Japanese air power in a hypotetical invasion of the USSR in 1941

[Shinpachi]

Japan had no remarkable reason to make war with Russia, or Soviet Union, after the Russo-Japanese war of 1904 at all as obtained Korean Penninsula.

Hello, Jenisch. Have you ever checked the Battle of Shumshu before?
As you may know, on August 17 1945, approx 8,000 Soviet troops suddenly invaded a Japanese nothern small island, Shumshu, to be smashed by the joint IJA/IJN garrison. You will realize how tough they were as Soviet Union had to give up to reach to Hokkaido, the second largest island of Japan after all.

Hi Shinpachi San

I agree that the japanese were a tough opponent for any enemy, but Shumshu is considered a Soviet victory in the west. Losses were very similar for each side, but the Soviets did take the place. It was at a very heavy cost however.

With Shumshu and Paramushiro under Soviet control, the rest of the Kuril Island chain, much more lightly held by Japanese forces, fell to Soviet forces easily. The Soviets completed their occupation of the Kurils on 5 September

Its problematic that the battle saved Hokkaido from invasion...perhaps.

The Battle of Shumshu was, of course, Soviet's victory as Japan herself had accepted the Potsdam Declaration on August 15.
The garrison fought under the cease-fire order as invasion did not stop.

I did not say it was Japan's victory but they smashed the Soviet troops with far less casualty than the opponent.
According to our local wiki, it was approx. 600 vs 3,000 not 1,018 vs 1,567 as Soviet claimed.
