1. Online Complaint Information ¶

• Legitimate MUFG Bank Complaints:
• Sources: Complaints about MUFG Bank are sparse in public forums like Trustpilot or Better Business Bureau, as it primarily operates in Japan and serves institutional or high-net-worth clients. Limited retail customer complaints may relate to service issues, such as delays in international transfers or high fees for cross-border transactions.
