  We perform the first study of baryons in holographic QCD with
$D4/D8/\bar{D8}$ multi-$D$ brane system in type IIA superstring theory. The
baryon is described as a chiral soliton solution in the four-dimensional meson
effective action derived from holographic QCD. We also present a brief review
of the holographic model from the viewpoints of recent hadron physics and QCD
phenomenologies.
