Toshiba elevators pushed its limits of technologies once again with Japan's first outdoor type observation elevator installed at Izumi Garden of Roppongi Hills. These elevators travel from the exterior of the building at a rated speed of 360 mtrs/min (According to the previous researches done by Toshiba in December 2002, this is World's Fastest Outdoor Type Observation Elevator). As the outdoor elevators are constantly exposed to varying atmospheric conditions, utmost care is been taken in terms of the technology so as to make them competely safe for passengers travelling in these elevators.
