We argue that the chiral symmetry breaking/restoration in cold, confining dense quark matter, called "quarkyonic" matter, whose presence is expected to be relevant for intermediate density region of the phase diagram. There the confining correlation among quarks survives near the Fermi surface. We will show that the strong infrared correlations induce the chiral spiral, i.e., the spatial modulation of the chiral condensate. It breaks the chiral symmetry locally but restores it globally, naturally connecting chiral symmetry broken phase and restored phase. We will also discuss the excitation spectra on the chiral spiral.
