Nagaoka is a lunar crater that lies to the southeast of the Mare Moscoviense, on the far side of the Moon. To the east of Nagaoka is the somewhat larger Konstantinov.

This is a moderately eroded crater formation, with the satellite crater Nagaoka W overlapping the northwestern rim. The remainder of the rim remains well-defined, although it is overlain by several tiny craterlets. The inner wall has slumped in places, forming terrace-like shelves. A few small craterlets lie within the crater interior.

Satellite craters[edit]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Nagaoka.
