Abstract: The Belle and BelleII experiments have collected a 1.4ab-1 sample of e+e- collision data at centre-of-mass energies near the Y(nS) resonances. These samples contain a large number of e+e- -> ccbar events that produce charmed mesons. We present searches of direct CP violation in several four-body decay modes. Asymmetries in the distributions of triple and quadruple moments probe for violation.
