A Dan is a measure of advanced rank, often used in martial arts and the board game go. It usually ranges from 1 to 10, with higher numbers indicating greater skill. In martial arts, it is used for black belts only. In go or shogi, players of 1 Dan or above can be considered "masters". Dan literally means "step" in Japanese.
Usually, the belt of a Dan martial artist will have a number of strips according to the person's rank.
