Ranking system used in East Asia

The dan ranking system is used by many Japanese, Okinawan, Korean, and other martial arts organizations to indicate the level of a person's ability within a given system. Used as a ranking system to quantify skill level in a specific domain, it was originally used at a Go school during the Edo period. It is now also used in most modern Japanese fine and martial arts.
