In this article, I analyze the postwar Japanese representation of colonial experiences in Manchuria, especially the case of the Kishi regime in the late 1950s. As a symbol of innovatory bureaucrat, Kishi Nobusuke carried out various experiments on the planned economy of Manchukuo, and these experiences revived in the form of the statism and developmentalism under the postwar Japanese conservative politics. I analyze the statism of the Kishi government through the process of the Security Treaty revision and hyper economic growth, and its developmentalism through the process of the Southeast Asian diplomacy and welfare state policy. And I illuminate the postwar revival of memories of the authoritarian governance in Manchukuo. It was a nostalgic rebirth of the colonial past, and is duplicated as a neo-statism and neo-nationalism in contemporary Japan.
