title matches, culminating with the in 1988 for the modern line-up of seven. About 200 professional shogi players compete. Each year, the title holder defends the title against a challenger chosen from knockout or round matches. After the Second World War, SCAP (occupational government mainly led by US) tried to eliminate all "feudal" factors from Japanese society and shogi was included in the possible list of items to be banned along with Bushido (philosophy of samurai) and other things. The reason for banning shogi for SCAP was its exceptional character as a board game seen in the usage of captured pieces. SCAP insisted that this could lead to the idea of prisoner abuse. But Kozo Masuda, then one of the top professional shogi players, when summoned to the SCAP headquarters for an investigation, criticized such understanding of shogi and insisted that it is not shogi but western chess that potentially contains the idea of prisoner abuse because it just kills the pieces of the opponent while shogi is rather democratic for giving prisoners the chance to get back into the game. Masuda also said that chess contradicts the ideal of gender equality in western society because the king shields itself behind the queen and runs away. Masuda's assertion is said to have eventually led to the exemption of shogi from the list of items to be banned. Tournament play There are two organizations for shogi professional players in Japan: the JSA, and the , or LPSA. The JSA is the primary organization for men and women's professional shogi while the LPSA is a group of women professionals who broke away from the JSA in 2007 to establish their own independent organization. Both organize tournaments for their members and have reached an agreement to cooperate with each other to promote shogi through events and other activities. Top professional players are fairly well-paid from tournament earnings. In 2016, the highest tournament earners were Yoshiharu Habu and Akira Watanabe who earned ¥91,500,000 and ¥73,900,000. (The tenth highest earner, Kouichi Fukaura, won ¥18,490,000.) The JSA recognizes two categories of shogi professionals: , and . Sometimes kishi are addressed as , a term from Go used to distinguish kishi from other classes of players. JSA professional ranks and female professional ranks are not equivalent and each has their own promotion criteria and ranking system. In 2006, the JSA officially granted women "professional status".
