Former world boxing champion Yakushiji Hoe, 58, pleaded guilty on August 5 to forging adoption documents with a 29-year-old woman. The pair falsified his wife’s signature on adoption papers and submitted them to Nagoya’s Nakaku ward office in 2024. Yakushiji sought to place the woman in his family register to inherit his property while divorce talks with his wife stalled. The prosecution alleges he acted on selfish motives and undermined Japan’s family registry system.
What happened in court
Yakushiji and the 29-year-old woman both admitted to the charges at Nagoya District Court on August 5. Prosecutors alleged Yakushiji forged his wife’s name on adoption documents in 2024 and filed them with the ward office. The court heard that Yakushiji was in an extramarital relationship with the woman and wanted to place her in his household register to act as his spouse while his divorce remained unresolved.
Why the scheme unraveled
Yakushiji’s wife discovered the fraud when she learned the woman was using the Yakushiji surname. She obtained a copy of the family registry and confirmed the false adoption. This discovery exposed the entire scheme and led to criminal charges against both Yakushiji and the woman for document forgery and filing false records.
Prosecution and defense positions
Prosecutors sought a one-year prison sentence, arguing that casual criminal motivation and the attack on Japan’s family registry system warranted jail time. The defense asked for a suspended sentence, emphasizing that Yakushiji accepted responsibility and admitted guilt. Yakushiji told the court: “I swear never to think selfishly again and to have nothing to do with crime.”
What comes next
The trial concluded immediately after opening arguments on August 5. The judge will deliver the verdict on September 16. Yakushiji faces up to one year in prison if convicted, though the defense plea for a suspended sentence may influence the outcome.
Final Thoughts
Yakushiji’s guilty plea ends the trial phase quickly, with sentencing set for mid-September. His case highlights how Japan’s family registry system can be exploited in divorce disputes, and the court’s decision will signal how seriously judges treat document forgery in family law matters.
