Hakkō Ichiu: Religious Rhetoric in Imperial Japan

要旨

The wartime propaganda slogan Hakkō Ichiu 八紘一宇 (“Unify the whole world under one roof”) was loaded with historical meaning: Japan was glorifying the aggression and colonization of war by fostering a specific interpretation of the narrative about how Jimmu, the first emperor, founded the nation in State Shinto mythology. In this article, I consider this slogan as central to a religious rhetoric with nationalistic overtones and I analyze it in terms of etymology, connotation, and rhetorical devices. First, the expression Hakkō Ichiu originated in ancient East Asian cosmology, before becoming one of the rhetorical expressions of State Shinto, emphasizing the extent of the imperial reign. Second, the Nichirenist activist Tanaka Chigaku rediscovered it and gave it an expansionist connotation, fostering a syncretistic approach mixing Buddhist and Shinto features. Finally, during wartime, in official documents, lyrics, trademarks, etc., the slogan gave way to a number of graphic and monumental expressions, reinforcing its connections with militarism and ultranationalism. The most notable of these material expressions was the Hakkō Ichiu Tower, erected to commemorate the 2600th anniversary of the foundation of the nation and perpetuate the State Shinto rhetoric.
