The Japanese buys themselves a year, perhaps.
While the military matter places the Japanese at a great advantage compared to OTL, I think the biggest improvement to the Japanese strategical situation will be the US lacking a submarine base at Midway. The US subs will have to base in Australia (hard to supply if the Japanese are intercepting the supply lines) or Hawaii, both of which are much further away from the vital Japanese supply lines between Manchukuo/Kora-Japan and Dutch East Indees-Japan. US subs will have less time to spend patrolling for Japanese merchant vessels as they will require more fuel to get to and back from the patrolling areas. This will help the Japanese economy quite a bit.
The Japanese will produce more planes, put a few more ships in the water and might even force a reverse or two on the Americans as they are advancing in early 1944. By summer 1946, it will be over, though.
Perhaps the Soviets taking Manchukuo and Korea as well as Mengukuo and the Japanese positions in northern China will scare the Americans enough to make peace on the "the Emperor is not affected" terms that the Japanese offered IOTL?
