The purpose of the present paper is to generalize Sakai's work on
anticanonical models of rational surfaces to varieties of Fano type. We rst
prove a characterization of Fano type varieties using the singularities of anti-
canonical models. Secondly, we study the decomposition of the anticanonical
map using the KX-minimal model program.
