  We study inhomogeneous chiral phases in nuclear matter using a hadronic model
with the parity doublet structure. With an extended ansatz for the dual chiral
density wave off the chiral limit, we numerically determine the phase
structure. A new type of dual chiral density wave where the condensate has
nonvanishing space average is confirmed and it comes to occupy a wide range of
low density region as the chiral invariant mass parameter is lowered.
