Black Dragon Society

The , or the Amur River Society, was a prominent paramilitary, ultranationalist group in Japan. History The Kokuryūkai was founded in 1901 by martial artist Uchida Ryohei as a successor to his mentor Mitsuru Tōyama's Gen'yōsha. Its name is derived from the translation of the Amur River, which is called Heilongjiang or "Black Dragon River" in Chinese (黑龍江?), read as Kokuryū-kō in Japanese. Its public goal was to support efforts to keep the Russian Empire north of the Amur River and out of East Asia. The Kokuryūkai initially made strenuous efforts to distance itself from the criminal elements of its predecessor, the Gen'yōsha. As a result, its membership included Cabinet Ministers and high-ranking military officers as well as professional intelligence operatives. However, as time passed, it found the use of criminal activities to be a convenient means to an end for many of its operations.
