Dan (rank)
The ranking system is used by many Japanese, Okinawan, Korean, and other martial art 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. 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 call ...

Japan Shogi Association
The , or JSA, is the primary organizing body for professional shogi in Japan. The JSA sets the professional calendar, negotiates sponsorship and media promotion deals, helps organize tournaments and title matches, publishes shogi-related materials, supervises and trains apprentice professionals as well as many other activities. History For much of its early history, shogi followed an iemoto system centered around three families (schools): the , the and the . The Meijin title was hereditary and could only be held by members of these three families. These three schools were supported by the Tokugawa shogunate and thus controlled the professional shogi world up until 1868 when the Meiji Restoration began. By the time , the eighth and last head of the Itō school and the 11th Hereditary Meijin, had died in 1893, the influence of the families had decreased to such an extent that they had no real power at all. In 1921, there were three groups of professional players in the Tokyo ar ...

:tsume Shogi
or tsume (詰め) is the Japanese term for a shogi miniature problem in which the goal is to checkmate the opponent's king. Tsume problems usually present a situation that might occur in a shogi game (although unrealistic artistic tsume shogi exists), and the solver must find out how to achieve checkmate. It is similar to a mate-in-''n'' chess problem. The term tsumi (詰み) means the state of checkmate itself. The verb form is tsumu (詰む) "to checkmate". (The related term ''tsumero'' 詰めろ refers to the slightly different concept of "threatmate". See: Hisshi.) ''Tsume shogi'' problems are strictly forced mate problems with constant checks. They assume that the player is in brinkmate and that they will lose unless they can force a mate sequence with a check on every move. The situation simulates real shogi games in which the endgame is essentially a mutual mating race. Note that the concept of stalemate as in western chess does not exist in shogi as it essentially doe ...
