Semiclassical distorted wave model is developed to describe $(\pi^-,K^+)$inclusive spectra related to $\Sigma^-$-formation measured at KEK with $p_\pi=1.2$ GeV/c. The shape and magnitude of the spectrum on $^{28}$Si target aresatisfactorily reproduced by a repulsive $\Sigma$-nucleus potential, thestrength of which is of the order of 30$\sim$50 MeV. This strength is not sostrong as more than 100 MeV suggested by the estimation presented in the reportof the experiment.Comment: 6 pages, to be published in Prog. Theor. Phy
