limited. So limited that the 16 story Gate Tower Building had to lose the 5th, 6th and 7th floors to the Hanshin highway. The elevator passes through the floors without stopping. The floors through which the highway passes consist primarily of elevators, stairways and similar things without stopping and also it has heliport on roof. The Gate Tower Building is the first building which utilizes the three-dimensional road system in Japan.
