Do the Japanese have a particularly Japanese perspective of war and peace?

Win, be killed or commit suicide were the three standard option for the Japanese soldier during WWII. Officers that failed were expected to kill themselves. They had Kamakaze pilots. How were these ideas represented in Japanese popular culture. How did these ideas change after the unconditional surrender of Japan at the end of WWII. Were all Japanese soldiers expected to kill the,selves. How did this effect the Japanese culture?
