Kobe Airport — Kobe, Japan

Kobe Airport, given the code UKB, occupies its own artificial island built in Osaka Bay just off the city of Kobe, and opened for service in 2006 after years of debate over whether the region needed a third airport. Its construction followed the pattern set by nearby Kansai International Airport, another offshore facility, though Kobe's field is smaller and handles only domestic routes under longstanding agreements meant to divide traffic among the Kansai region's airports. A driverless rail line, the Port Liner, links the terminal to central Kobe in minutes, making it convenient for business travelers despite its limited route network. Skymark Airlines, a low-cost carrier, was founded with strong ties to this airport and remains one of its key operators. Noise agreements impose a nightly curfew, limiting flight hours more strictly than at many Japanese airports.
