Martial arts writer Takao Nakaya claims that this dan system was first applied to martial arts in Japan by Kanō Jigorō (1860–1938), the founder of judo, in 1883, and later introduced to other East Asian countries. In the modern Japanese martial arts, holders of dan ranks often wear a black belt; those of higher rank may also wear either red-and-white or red belts depending on the style. Dan ranks are also given for strategic board games such as go, Japanese chess ("shōgi"), and renju, as well as for other arts such as the tea ceremony ("sadō" or "chadō"), flower arrangement ("ikebana"), Japanese calligraphy ("shodō"), and Japanese archery ("Kyudo"). Today, this ranking system is part of the hallmark, landscape, and cultural "adhesive" of modern Japanese society.
