In a cold, dense quark matter, there may exist the density region where the system has quark Fermi sea, but also remnant of confinement near the Fermi surface. Such a matter is called quarkyonic matter, which possesses a rigorous foundation in large Nc limit. We argue the chiral properties of quarkyonic matter including nonperturbative effects by gluon propagator supported by Gribov-Zwanziger's analyses. It is shown that nonperturbative self-consistent equations are reduced to its (1+1) dimensional version, 'tHooft model in finite density. We analyze reduced model by the use of non-Abelian bosonization. We found that chiral spiral emerges with locally violating chiral symmetry but restores it globally. The possible long range to quasi-long range order phase transition is also discussed.
