Hōfu Air Field (防府飛行場, Hōfu Hikōjō) (ICAO: RJOF) is a military aerodrome of the Japan Air Self-Defense Force Hōfu-kita Airbase (防府北基地, Hōfu-kita Kitchi).

It is located 1.1 NM (2.0 km; 1.3 mi) southwest[1] of Hōfu in the Yamaguchi Prefecture, Japan.

It was the main Royal Australian Air Force base during the early part of the occupation of Japan and was repaired by No.

From September 1947 the United States Air Force's 347th Fighter Wing (All Weather) based F-61 Black Widow night fighters at the airfield as part of the air defense of Japan, but moved shortly afterwards to Ashiya Airfield.

It was apparently placed in reserve status afterwards, the 6134th Air Base Squadron being a housekeeping unit until 31 August 1951.
