not equivalent, however, to the more traditional way of "gaining professional status", i.e., being promoted from the : leagues of strong amateur players aspiring to become a professional. Rather, it is a separate system especially designed for female professionals. Qualified amateurs, regardless of gender, may apply for the "Shoreikai System" and all those who successfully "graduate" are granted kishi status; however, no woman has yet to accomplish this feat (the highest women have reached is "Shoreikai 3 dan league" by Kana Satomi and Tomoka Nishiyama), so kishi is de facto only used to refer to male shogi professionals. The JSA is the only body which can organize tournaments for professionals, e.g., the eight major tournaments in the titleholder system and other professional tournaments. In 1996, Yoshiharu Habu became the only kishi to hold seven major titles at the same time. For female professionals, both the JSA and LPSA organize tournaments, either jointly or separately. Tournaments for amateurs may be organized by the JSA and LPSA as well as local clubs, newspapers, private corporations, educational institutions or municipal governments for cities or prefectures under the guidance of the JSA or LPSA. Since the 1990s, shogi has grown in popularity outside Japan, particularly in the People's Republic of China, and especially in Shanghai. The January 2006 edition of stated that there were 120,000 shogi players in Shanghai. The spread of the game to countries where Chinese characters are not in common use, however, has been slower. In Europe , in Europe there are currently over 1,200 active players. Computer shogi Shogi has the highest game complexity of all popular chess variants. Computers have steadily improved in playing shogi since the 1970s. In 2007, champion Yoshiharu Habu estimated the strength of the 2006 world computer shogi champion Bonanza at the level of two-dan shoreikai. The JSA prohibits its professionals from playing computers in public without prior permission, with the reason of promoting shogi and monetizing the computer–human events. On October 12, 2010, after some 35 years of development, a computer finally beat a professional player, when the top ranked female champion Ichiyo Shimizu was beaten by the Akara2010 system in a game lasting just over 6 hours. On July 24, 2011, computer shogi programs Bonanza and Akara crushed the amateur team of Kosaku and Shinoda in two games. The allotted time for the amateurs was one hour and then three minutes per move.
