Order of the Black Dragon

The Black Dragon Society (Kokuryūkai in Japanese) was a prominent paramilitary, ultranationalist right-wing group in real-life Japan founded in 1901 by Uchida Ryohei. Its name originated from the Amur River, called Heilongjiang or "Black Dragon River" in Chinese and read as Kokuryū-kō in Japanese.

The society was created to drive the Russian Empire out of east Asia, south of the Amur River. The Imperial Japanese Army made use of the Kokuryūkai network for espionage, sabotage and assassination as well as to spread propaganda and disinformation.

the Black Dragon Society was generally depicted as a sinister secret society bent on world domination, that sent highly trained agents such as the Man of a Thousand Faces, Mr. Kato, and Neper on important missions.

Heroes such as Minute-Man, Rusty Ryan, the Rangers of Freedom, the Cloak, Spy Smasher, the Black Condor, Captain Future, the Agatha Detective Agency, Pat Parker and her Girl Commandos, Commando Yank, and the Sniper all fought the Black Dragon Society or its agents at one point or another.
