Nyutabaru Air Base (新田原基地 (Nyūtabaru Kichi))

Nyutabaru Air Base is a Japan Air Self-Defense Force (JASDF) military aerodrome located in Shintomi, Miyazaki Prefecture, on the eastern coast of Kyushu. Established on July 17, 1940, as an Imperial Japanese Army Air Corps field, it served as a branch for the Kumagaya and Tachiarai Army Flight Schools. The Army Parachute Training Department relocated to the site from Manchukuo in October 1941. The facility was abolished following the surrender of Japan in 1945 but re-opened on December 1, 1957, as a JASDF training facility equipped with Lockheed T-33 jet trainers.

The base serves as the headquarters for the 5th Air Wing. Current tenant units include the 305th Tactical Fighter Squadron and the 23rd Flying Training Squadron, both operating F-15J aircraft. The Air Rescue Wing Nyutabaru Detachment is also stationed at the facility, utilizing UH-60J and U-125A aircraft. Historically, the base hosted the 202nd Squadron and the 301st Squadron, the latter operating F-4EJ Phantoms until its 2014 relocation. The Flight Instruction Group operated F-15DJs at the base until 2014.

The total base area is 9,135 square kilometers. Since 1980, 179.28 hectares have been designated for joint use by U.S. Forces in Japan under the U.S.–Japan Status of Forces Agreement. In 2018, the Japanese government announced plans to develop ammunition depots and parking areas at the base for U.S. military use.

In July 2021, the Ministry of Defense announced that Nyutabaru will host a squadron of JASDF F-35B aircraft. The base is situated near the Japan Maritime Self-Defense Force Kure Base, the home port of the carrier JS Kaga, which is configured for F-35B operations. International exercises at the base include the July 2023 visit of French Air and Space Force Dassault Rafale fighters during "Mission Pégase," marking the first visit by French fighter jets to Japan since World War II.
