MUFG Bank Fraud: How to Report It and Stop the Money
If money left your MUFG Bank account without your permission, or you paid a scammer, contact MUFG Bank straight away and ask it to block the payment and your card. The first minutes matter most.
Do this first
- Call MUFG Bank’s official line below, or use help inside the official MUFG Bank app. Never use a number from a text, a caller or a search result.
- Give them the transaction details (amount, time, and the account or number you paid) and ask them to block your card and stop or recall the payment.
- Change your online banking password and PIN if anyone may know them. MUFG Bank will never ask for your PIN, password or a one-time code.
- Report it to the police too: see who handles cybercrime in Japan, and keep screenshots of every message and payment.

Know this about Japan

- Act on the Protection of Depositors from Counterfeit and Stolen Cards (Act No. 94 of 2005). If a stolen cash card is used at an ATM, the bank must refund withdrawals made from 30 days before you told it, provided you reported promptly, explained what happened and reported to the police; the refund can be cut to three quarters if you were careless, or to nothing if you were grossly negligent. It covers ATM withdrawals with counterfeit or stolen cards, not online banking or phishing transfers. Source
