In particular, the FSB website published documents on the interrogations of Japanese military leaders, including Lieutenant General Kiyoji Tominaga, who developed the first operational plan for Japan's attack on the USSR.
“In 1940, being the chief of the 1st department of the general staff of the Japanese army, I developed a plan for an attack on the USSR.
The operational plan developed by me provided for the main strike against the Red Army in the area of Lake Hanko, followed by the capture of Khabarovsk, with the expectation of cutting off the Soviet Far East from the rest of the USSR, "Tominaga said during interrogation on February 11, 1946.
According to the military, after Germany's attack on the Soviet Union, the Japanese government in conspiracy with Adolf Hitler proposed to the Japanese General Staff "to accelerate the preparation of an attack on the USSR."
In August, the FSB first declassified documents according to which Japan planned to use a bacteriological bomb in 1944.
