Kahili Airfield was located near Kahili (Kihili) on the southern coast of Bougainville
. To the east of Kagua and Buin. To the west is Tonolei Harbor. Prewar this area was a coconut plantation. The Japanese referred to this airfield as "Buin Airfield". The Allies referred to this airfield as "Kahili Airfield" or "Kahilli Airfield".

During the middle of 1942, this area was occupied by the Japanese. During late August 1982, they began construction of a 4,700' x 300' runway surfaced with crushed coral and tar. This airfield was known to the Japanese as "Buin Airfield". Allies called this airfield "Kahili Airfield". To add to the confusion, after the war, Kara (Toripoil) Airfield was and used until 1989 and was known as "Buin Airport", but was not this airfield.

World War II Pacific Theatre History
This airfield became the primary airfield supporting fighter operations over the Southern Solomons, and defense of Bougainville, until additional airfield were constructed.
Japanese code named Buin "RXP".

On April 6, 1943 during "Operation I-Go" Allied intelligence observed 114 aircraft at Kahili, when there had only been 40 observed previously. On May 13, 1943 there were 98 fighters and 32 bombers observed. On October 1, 1943 Allied reconnaissance spotted 27 Zero fighters at the airfield, including 7 Val dive bombers.

American missions against Kahili (Buin)
February 4, 1943 - September 27, 1944

Targeted by American bombers and fighters, the airfield was left unservicable and bypassed but remained occupied by the Japanese until the end of the war.

On September 9, 1945 Australian Army, 2 Corps led by Major E. C. Taylor "Buin Liaison Group" landed at Kahili to meet with Japanese representatives to arrange the surrender of the Japanese forces in the area. On September 10, 1945 "storpedoes" filled with supplies were air dropped by a RAAF Beaufort over Kahili Airfield.

During the middle of September, the Australians supervised cleanup and dumping of war materials. Bombs and munitions were collected into a pile and dumped at sea. Two Type 95 Ha Go tanks captured at the airfield were demolished with explosives later in the month by the Australians.

Since the war, this airfield was abandoned. Several aircraft wrecks remained at the location until the late 1960s.

Osamu Tagaya adds:
"The Japanese sources during the war, when they spoke of 'Buin', they were referring to what the Allies called 'Kahili'. The Japanese report that their 'Buin' was next to a river and the end of the runway faced out to sea. Both Japanese and Allied sources indicate that there was only this one airstrip until Toripoil (Allied Kara, postwar Buin) was built later."
