Ibaraki Airport is an airport in the city of Omitama, Ibaraki Prefecture, Japan. It also serves as air base for the Japan Air Self-Defense Force under the name Hyakuri Air Base. The airport was known as Hyakuri Airfield (百里飛行場, Hyakuri Hikōjō) prior to March 2010, when civil aviation operations began. The airport is located about 53 mi (85 km) north of Tokyo, and is intended to serve as a low-cost alternative to Tokyo's larger Narita and Haneda airports. Built as a result of large public investment, the airport has been criticized as being a symbol of wasteful government spending and as being unnecessary, opening with only one flight per day.
