Takesaki duality for weights on a covariant system based on an action of a locally compact quantum group (in the sense of Kustermans and Vaes) on a von Neumann algebra is shown. In the course of proving the duality, we also introduce a notion of a Radon-Nikodym derivative with respect to an action and a weight.
