Ultimate Party 2019: DDT Group Big Gathering! (Ultimate Party 2019〜DDTグループ大集合!〜, Ultimate Party 2019: DDT gurūpu dai shūgō) was a professional wrestling event promoted by DDT Pro-Wrestling (DDT). The event took place on November 3, 2019, in Tokyo at the Ryōgoku Kokugikan. It was the first event under the Ultimate Party chronology. The event featured fourteen matches, nine of which were contested for championships.[1][2] The event aired live on DDT's streaming service DDT Universe.
There have been three pre-show matches. During the last one, two folding chairs fell on Shota, who was the 1,432nd Ironman Heavymetalweight Champion. Referee Yukinori Matsui counted this as a pinfall and awarded the title to the chair that was "pinning" Shota. He then counted a second pinfall as the second chair was lying on the first thus "pinning" it. As a result, the second chair was added to the participants of the Rumble rules match as the 1,434th defending champion. The main card had eleven matches, with the main event portraiting the winner-takes-all confrontation between the DDT Extreme ChampionHarashima and the KO-D Openweight ChampionKonosuke Takeshita. Harashima succeeded in defending his title and won the Openweight title for the tenth time in his career.[4]
