Meijin (shogi)

Meijin (名人) is one of the eight titles in Japanese professional shogi, and is the most prestigious title, along with Ryūō. The word meijin (名 mei "excellent, artful", 人 jin "person") refers to a highly skilled master of a certain field (the various arts found in traditional Japanese culture, such as the Japanese tea ceremony, go, competitive karuta, rakugo, budō).[1]

This article is about a title in shogi. For a title in go, see Meijin (go). For a title in renju, see Meijin (renju).

History
Sekine's Meijin Resignation Ceremony (将棋名人退就位式) in February 1938. Pictured sitting in the foreground are Sekine (left) and Kimura (right). (The person standing in the foreground is Kenosuke Kosuge.)

The Meijin institution started in the 17th century (Edo period), and for around 300 years (1612–1937) was a hereditary title that was passed from the reigning Meijin upon his retirement or death to another selected from three families, as deemed to be worthy.[2][3] This is known as the Lifetime Meijin system (終生名人制). In 1935, however, the Japan Shogi Association, or JSA, announced that it was abolishing the existing system of succession in favor of something more short-term and reflective of actual playing strength, known as the Real Strength Meijin system (実力名人制). In 1937, the reigning 13th Meijin Kinjiro Sekine, who had received his title under the old system and was 70 years old at the time, voluntarily gave up his title so that a new Meijin could be decided through actual tournament play. Later that year Yoshio Kimura, who was a student of Sekine, became the first Meijin to gain the title based upon actual performance by winning a tournament which included eight other top players. From 1937 to 1947, the challenger for the Meijin title was determined through tournaments involving a select number of players. Finally, in 1947, the JSA officially established the preliminary round of ranking tournaments (順位戦, jun'isen) that it currently uses.[4]

Qualifying

The Meijin title is only open to professional shogi players that are members of the Meijin tournament system. This means that unlike some other tournaments amateur players, women's professional players, and regular professionals outside of the Meijin tournament system are not allowed to compete in the tournament.[5]

The Meijin ranking tournaments are divided into five classes (A, B1, B2, C1, C2) and players compete against others within their class in a round-robin tournament throughout the year. Players who perform well during their class tournament may be promoted to the next highest class while those who perform poorly may be relegated to the next lowest one.[6] New professionals are placed at the bottom of Class C2, and the top three players of Class C2 are promoted to Class C1 for the next year. Similarly, the top two players of Classes C1, B2, B1 are promoted to the B2, B1, and A, respectively, for the next year.[6] A new professional, therefore, needs at least five years experience (five successive promotions) after their debut before they can qualify to challenge for the title of Meijin.[7]

Lifetime Meijin
Kinjirō Sekine 關根金次郞 (1868–1946), the thirteenth Lifetime Meijin and last hereditary Meijin

The first thirteen Lifetime Meijins (終生名人, shūsei meijin) were determined through succession.[8] The Lifetime Meijin as a competitive title, eisei meijin (永世名人), was established by the JSA in 1952. Players who capture the Meijin title five times (does not have to be consecutive) qualify to receive this title, but are only officially awarded it upon their retirement or death (with exceptions).[9][10]

Honorary Meijin

The Honorary Meijin (名誉名人, meiyo meijin) is another Mejin-related title. Only two have received this title, Kensosuke Kosuke in 1936 and Ichitarō Doi in 1954.[16]

Posthumous Meijin
Sankichi Sakata

A special Posthumous Meijin Meijin (追贈名人, tsuizō meijin) title was given to Sankichi Sakata in 1955 by the Japan Shogi Association after his death in 1945.[16] Sakata, a folk hero for the Osaka area, was known during his heyday for his brilliant, inventive playing but was prevented from becoming a normal Meijin by circumstances.[17] Sakata is the only person to receive this title.

Below is a list of professional players grouped by their class for the 78th Meijin league including their rank in dan as of 17 May 2019.[34] The current Meijin title holder is Masayuki Toyoshima (who, therefore, is not listed in the A class below).

Other professional players not listed here do not participate in the Meijin league and are known as Free Class (フリークラス furii kurasu) players.[35] There were 28 such players as of 1 April 2018.

Notes
  1. Although typically awarded upon retirement or death, a special exception was made for Ōyama and he was officially awarded the title while still active in special recognition of his excellent results in professional play, including being the Meijin for 13 years in a row from 1959 to 1971.
  2. 12-player preliminary tournament held and top four finishers awarded "reserve qualifier" status. Each reserve qualifier then played a 3-game half-handicap non-title match against Kimura: Kimura alternated between giving a lance handicap and no handicap. Reserve qualifiers had to win their respective 3-game match to gain the right to challenge Kimura in a 7-game match for the title. (A playoff was to be held if multiple reserve qualifiers won their respective matches.) Since Kimura won all of the half-handicap matches, no reserve qualifier was able qualify as his challenger.
  3. A tournament to determine a challenger for Kimura did start, but was cancelled while in progress due to the Second World War.
  4. The JSA unable to come to terms with Asahi Shimbun, the match's sponsor, over the prize fund. The JSA requested that the total prize fund be increased from 11,000,000 yen to 30,000,000 yen, but Asahi Shimbun refused. Negotiations were held in attempt to find a compromise, but were unsuccessful and the Asahi Shimbun's sponsorship of the match was ended.
  5. Nakahara is next with 15, followed by Kimura, Moriuchi, and Habu with eight apiece, and Tanigawa with five. Only Tanigawa, Habu and Moriuchi are still active.
  6. Nakahara is next with nine in a row (1972-1981)
  7. Habu lost the title for first time in 1997, but won it back in 2003. He lost the title again in 2004, only to recapture it for the second time in 2008. He lost title for the third time in 2011, but recaptured it again three years later in 2014.[33]
