Oita Airport is connected by bus to various cities throughout the prefecture. The airport is not accessible by train.
Hovercraft Oita Airport is connected to the prefectural capital,
Ōita City, by daily
hovercraft service. The hovercraft route was introduced in 1971, but discontinued in 2009 following a decline in ridership. In 2020, it was announced that hovercraft service would be reintroduced at Oita Airport with three new hovercraft. After a series of accidents during training caused a delay of more than a year from the originally scheduled start of operations, regular service began in July 2025. Whereas the route between Oita Airport and Ōita City takes about an hour by road, it takes about 35 minutes by hovercraft. ==Airlines and destinations==
