  Non-Hermiticity enriches the 10-fold Altland-Zirnbauer symmetry class into
the 38-fold symmetry class, where critical behavior of the Anderson transitions
(ATs) has been extensively studied recently. Here, we propose a correspondence
of the universality classes of the ATs between Hermitian and non-Hermitian
systems. We illustrate that the critical exponents of the length scale in
non-Hermitian systems coincide with the critical exponents in the corresponding
Hermitian systems with additional chiral symmetry. A remarkable consequence of
the correspondence is superuniversality, i.e., the ATs in some different
symmetry classes of non-Hermitian systems are characterized by the same
critical exponent. In addition to the comparisons between the known critical
exponents for non-Hermitian systems and their Hermitian counterparts, we obtain
the critical exponents in symmetry classes AI, AII, AII$^{\dagger}$,
CII$^{\dagger}$, and DIII in two and three dimensions. Estimated critical
exponents are consistent with the proposed correspondence. According to the
correspondence, some of the exponents also give useful information of the
unknown critical exponents in Hermitian systems, paving a way to study the ATs
of Hermitian systems by the corresponding non-Hermitian systems.
