The city government of Kobe first proposed an airport adjacent to Port Island in 1971. At the time, government planners were seeking alternatives to the heavily congested Itami Airport: the original Kobe Airport plan called for six runways more than 3,000 m (9,843 ft) in length on a 1,100 ha (2,700 acres) facility. The mayor of Kobe, Tatsuo Miyazaki, declared his opposition to building such a large airport so close to the city, and was re-elected shortly afterward in 1973, defeating a competitor who supported the airport. Kobe businesses were still interested in the plan, however, and pressed the city government to propose a smaller facility with one 3,000 m (9,843 ft) runway. This plan was submitted to the Transport Ministry in 1982 as a competitor for the Kansai International Airport plan, which was then being supported by the Osaka and Wakayama prefectural governments. After the national government voiced its displeasure with the Kobe proposal, Kobe officially switched its support to the Kansai Airport proposal in 1984, but in 1985 decided to independently fund the construction of another airport. The construction of the airport was stalled for lack of funding until 1995, when it won national government support as a means for recovering the Kobe economy in the wake of the Great Hanshin earthquake. Despite ongoing controversy, locals continued to support the plan: in the 1997 mayoral election, the pro-airport coalition won a narrow victory over the anti-airport coalition. Construction began in September 1999 but political controversy continued: 87,000 signatures were collected in a petition to recall the mayor in 2000, and a citizen lawsuit to cancel the project was dismissed in 2004. The airport finally opened on February 16, 2006, with Japan Airlines operating the first flight and All Nippon Airways operating the first scheduled flight. Both ANA and JAL announced plans to replace portions of their widebody fleet with a larger number of mid-size aircraft, in part because of a need to fill the excess number of flight slots created by Kobe Airport's construction. The airport handled its first international business jet flight in September 2006. As part of its bankruptcy restructuring, JAL terminated all services out of Kobe and closed its office on June 1, 2010, in response to which Skymark Airlines announced a major expansion at the airport. ANA also cut back services following the airport's opening. Skymark is currently the dominant carrier at Kobe carrying approximately two-thirds of its passengers. In 2013, Kobe mayor Tatsuo Yada endorsed a proposal to consolidate the management of the three Kansai region airports by adding Kobe Airport to the planned sale in 2014 of operating concessions at Itami and Kansai. Kobe was already the most indebted municipality in Japan with debts of over ¥3 trillion after the Great Hanshin earthquake, and this project's cost (estimated at over ¥300 billion, or US$3 billion) has made it very controversial. Supporters argue that the third airport can mean increased competition and lower airfares. People in the surrounding regions (Shikoku, Awaji Island etc.) can now have a closer airport while access to Kansai may be limited. Since the ferry from Tokushima to Kansai International Airport was discontinued, travellers have had to rely on alternate means of transportation including a bus to Kansai Airport, which takes an hour longer, or to use the local Tokushima Airport, which is limited in schedules. On April 1, 2018, Kansai Airports Kobe founded by Orix, Vinci Airports, and Kansai Airports took over the operation of Kobe Airport. April 18, 2025, marked the opening of the international terminal, with flights to international destinations being classified as charters as of that month. Korean Air, VietJet Air and Starlux Airlines have expressed interest to operate international flights to Kobe when the restriction is loosened.
