4D Langevin model of nuclear fission based on 2-center model parametrization of nuclear shape has elucidated many important aspects of nuclear fission such as systematical and anomalous trends of mass and TKE distributions. However, the 2-center parametrizatioi should have 5-th parameter as the collective coordinate. In the present work, we have developed a 5-dimensional Langevin model for nuclear fission. This allows us to explore the full space of the coordinates wihthin the model space. This presentation gives the status of such developments.
