During late January 1942, Vunakanau Airfield was occupied by the Japanese when they occupied the Rabaul area. Immediately, construction began to repair and expand the runway for use as the main Japanese bomber airfield at Rabaul. During February 14-17, 1942 G4M1 Betty bombers from the 4th Kokutai arrived at Vunakanau Airfield.
During 1942-1943, Vunakanau Airfield was expanded and improvied by the Japanese. As of November 10, 1943 Vunakanau Airfield had two parallel runways 5,100' in length with taxiways and revetments on both sides, including 64 bomber and 81 fighter

Allied missions against Vunakanau Airfield
January 22, 1942 - June 2, 1944
During 1942 until the end of the war, Allied aircraft attacked Vunakanau Airfield bombing raids and low level attacks. On February 14, 1944 the remaining flyable aircraft were evacuated to Truk. Anti-aircraft defenses remained active until the end of the Pacific War.
One of the two runways was maintained until 1983, as an emergency landing strip for Rabaul. It was no longer maintained when Tokua Airfield was built.
The runways are overgrown, but still visible. Not much
of the Japanese airbase complex remains, except for
a few tracks that follow the runway and taxiways. Much
of the remaining wreckage was transported to the Kokopo
the mission were radio racks from an underground communications
center discovered in the 1970s at Malmaluan.
