Onizuka is a small lunar impact crater that lies within the inner ring of the Apollo impact basin. The central portion of Apollo has been covered by dark basaltic-lava, and Onizuka lies at the southern edge of this plain. To the southeast of Onizuka is the Borman crater, and to the west-southwest is Chaffee crater.
Onizuka is a circular, bowl-shaped crater with a sharp edge. The inner walls are simple slopes down to the interior floor, although piles of talus lie at the base of some sections of the wall. There is a small central peak at the mid-point of the interior floor. A fine groove in the surface begins at the northern rim of Onizuka and leads away across the floor of Apollo to the east.
