Abstract As the oldest un-amended constitution in the world, the Constitution of Japan (COJ) challenges conventional theories in two ways. First, most constitutions undergo periodic tinkering to remain relevant. Social preferences, political balances of power, and cultural norms all change over time, and a constitution’s survival is correlated with its ability to adapt via amendments. Second, constitutions that are written under foreign occupations tend to have shorter lifespans. Imposed institutions and rights are more likely to be at odds with domestic priorities, especially when compared to constitutions that have been designed and ratified democratically. I explore whether the COJ’s survival is linked to its “nature”—its contents and historical origin—using data from over 700 constitutions since the 18th century. My analysis will highlight one distinctive feature of the COJ: it is uncommonly vague in specifying the structure and operation of government institutions. I argue that this vagueness—in contrast with the detailed enumeration of civil rights—gives political actors more leeway to alter institutions to match social needs or maximize partisan goals. In other words, the COJ has never been amended formally because its structure allows for “informal” adaptation via Supreme Court rulings or Diet legislation. I will also discuss ongoing amendment initiatives, and whether revisions being proposed today—particularly by the LDP—make the COJ more “normal” in comparative context.
