Smart Airport is a service concept for use at the customs declaration gates in Japanese airports. Some 40,000,000 foreign visitors are expected to visit Japan in 2020. To handle such a high volume and reduce wait times, Smart Airport offers a range of options for getting passengers quickly through customers: application for smartphone, customs declaration terminals, and guidance boards. Also, walk-through gates with facial authentication mean that travelers do not need to stop for an interview. These processes reduce congestion in customs inspection areas and shorten traveler wait times.
