Exactly right, asif.
It is thought that follow on attacks would have taken out the oil storage and other facilites. Those second wave of strikes were intially planned as I undertsnad it, but Yamamoto ordered them to withdraw after he heard the damage that had been inflicted.
In the long run it probably would not have made much of a difference. But in the short run, it sure would have hampered and slowed initial operations being staged out of the Hawaiin Islands.
Yamamoto was a fine Admiral Pearl harbour was a text book manoeuvre but the way he thought was that he has scored 90% damage with minimal losses why risk possible losses (due to element of suprise being lost) to get another 10% more? But the point was that that extra 10% was really important
The crack Japanese fighter aces were reporting back huge losses Imperial Japan was happy and they regrouped and left
Japan had only a few hundred very highly skilled pilots who had seen war since 1931 and 1937 in China and South Asia they had developed thier skills and mastered the art of carrier opps, but they were rigid and institutionalised never passing on thier knowledge and experience, when killed they took it all with them, most of them killed at Mid way
In all honestly Imperial Japan wasn't fit for war against a resource rich nation they were ok against weak nations, although very deadly at the middle scale level on a large scale the overall larger stratedgy was not in thier favour
Having said that they Zero fighter pilots ran circles around the RAF and Royal Navy Fleet in Asia, Britain was totally outclassed by thier Japanese counterparts they almost seemed invincible in 1941 to summer of 1942
