Primarily it was cultural attitude. To the Japanese military mind of the time (and to a surprising extent, the the Japanese corporate mind of today) the individual is not important, but absolute discipline and obedience to superior authority was. Individual initiative was discouraged. This was so thoroughly inculcated into the individual, that even in a crisis, individuals often refused to take the initiative, especially in the enlisted ranks. When soldiers and sailors are so conditioned, they are often paralyzed without direction in a crisis. If, under those circumstances, the chain of command is broken, disaster results. Additionally, the ideal of dying for the Emperor and the Empire does not help the normal instinct for self preservation, which is a tremendous motivator when properly applied through training. Furthermore, the myth of Japanese racial superiority and invincibility has its roots hundreds of years in the past. This was why their aircraft had little or no armor protection for the crew—and the attitude affected everything they did, and the way they thought about it. Damage control would be unnecessary, or at least minimal, because they would rarely take much damage. Note that this is an attitude, largely unconscious but always present. If you could ask a Japanese naval officer of the time whether damage control was necessary, he would have responded with an incredulous, "Of course!" But deep down, he wouldn't quite believe it as thoroughly as someone from a different culture
By contrast, US forces personnel, both by training and social inclination, will willingly take matters into their own hands in a crisis, occasionally even to the point of a seaman who knows what needs to be done giving orders to those who don't but outrank them (and are intelligent enough to realize they don't know.) Sadly, this is becoming less and less the case.
For insight into the Japanese psychology, particularly with regard to combat and war, I recommend:
Miyamoto, Musashi; The Book of Five Rings
Munenori, Yagyu; Life-Giving Sword
Wilson, William Scott; Lone Samurai, the Life of Miyamoto Musashi
Craig, Darrell; Iai, the Art of Drawing the Sword
Caiger, Mason J.; A History of Japan
Dunn, Charles J, and Broderick, Laurence; Everyday Life in Ancient Japan (I think this is the one. I found it in a Japanese bookstore, wrote down the information intending to find it on Amazon, and then lost it. Grumble.)
And that's just a start.
