Dual Shock Wave is an annual professional wrestling tag team tournament promoted by the Pro Wrestling Wave promotion. It has been held since 2011 and takes place between early September and mid-November. The first tournament, held in a single-elimination format, was used to determine the inaugural Wave Tag Team Champions. In 2012, the tournament was changed to a round-robin format with the winners of each block advancing to the finals. In 2014, the tournament returned to single-elimination format. Since October 2013, the name "Dual Shock Wave" has also referred to the Wave Tag Team Championship.
List of winners
2011
The first ever Dual Shock Wave tournament was held in a single-elimination format between September 4 and October 30, 2011, and was used to determine the inaugural Wave Tag Team Champions. The pairings for each round were determined by a random draw. As the tournament featured an odd number of entrants, nine teams, one team earned a bye in the quarterfinals and one in the semifinals; these were also decided by a random draw.
Teams
2012
The second Dual Shock Wave tournament was held between September 25 and November 16, 2012. The tournament was contested in a round-robin format with two blocks of four teams, where a win was worth two points, a draw one point and a loss zero points. As the reigning Wave Tag Team Champions, Gami and Tomoka Nakagawa earned an automatic spot in the tournament. As the reigning Dual Shock Wave winners, both Ayumi Kurihara, now teaming with Mika Iida, and Kana, now teaming with Ayako Hamada, also earned automatic spots in the tournament. Three of the teams, Hikaru Shida and Yumi Ohka, Misaki Ohata and Tsukasa Fujimoto, and Shuu Shibutani and Syuri, earned spots in the tournament by scoring eliminations in a five tag team elimination match on September 3, 2012, which also included the teams of Aya Yuki and Sawako Shimono, and Maki Narumiya and Yuu Yamagata. Narumiya and Yamagata were named the reserve team of Block A and Yuki and Shimono the reserve team of Block B, where they would enter the tournament in case of an injury, inheriting the points of the eliminated team. The final two teams of Apple Miyuki and Kyusei Ninja Ranmaru, and Makoto and Moeka Haruhi were so-called "producer recommendation" picks made by Gami. The winners of the tournament, if not Gami and Tomoka Nakagawa, would earn a shot at the Wave Tag Team Championship on November 27 at Korakuen Hall.
2013
The 2013 Dual Shock Wave took place between September 1 and October 6. The winners of the tournament earned a shot at the Wave Tag Team Championship on October 30. Had the defending champions, Cherry and Shuu Shibutani, won the tournament, the title shot would have gone to the other finalist. The tournament was contested in a single round-robin block with eight participating teams. Hamuko Hoshi, Hikaru Shida and Tsukasa Fujimoto from Ice Ribbon entered the tournament as outsiders. In the tournament a win was worth one point, while both a draw and a loss were worth zero points. If a team drew or lost three times, they were eliminated from the tournament. The final match was a three-way match contested under "Dog Fight" rules, where only two teams were in the ring at the same time and after a pinfall or submission the losing team would switch places with the team not taking part in the match. The first team to pick up two consecutive pinfalls or submissions would be declared the winner.
