The Japanese welfare state has been characterized by various theorists based on different perspectives. Japan has limited government involvement in decommodification, and a Bismarckian-type male-breadwinner-based social security system. In a much extended version of Esping-Andersen's 1990 classification, the Aspalter's Ten Worlds Theory locates the Japanese welfare state system within the Pro-Welfare Conservative Welfare Regime. Male regular workers in large enterprises are usually well protected, while non-regular workers, mostly women, are left with a meager benefit system instead. The welfare state system in Japan is still very conservative and corporatist, and ideal-typically speaking still very much part of the East Asian Welfare Model (the Pro-Welfare Conservative Welfare Regime).
