Ibaraki Airport — Omitama, Japan

Ibaraki Airport, coded IBR, shares its runway with the Japan Air Self-Defense Force's Hyakuri Air Base northeast of Tokyo, offering a lower-cost alternative for travelers willing to journey somewhat further from the capital in exchange for cheaper fares and lighter congestion. Opened for civilian use in 2010, the airport has struggled at times to build a stable route network, relying heavily on budget carriers and a limited set of international connections, particularly to destinations in China, alongside domestic service to Kobe and other cities. Bus connections link IBR to central Tokyo, extending the journey considerably compared to flying from Narita or Haneda, which limits its appeal mainly to price-sensitive leisure travelers. The military co-location means fighter jet operations continue alongside civilian flights, giving the airport an unusual dual character.
