Japanese Intelligence

During World War II, Japan's intelligence organization had several elements. Abroad, embassies played a key role cooedinating intelligence-gathering. Within Japan, the Tokko - a special bureau of the Tokyo police force - was responsible for domestic counterintelligence. The armed services also had their own intelligence sections, with the military police (Kempei Tai) covering counterintelligence activities in territories occupied by the Japanese.

The Tokko was formed in 1911with the purpose of suppressing "subversive thoughts" and defending Japan's strictly regulated political system. It did much to prevent the rise of communism in Japan in the years after World War I.
