In Japan, honor is shared amongst a family. Because of this, if a child goes on and becomes a major success, he or she earns honor for not only him/her-self, but also for the rest of his/her family. At the same time, if a family is mostly made up of good people, they can still all be dishonored and disgraced if a single member does something shameful. Thus, this is one of the major reasons that people in Japan commit suicide, for dishonoring their relatives.
Honor is important to the Japanese because they needed something really substantial and deep to balance out all the other crazy stuff they do like pooping in each other's mouths.
Honor
Honor is a very important thing in Japanese culture even more so than the Chinese. They'd rather die than surrender (the way of the samurai's or their Bushido) and there is no way to say surrender in Japanese, it just doesn't exist. They would rather seppuku (basically suicide) than bring shame or dishonor their family and suicide is tolerated in Japan and some think it is a way to maintain one's honor.
