The system was made by Nippon Otis Elevator, a company specialising in elevators and escalators. It was technically (and legally) not a railway, but a horizontal elevator; cars were attached to a cable that moved them, like a funicular. The cars did not have wheels; instead, they floated on a 0.2-mm layer of compressed air. This was the first use of such a system to be used in an airport, as well as the first in Japan.
