CP violation in B -> J/psi K-* decays is studied using an angular analysis in a data sample of 253 fb(-1) recorded with the Belle detector at the KEKB e(+)e(-) collider. The flavor separated measurements of the decay amplitudes indicate no evidence for direct CP violation. T-odd CP violation is studied using the asymmetries in triple product correlations, and the results are consistent with the standard model null predictions. The time-dependent angular analysis gives the following values of CP-violating parameters: sin2 phi(1)=0.24 +/- 0.31 +/- 0.05 and cos2 phi(1)=0.56 +/- 0.79 +/- 0.11.
