Abstract
The purpose of this paper is to elucidate the ideological background of the “World Federal Movement” in Japan. In Japan after the Second World War, in order to find out what kind of discussion about the World Federation, Hasegawa Nyozekan (journalist, 1875-1969) and Ishibashi Tanzan's (1884-1973, journalist, prime minister) opinions on the World Federation were studied. As a result, it became clear that both of them had made enthusiastic proposals to the World Federation. Aspects common to both were first aiming to realize the World Federation, second admitting the military power monitored universally by the World Federation, and third focusing on deepening interdependence on a global scale. On these ideas, both had a positive attitude to the Post-war Constitution of Japan. Both sympathized with New Liberalism, and so were positive about World Federalism.
