Oita (大分市 Oita-shi) is the capital city of Oita prefecture.
Despite its reputation as an out-of-the-way city, Oita has multiple points of access.
Located approximately 25 miles northeast of Beppu, Oita Airport is the main commercial airport in Oita Prefecture and has daily service to and from Tokyo, Osaka (both Kansai and Itami), Nagoya, Okinawa and a single international flight to Seoul, Korea.
Travel between the airport and surrounding cities and towns are handled by bus and hovercraft, unfortunately lacking any train access as of yet. The bus has an approximate travel time of 45 and 60 minutes to Beppu and Oita, respectively. The hovercraft trip is significantly faster, only taking 20 minutes, and deposits passengers at a landing in Oita just east of the Oita River. Access between this landing and the city's downtown takes approximately 10 minutes via taxi or bus and 25 to 30 minutes on foot.
Three JR Kyushu train lines run through Oita Station, located downtown: Nippo Honsen, Hohi Honsen and Kyudai Honsen. The Nippo Honsen could be considered Oita's main rail access line, running JR Kyushu's Sonic trains from Hakata Station and reaching as far south as Miyazaki. Sonic express trains take approximately two hours to and from Hakata Station. The Kyudai Honsen has local service running to the west and reaching as far as Saga Prefecture. Finally, the Hohi Honsen runs local and express service as far as Kumamoto City, Kumamoto Prefecture.
Oita is most easily accessed by car via the East Kyushu Expressway, a well-maintained toll highway that runs from Fukuoka and through Oita, as far as the city of Usuki. Though expensive to use the highway is undeniably swift.
Buses from virtually every major city on Kyushu have service to Oita, the main ones being the multiple highway buses that run to and from Fukuoka. Oita Bus, Oita Kotsu, Kamenoi Bus and a handful of others offer this highway service and travel time is approximately two hours, nearly identical to JR Kyushu's Sonic.
Diamond Ferry runs a daily ferry between Oita and Kobe/Osaka, making stops in Matsuyama, Ehime Prefecture and Takamatsu, Kagawa Prefecture. This service is a "sleeper ship", starting in Osaka in the late afternoon and running through the night until passengers disembark in the morning.
