The King of Dark Championship was a professional wrestling championship created by Amon Tsurumi. The champion was forced to wrestle exclusively in dark matches on DDT shows. Contrary to regular professional wrestling championships, the title was not rewarded to the winner of the match, but was given to the loser instead.

DDT Pro-Wrestling is a Japanese professional wrestling promotion based in Shinjuku, Tokyo. Its name stands for Dramatic Dream Team, which was the promotion's official name from 1997 to 2004. Founded in March 1997 by Shintaro Muto, the promotion was eventually bought and managed by Shoichi Ichimiya until December 2005, when Sanshiro Takagi took over as the new president. In 2017, DDT was sold to CyberAgent. Takagi retained his position, while Takahiro Yamauchi took over as the new DDT director.
