Japanese Notation
The prevailing notation system in Japan replaces alphabetical directional acronyms with numerical representations. Although the style may seem confusing and unorthodox at first, its basis is surprisingly intuitive. The nine possible positions of the joystick are overlaid onto a standard number pad and assigned corresponding numerical values. This single concept replaces both the Control Scheme and Motion Abbreviations of the standard American notation system. The advantage here is that numerical representations are exact about the specific input directions referenced, whereas certain alphabetical acronyms such as QCF are sometimes ambiguous, relying on definition by convention. Of course, the major disadvantage is the system's limited user base among English-speaking audiences. Both schemes have advantages and disadvantages with respect to conciseness/compression. Fortunately, it's not a difficult language to learn should the opportunity arise to communicate with foreign players.
