Japan sortites its fleet. If the search suceeds, they expect to inflict large losses to the invading transports and retard the next invasion by many months.
If the search fails, they will have the satisfaction of bringing Yamamoto and additional troops safely home, exactly on the required spot, Kagoshima, which is obviously the American target.
This time the forces meet, and there is no significant surprise.
The Ameriacn fly some additional land air, both fighters and bombers.
Overall, the air forces are roughly equal, although the US have more bombing factors and have a large advantage in AA.
Unseen here is the support of the Singapore British fleet of 18 vessels, led by 5 battleships but no carrier (they are stuck in Europe.)
