The Supreme Court has ruled that the second daughter of executed Aum Shinrikyo cult founder Shoko Asahara can take possession of his cremated remains and hair, putting an end to a long-running family row over his ashes.

The ruling finalized the decisions of lower courts. The public security authority is closely monitoring how the remains will be treated once they are handed over to the 40-year-old daughter, amid concerns the ashes and hair will become objects of worship for followers of Aleph, a successor group of Aum Shinrikyo.

In a unanimous decision dated Friday, the Supreme Court dismissed appeals by Asahara's fourth daughter, 32, his widow, 62, and second son, 27, against the rulings in favor of the second daughter issued by the Tokyo Family Court in September 2020 and the Tokyo High Court in March this year.
