Japanese Court Convicts Ex‑Bank Worker for Stealing Gold Bars, Cash Worth $2.6m
A Tokyo District Court has sentenced a former employee of Mitsubishi UFJ, one of Japan’s largest banks, to nine years’ imprisonment for stealing gold bars and cash valued at nearly $2.6 million. The court described her conduct as “heinous” and unprecedented in scale.
The convict, Yukari Yamazaki, was said to have developed a gambling addiction and fell heavily into debt through currency trading and horse betting. According to the judgment, she resorted to systematic theft from the bank’s safety deposit boxes between 2023 and 2024.
Leveraging her insider knowledge, Yamazaki disabled security protocols and unlawfully removed gold bars worth over 330 million yen (approximately $2.2 million) and more than 60 million yen in cash. The court noted that only a fraction of the stolen assets has been recovered by the bank.
In his ruling, Justice Hironobu Ono observed that although Yamazaki had no prior criminal record and had pledged to seek treatment for her gambling addiction, the gravity of her offences left the court with no option but to impose a nine‑year custodial sentence.
The case has raised wider concerns within Japan’s financial sector. Following similar incidents in other banks, the Japanese Bankers Association revised its guidelines in June 2025, expressly prohibiting the storage of cash in safety deposit boxes as part of enhanced security measures.
