When it comes to the Meiji Constitution, Ito Hirobumi - probably the most influential of all the oligarchs - concluded that only the imperial house can become the axis of the state of Japan. It is, therefore, no accident that the Meiji leadership undertook a new and even more dramatic effort to emphasize the centrality of the Emperor in the years leading up to the promulgation of the new constitution. After World War II, the Japanese Constitution was drawn up under the Allied occupation and was intended to replace Japan's previous militaristic, absolute-monarchy system with a form of liberal democracy. However, the Japanese government still hoped to maintain the Emperor's sovereignty. GHQ refused the Japanese government's draft. and MacArthur suggested three principles called the 'MacArthur Note.' The main conflict is between Japanese culture(centering on the Emperor) and American culture(centering on Christianity). Compared with the Meiji Constitution, the current Japanese Constitution was greatly influenced by Christianity. The purpose of this paper is to deal with the formation of Article 9 from the perspective of the influence of Christianity.
