The complex Langevin method has been attracting much attention as a solutionto the sign problem since the method was shown to work in finite density QCD inthe deconfined phase by using the so-called gauge cooling procedure. Whether itworks also in the confined phase with light quarks is still an open question,though. In order to shed light on this question, we apply the method to thechiral Random Matrix Theory, which describes the epsilon regime of finitedensity QCD. Earlier works reported that a naive implementation of the methodfails to reproduce the known exact results and that the problem can be solvedby choosing a suitable coordinate. In this work we stick to the naiveimplementation, and show that a generalized gauge cooling procedure can be usedto avoid the problem.
