  We construct infrared star count models of the Galaxy applicable at faint
magnitudes. In addition to dwarfs and subdwarfs, we also take into account L
dwarfs, T dwarfs, and white dwarfs of both disk and halo. As a test case of the
models, we analyze the infrared imaging data at J and K' obtained during the
Subaru Deep Field Survey to study stellar objects. Infrared star count models
we have obtained predict that the Next Generation Space Telescope will
primarily see T dwarfs, M subdwarfs, and old halo white dwarfs at faint
magnitudes.
