Japanese Culture - Family Structure

One culture that is different than us is the Japanese culture. Specifically, their family structure is one of the main differences. As one may know, in America, family members don't all live together at a certain age. In other words, grandparents don't usually live with the parents; like so, the children don't live with the parents usually after a certain age. In Japan, however, it's a different story. All three generations of grandparents, parents and children alike all live together.
