In Japanese culture, the group is important and the individual has no worth. The invididual is expected to sacrifice their lives for the group all the time - for instance the Kamikazi pilots.

One consequence of this lack importance attached to individual human rights in Japan is that they murder their old people when it's decided they can no longer contribute to society. The Japanese say this was a historical practice which they don't do anymore, but that's a lie. They still regularily kill older people which is part of why their suicide rate is so high amongst older people.

Men are given worth in Japan's culture, but not women. An Old Man, even infirm and helpless, is considered important as the head of a family. Men can contribute simply by being alive, but older women have to prove their worth. When a woman gets old, she is considered a burden on the community.

In Japanese Culture they have historically ritualized the murder of their elders in a ritual called: Ubasute. The literal translation of the term is "to abandon an old woman." In the ritual, the elder (grandmother or great aunt, etc) is carried out to the middle of a forest or mountainside and then abandoned and left to die.

While women were the one's usually ritually murdered, the Japanese would also kill fathers who were considered a burden to the family. In this case the ritual is called, "Oyasute" (which translates to "abandoning a parent"). Ubasute is celebrated in Japanese folklore, where it forms the basis of many legends, poems, and koans.
