Japan passes Imperial Household Law amendment tightening male‑line succession

Japan’s Diet approved a revision to the Imperial Household Law that seeks to preserve the imperial line by allowing female members to retain their royal status for one generation after marriage, while still excluding their spouses and children from the imperial family. The amendment also permits the adoption of male‑line descendants from former princely houses, granting them succession rights if they produce a male heir.

The change, championed by Prime Minister Sae Takahashi’s government, has sparked intense debate over gender equality and human‑rights issues. Opposition lawmaker Renho criticised the speed of the legislation and warned that it ignores growing public support for a female or matrilineal emperor. A recent poll showed 73 % of respondents favor a female emperor and 40 % support a matrilineal succession. The law is slated to take effect in October, and its passage is expected to keep the succession issue in the public eye, especially if future elections alter the governing coalition.
