The Junni-sen or Ranking League is a tournament hosted by the newspapers Mainichi Shimbun and Asahi Shimbun in cooperation with the Japan Shogi Association, which acts as a qualifier for the Meijin-sen. The player with the best record in class A will challenge for the Meijin title.
Summary
The league consists of 5 classes A, B1, B2, C1, and C2. The top finisher of class A will become Meijin challenger. Even though the Meijin themselves do not participate in the league, their years as Meijin are counted as years in class A as well when calculating career records.
Each class normally conducts a round-robin tournament from June to March of the following year, from which the seeds of next year's league are decided. Most new professionals start their career in class C2, with some starting in Free Class instead (not participating in the league). Current rules do not allow skipping classes in promotion, which means that new players have to play for at least 5 years from their debut to challenge the Meijin.
Players can be promoted by moving up classes in the league, with their game fee earnings also increasing depending on their class. Other than revenue, players in higher classes also benefit by being exempt from certain preliminary rounds in other tournaments. However, a player can be forced to retire immediately or after a fixed time if they lose rights to participate in the league, a trait not seen in any other tournament.
Around the first third of March every year, all 5 games of class A's last round will be played on the same day, and most of the time the Meijin challenger and the 2 demotees will only be decided then. Due to the long duration of the games, this day is called "the shogi world's longest day", attracting attention outside of the shogi world as well. From 2014 onwards, with the exception of 2017, these games have all been played at the Fugetsuro restaurant in Aoi Ward, Shizuoka City, Shizuoka Prefecture. These games are analyzed live on giant boards at the JSA headquarters in Sendagaya, Tokyo, the Shogi Kaikan at Fukushima, Osaka, and the Osu Hall at Naka, Nagoya. They are also streamed live on TV and online.
From term 66, the Mainichi Shimbun and the Asahi Shimbun have cooperated to host the tournament. On even-numbered terms, Asahi will be listed as the first sponsor and on odd-numbered terms the Mainichi Shimbun will be listed first.
