Japanese Imperial House Law reforms

Overview

Japanese lawmakers and conservative groups have been debating legislative measures to protect the Imperial Family from online defamation. Proposals include shifting defamation and insult crimes against the Imperial Family from ‘complaint-based crimes’ to ‘non-complaint-based crimes,’ allowing state authorities to prosecute without a direct complaint. Critics have warned these changes could function as a de facto revival of pre-war ‘Lèse-majesté’ laws and infringe upon freedom of expression.

On October 24, 2026, revised Imperial House Law provisions officially took effect, introducing structural changes to the Imperial Family. The amendment aims to ensure a sufficient number of imperial members by allowing female royals to retain their status after marrying commoners. Additionally, the law permits the adoption of unmarried male descendants, aged 15 or older, from distant imperial lineages—specifically those from families that renounced royal status in 1947—to join the royal family and father future heirs. These adoptees must be of paternal lineage.

Despite these changes, the law maintains the tradition of male-line succession. Princess Aiko, the daughter of Emperor Naruhito, remains barred from ascending the throne, as are her future children. Under the current succession line, the throne would pass to Prince Akishino, followed by his son, Prince Hisahito. Legal scholar Akira Momochi, a proponent of the revision, suggested that having at least four adoptees would provide greater security for the succession. However, critics and scholars like Hideya Kasai argue the revisions are discriminatory based on gender and family background, as they continue to exclude female and female-line emperors. The Imperial Household Agency has stated it will prioritize privacy during the adoption process while studying implementation details, such as housing and security for female royals living with commoner husbands.
