An emoji set from au by KDDI; a Japanese mobile phone carrier. Using black and white emoji characters from 1999, this set gained animation in the early 2000s before moving to static, high resolution designs.

In 2012, au replaced its custom designs with a new set heavily inspired by, and designed to be compatible with, emojis from NTT Docomo.

Note: Each emoji design within every pre-2010 emoji set has been mapped to its modern Unicode codepoint, despite these sets existing prior to Unicode emoji standardization.
