From the GoGoD Archives:
In January 2005 the Kansai Ki-in announced that it was introducing a new system of promotions effective from that date. It was virtually the same as the Nihon Ki-in system but with the following differences:
•Promotion to 7-dan is also possible by winning the NHK Cup, JAL Supergo, Shinjin-O, or Kansai Ki-in First Place Championship, or by reaching the last four of a world championship.
•In the number-of-career-wins category, the Kansai Ki-in First Place Championship and Samsung Cup are included as official events in place of the Ryusei and Agon-Kiriyama Cup.
•Promotions under the prize-money system are limited to 4-dan to 5-dan and below, and to just one player in each category.
•Promotions take effect on 1 April the following year for the career-wins and prize-money categories.
(For the Nihon Ki-in the titles which will earn automatic promotions are:
•To 9-dan:

Winning once: Kisei, Meijin, Honinbo, a world championship

Winning twice: Judan, Tengen, Oza, Gosei
•To 8-dan:

Challenging or being runner-up: Kisei, Meijin, Honinbo, a world championship

Winning once: Judan, Tengen, Oza, Gosei
•To 7-dan:

Challenging: Judan, Tengen, Oza, Gosei

Entering league: Kisei, Meijin, Honinbo

Winning once: Agon-Kiriyama Cup, Ryusei)
The last Kansai player to win the Oza was Yamada Kimio - it just that he wasn't a member of the Kansai Ki-in. Kansai fans are lucky - they have two outfits they can support.
