AU KDDI*

What is this charge?

When Japanese mobile carrier KDDI processes monthly billing for its "au" brand subscribers, the payment system combines both identifiers into the truncated descriptor "AU KDDI*" because au is the consumer-facing brand name while KDDI Corporation is the registered legal billing entity that actually charges your account. Japan's telecom billing infrastructure, particularly through credit card networks and bank payment systems, often appends both the brand and parent company name to satisfy financial identification requirements. If you hold an au mobile plan in Japan and pay roughly ¥4,000 per month, this descriptor is simply your regular monthly mobile bill appearing under KDDI's official corporate billing credentials.
