Motoyama No. 1 Airfield was built by the Japanese and expanded to include three intersceting runways in a triangular layout with turnaround aprons on the edges of the two north oriented runways. One runway was oriented northeast to southwest. The second runway was oriented roughly north to south with a circular turnarounds at the each end. The third runway was oriented roughly northwest to southeast with circular turnaround areas at each end.

On February 19, 1945 the U. S. Marine Corps (USMC) made an amphibious landing on the invasion beach to the southeast of the airfield. During the Battle of Iwo Jima, this location became a battlefield. The wreckage of several Japanese aircraft were abandoned and captured in the area including a Ki-46-III Dinah.
Once captured, with fighting still raging to the west and north the Americans began repairing the northeast to southwest runway. C-47 Dakotas performing air drops until completed. On February 26, 1945 the first American aircraft to land on the runway was OY-1 Sentinel piloted by Lt. Harvey Olson of Marine Observation Squadron 4. By March 2, 1945 the runway had been graded to 4,000'. On March 4, 1945 with fighting still raging nearby, a damaged B-29 "Dinah Might" 42-65280 landed with damage and low on fuel. This was the first of 2,400 emergency landings by American aircraft on Iwo Jima.
Operational, known to the Americans as "South Filed" or "Southern Airfield", or simply as Iwo Jima Airfield as it was the only operative airfield, until the others were repaired and built. A large apron area with revetments encompassed the other two runways. When completed, the northeast to southwest runway measured 6,000' x 200'. The control tower was code named "Maple". Later, a taxiway at the northern end of the runway connected to Central Field and another taxiway connected to North Field.
