This talk uses two education reforms conducted under the first (2006–2007) and second (2012–2020) Abe Shinzō Administrations to consider the relationship between religion and law in contemporary Japan. The first was the 2006 revision of the Fundamental Law on Education; the second was the designation of “morality time” classes as a “special subject” in the public school curriculum. Both reforms received significant support from rightwing religious lobbies. But even though the reforms were not as far-reaching as these parties hoped, they represented a broader political strategy I call “didactic constitutionalism.” By literally changing the content and pedagogy of specific school subjects, this long-term strategy aims to make citizen-subjects who will finally vote to revise the US-drafted Constitution of 1947.
