Why You're Seeing "AU KDDI*" on Your Bank Statement
What Is "AU KDDI*" on My Bank Statement?
The AU KDDI* charge on your bank statement is your monthly mobile bill from au, one of Japan's largest telecommunications carriers operated by KDDI Corporation. This charge covers your au mobile phone plan, which may include voice calls, data, and any additional services you've subscribed to through au's network. The asterisk following the descriptor is standard formatting used by payment processors to separate the company code from additional billing details. If you have an active au mobile subscription in Japan, this recurring charge is completely expected and legitimate.
The descriptor AU KDDI* appears on your bank statement because KDDI Corporation, the parent company behind the au brand, registers its merchant billing name using the corporate entity rather than the consumer-facing brand alone. Payment networks and card processors use the registered merchant name, which combines the au brand prefix with the KDDI corporate identifier. This is common practice among large telecom groups in Japan, where the holding company name is incorporated into the billing descriptor for regulatory and financial tracking purposes.

Is the AU KDDI* Charge Legitimate or Fraud?
If you see AU KDDI* on your bank or credit card statement, this charge most likely comes from AU KDDI, one of Japan's largest telecommunications companies offering mobile, internet, and digital content services. This charge is generally legitimate if you or someone in your household subscribes to any AU KDDI mobile plan, AU Smart Pass, AU Hikari internet service, or any of their digital content platforms.
Common reasons you might see the AU KDDI* charge include:
- Monthly AU mobile phone or data plan billing
- AU Smart Pass or AU Smart Pass Premium subscription fees
- AU Hikari home fiber internet service charges
- Digital content purchases or subscriptions through AU's platforms
However, if you do not recognize the AU KDDI* charge and have no known relationship with AU KDDI, it is worth investigating further, as unauthorized charges do occasionally occur through compromised payment credentials.
