[6-K] MITSUBISHI UFJ FINANCIAL GROUP INC Current Report (Foreign Issuer)

Filing Explained

No offering, sale, or proceeds are disclosed; the September 18, 2026 filing adds counsel opinions to the Form F-3 record.

On September 18, 2026, the company added two counsel opinions to its Form F-3 registration record and stated that this report is incorporated into that registration statement.

The disclosed state is incorporation into the registration statement, not a reported offering, sale, or receipt of proceeds; the filing therefore adds registration documentation without establishing an immediate change in common-holder ownership or cash raised.

Exhibit 5.1 is an opinion from Japanese counsel and Exhibit 5.2 is an opinion from U.S. counsel, making them legal support documents rather than transaction reports.

The incorporation is expressly subject to later documents or reports that supersede it, so the stated effect remains limited to the registration record described in this filing.
