I’ve always wondered what the extent of fighting was between the Japanese and the Russians, I know they fought at Manchuria but where else did they fight or was it just mainly at Manchuria?
Are you referring solely to WWII or are you referring to a different period?
Russia and Japan had a series of conflicts (not all breaking out into open warfare) dating back to before the Ruso-Japanese war of 1904-5. The two major waves of fighting occurred in 1904-05 and 1945. But other periods of tension include 1895, 1918-1922, 1938-1939. All but the first included fighting in Manchuria.
