Japan votes to keep emperor succession male-only, blocking Princess Aiko from throne

Key Points:

• Japan’s Parliament approved a revision to the Imperial House Law that enshrines male-only succession for the imperial throne, maintaining a tradition that dates back around 1,500 years.
• The law now allows distant male relatives to be adopted into the imperial family to secure future male heirs, while princesses can retain their royal status after marrying commoners.
• The decision excludes Emperor Naruhito’s daughter, Princess Aiko, from succession, despite public calls for her to be allowed to inherit the throne.
• Critics argue the male-only rule accelerates the decline of the shrinking imperial family and reinforces gender inequality, while conservatives defend it as essential to the emperor’s legitimacy and tradition.
• Japan’s imperial family, stripped of governing power since 1947, remains a significant national symbol, with only a few male heirs currently eligible under the strict succession rules.
