The KO-D (King of DDT) 10-Man Tag Team Championship (Japanese: KO-D10人タッグ王座, Hepburn: KO-D Jū-nin Taggu Ōza) is a professional wrestling championship owned by the DDT Pro-Wrestling promotion. Meant for teams of five wrestlers, the title is believed to be the first of its kind in professional wrestling.^[2] The title was first announced on April 30, 2017,^[1] with the inaugural champions crowned on August 20, 2017.^[3]

Like most professional wrestling championships, the title is won as a result of a scripted match. The current holders are Schadenfreude International (Antonio Honda, Masahiro Takanashi, Takeshi Masada, Mecha Mummy and Takayuki Ueki).

Recognizing the difficulty of scheduling matches for the title, DDT announced that as long as the captain of the reigning champions and two other members are present, title matches can be held with two replacement members taking the other two spots in the team. These replacement members would, however, not be recognized as official champions.^[4]

On December 21, 2020, the title was vacated and became the KO-D 8-Man Tag Team Championship due to the difficulty of scheduling a proper title defense during the COVID-19 pandemic.^[5][6]

On February 14, 2021, at Kawasaki Strong 2021, the team of Shinya Aoki, Super Sasadango Machine, Antonio Honda and Kazuki Hirata won the vacant title.^[7] On March 28, at Judgement, they lost the title in their first defense against Team Thoroughbred (Sanshiro Takagi, Yukio Naya, Chikara [ja] and Yakan Nabe [ja]).^[8] On December 28, it was announced that the title would revert to its original 10-man tag team form with the team of Sanshiro Takagi, Akito, Soma Takao, Gota Ihashi and Yuki Ishida challenging in a 5-on-4 handicap match on January 3, 2022.^[9]

As of May 11, 2024, there have been a total of nine reigns shared between nine different teams composed of 36 individual champions and two vacancies. Ken Ohka, Ladybeard, LiLiCo, Makoto Oishi and Super Sasadango Machine were the inaugural champions. Their inaugural reign was also the longest at 770 days while Shinya Aoki, Super Sasadango Machine, Antonio Honda and Kazuki Hirata's reign is the shortest at 42 days. Honda is also a record three-time title holder. Yoshiaki Yatsu is the oldest champion, winning the title at 64, while Asuka is the youngest at 21.

The current champions are Schadenfreude International (Antonio Honda, Masahiro Takanashi, Takeshi Masada, Mecha Mummy and Takayuki Ueki), who are in their first reign as a team, with Honda being in his third individual reign.
