The airport opened in 1943 as an Imperial Japanese Navy base during World War II, and was a major base for kamikaze units beginning in February 1945, sending a total of 47 aircraft on suicide missions during operations such as the Battle of Okinawa.[4]
The airport is connected to various locations by bus and taxi. There is also a railway line, the Miyazaki Kūkō Line, which connects the airport with the city center of Miyazaki and northern cities of the prefecture.
On 2 October 2024, a bomb that was dropped by US Forces during World War II exploded under a taxiway, damaging the surface and causing the cancellation of more than 80 flights.[10][11]
