D-Oh Grand Prix

The D-Oh Grand Prix (D王 GRAND PRIX) is an annual professional wrestling tournament hosted by the DDT Pro-Wrestling (DDT) promotion. Though DDT also runs the annual King of DDT Tournament, the D-Oh Grand Prix is different in that it is round-robin, whereas the King of DDT is a single-elimination tournament. Like the King of DDT however, the winner of the tournament receives a shot at the KO-D Openweight Championship.

History
The tournament was created by DDT producer Danshoku Dino in August 2017 and later confirmed in November.

After the first edition was held in January 2018, the second edition had to be held in December 2018 while retaining the name "D-Oh Grand Prix 2019". This offset between the tournament title and the year it was actually held persisted until 2021 where the tournament (held between November and December 2021) was entitled "D-Oh Grand Prix 2021 II".

Shuji Ishikawa is the inaugural winner of the tournament; Konosuke Takeshita is the only two-time winner.

Rules

 * The matches are fought to one fall with a 30 minutes time limit. The final has no time limit.
 * The participants are divided into two blocks, A and B, and fight in a round-robin using a points system; two points for a victory, one point for a draw, and zero points for a loss.
 * The winners from the two blocks go on to fight in the final to decide the D-Oh Grand Prix winner.
 * The D-Oh Grand Prix winner, assuming they do not already hold the KO-D Openweight Championship, obtain first contendership to the title and receive a title shot.
