A Religious Rite Funded by a Secular State

Because the Daijosai is understood as the emperor's first performance of the annual Niiname-sai harvest rite in his new reign, it inherited that rite's postwar reclassification as a private religious act of the imperial family rather than an act of state, a reclassification that has produced real, recurring controversy precisely because a modern Japanese emperor's enthronement still involves public funds. Both of the most recent Daijosai, held for Emperor Akihito in 1990 and for Emperor Naruhito in 2019, drew formal objections and legal challenges from citizens and commentators who argued that using public money to fund a specifically religious ceremony conflicts with the postwar constitution's separation of religion from the state, a tension the government has generally managed by funding the rite through the Imperial Household budget under a legal characterization intended to distinguish it from ordinary state religious establishment, an arrangement critics continue to dispute rather than one that has been definitively settled.

The temporary shrine complex built specifically for the rite and dismantled afterward, and the fact that it is performed only once in a reign rather than repeated, both underline how unusual the ceremony is even within Japan's wider imperial ritual calendar, a single unrepeatable event around which a live and unresolved argument about the proper boundary between religion and the state continues to recur with each new reign.
