Титул Дзюдан, означающий «10 дан», занимает четвертое место в ряду титулов профессионального Го Японии с призовым фондом 13.4 миллионов иен. Спонсируется газетой «Санкэй симбун».
Розыгрыш титула Дзюдан происходит аналогично другим 7-ми титулам – победитель предварительного турнира по олимпийской системе играет матч из 5-ти партий с контролем 6 часов на партию каждому участнику с обладателем титула. Однако, есть одна особенность. Участник, проигравший партию, переходит в турнир для проигравших. Окончательно победитель турнира проигравших играет с победителем турнира выигравших, таким образом выявляется претендент на титул. Первый приз составляет порядка 75 тысяч долларов США.

The Judan title is decided in a best of five match with 6 hours thinking time per person. The challenger comes from a knockout tournament with 16 participants. The 34th edition of the tournament shows the knockout tournament, so you can get an idea. These pages include all title match games and the knockout games when available. The Japanese Title Overview page shows what's available.
The Judan is the fourth most prestigeous title with a first prize of about USD 75,000,=
The Judan, which literally means “ten dan”, is in order of importance the fourth title in professional Japanese go with its top prize of 13.4 million Yen. The sponsoring newspaper is the sankei shinbun.
The Judan shares most of its structure with the other top 7 titles – winner of preliminary tournament plays a best of five final against the title holder – but it is unique in one aspect. Anyone who loses a game in the preliminary direct elimination tournament goes to a parallel tournament, the losers' section. At the end the winner of the loser's section plays the winner of the winner's section to decide who becomes the challenger.
The Judan Championship is sponsored by large daily national newspaper, the Sankei Shinbun (originally known as the Sangyo Keizai Shinbun). It is the successor to the Hayago Meijin.
Top prize is 10.6 million yen. Runner-up gets one fifth as much. Game fees are graduated not just according to the stage of the event but also according to rank.
The structure of the tournament is unusual in that it incorporates a repechage, though it has been copied several times. The purpose is to ensure that the strongest players do not suffer from an accidental loss.
The main section begins with a 16-player knockout (the Winners' Section), but the losers cross over to a parallel Losers' Section knockout. The level at which they enter depends on the level at which they were knocked out of the Winners' Section.
The winners of the two sections eventually play off to decide who challenges the title holder in a best-of-five (in Term 1, however, the play-off was a best-of-five to decide the first holder). With one exception, a player thus drops out only once he has lost two games.
The exception is the winner of the Winners' Section. If he loses the play-off against the winner of the Losers' Section, he gets no second chance.
All those who win two or more games in the main section retain their places the following year. The other eight players drop back to the qualifying stage.
The event is open to all pros from the Nihon Ki-in and the Kansai Ki-in. The preliminary stages are divided into three. First is a knockout tournament for all 1-dans to 4-dans (giving four from the Nihon Ki-in and two from the Kansai Ki-in), and then comes another knockout for the Stage 1 qualifiers and all 5-dans to 9-dans, to find 24 qualifiers for the third stage knockout, where they are joined by the eight players demoted from the main event.
In Term 1, all 9-dans (11) seeded to the main event.
Time limits are now 5 hours each but used to be 6 hours each. Komi is 5.5 points.
Judan means 10-dan (normally 9-dan is the highest rank awarded).
The Hayago Meijin (1956–1961), also sponsored by the Sankei Shinbun (then briefly known as the Sankei Jiji; the name was changed to Sankei Shinbun in 1956), was originally comprised of separate tournaments for East and West Japan, and the respective winners (meijins) were pitted against each other in a telegraph match for the overall title. This was because the Sankei Jiji had separate editions in Tokyo and Osaka.
Although Hayago means “quick go” or “lightning go”, in those days it meant games of 5 hours each played in one day, rather than the 10 hours and two days of the main title matches. The final was a best-of-three and komi was 4.5 points.
SergeiPavlov /31.05.2004 08:52/: Игорь, при компиляции русского текста по нескольким источникам надо аккуратно отслеживать общее соответствие. Например, цифра 13.4 млн иен (по-моему, так пишется, без «й») взята из одного источника и соответствует 110–120 тыс. USD. А цифра $75,000 взята из другого источника, что может быть просто соответствует другой сумме приза (другой год). Надо проверить по датам первоисточников и вообще – указывать время при указании сумм призового фонда. В течение последних 10-15 лет $1 соответствовал 100–130 иенам (грубо).
IgorNilov /31.05.2004 11:29/ : Да, это я погорячился. Это победитель получает 75 тыс. долларов. А даты в первоисточниках отстутсвуют. Ведь первоисточники, как я понимаю, формируют такие же как мы (любители Го) :)) Поэтому точность фактов пока проверить не могу.
