  We introduce twisted Fock representations of noncommutative K\"ahler
manifolds and give their explicit expressions. The twisted Fock representation
is a representation of the Heisenberg like algebra whose states are constructed
by acting creation operators on a vacuum state. "Twisted" means that creation
operators are not hermitian conjugate of annihilation operators in this
representation. In deformation quantization of K\"ahler manifolds with
separation of variables formulated by Karabegov, local complex coordinates and
partial derivatives of the K\"ahler potential with respect to coordinates
satisfy the commutation relations between the creation and annihilation
operators. Based on these relations, we construct the twisted Fock
representation of noncommutative K\"ahler manifolds and give a dictionary to
translate between the twisted Fock representations and functions on
noncommutative K\"ahler manifolds concretely.
