Why don’t you see if he is translated into Russian?
In any case, Wiki states this:

The Kwantung Army of the Imperial Japanese Army under General Otsuzo Yamada, was the Japanese force opposing them. It was the major part of the Japanese occupation forces in Manchuria and Korea, and it consisted of two Area Armies and three independent armies [7]:
* First Area Army (northeastern Manchukuo), including: o 3rd Army. o 5th Army. * Third Area Army (southwestern Manchukuo), including: o 30th Army. o 44th Army. * Independent units o 4th Army (an independent field army responsible for northern Manchuria) o 34th Army (an independent field army responsible for the areas between the Third and Seventeenth Area Armies) o Kwangtung Defence Army (responsible for Mengjiang) o Seventeenth Area Army (responsible for Korea; assigned to the Kwantung Army in the eleventh hour, to no avail) * Other forces o Japanese Fifth Area Army - responsible for South Sakhalin and the Kuriles
Each Area Army (the equivalent of a Western “army”) had headquarters units and units attached directly to the Area Army, in addition to the field armies (the equivalent of a Western corps). In addition to the Japanese, there was the forty thousand strong Manchukuo Defense Force, composed of eight under-strength, poorly-equipped, poorly-trained Manchukuoan divisions. Korea, which would have been the next target for the Far Eastern Command, was garrisoned by the Seventeenth Area Army.
The Kwantung Army had over six hundred thousand men in twenty-five divisions (including two tank divisions) and six Independent Mixed Brigades. These contained over 1,215 armored vehicles (mostly armored cars and light tanks), 6,700 artillery pieces (mostly light), and 1,800 aircraft (mostly trainers and obsolete types; they only had 50 first line aircraft). The Imperial Japanese Navy contributed nothing to the defense of Manchuria, the occupation of which it had always opposed on strategic grounds.
On economic grounds, Manchuria was worth defending since it had the bulk of usable industry and raw materials outside of Japan and still under Japanese control in 1945. However, the Japanese forces were far below authorized strength, and most of their heavy military equipment and best military units had been transferred to the Pacific front over previous three years. As of 1945, the Japanese army in Manchuria contained a large number of raw recruits. The result was that the Kwantung Army had essentially been reduced to a light infantry counter-insurgency force with limited mobility and experience. In the event, Japanese forces were no match for the mechanized Red Army, with its vastly superior tanks, artillery, officers, and tactics.
Compounding the problem, the Japanese military made numerous mistakes. First, they assumed that any attack coming from the west would have to follow either the old railroad line to Hailar or head in to Solun from the eastern tip of Mongolia. The Soviets did attack from both those routes, but their main attack went through the supposedly impassable Greater Khingan range south of Solun and into the center of Manchuria. Second, the Japanese military intelligence failed to determine how many troops the Soviets were actually transferring to the Siberian front. Their military intelligence predicted, based on erroneous numbers, that an attack was most likely in October of 1945 or in the Spring of 1946.
New plans made by the Japanese in the summer of 1945 called for the borders to be held lightly and delaying actions fought while the main force would hold the southeastern corner in strength (so defending Korea from attack). However, the new plans were not implemented by the time the Soviets launched their attack.
