Japan's unpopular revision of Imperial law that reinforces male-only succession takes effect
Japan's revised Imperial House Law took effect Saturday. It aims to address the shrinking number of imperial family members while keeping succession male-only.
- 15 is the minimum age for male adoptees from former royal branches.
- Five single princesses can now choose to stay royal after marrying commoners.
- Husbands and children of princesses do not receive royal status.
- 4 of 11 branch families that left royal status in 1947 remain.
Why it matters: The line of succession runs through Akishino, then Prince Hisahito, 20. The law bars Aiko, 24, and any children she may have.
- Remaining branch families split from Naruhito's line about 600 years ago.
- No adoption candidate has come forward so far.
