While Rukia Kuchiki initially describes Soul Society as something of a paradise, where nine out of ten times it is better than the living world and hunger is never a problem, Soul Society is far from sublime. In fact, aside from the slowed aging and aforementioned lack of hunger, life there is much like that in the living world.
Soul Society consists of the Rukongai, where souls live when they arrive in Soul Society, and Seireitei, which is at the center of Soul Society. The mode of life here closely resembles that of feudal Japan.
The Human World and Soul Society are parallel to each other and are two sides of the same coin. Families separated by death are rarely reunited in the Soul Society unless they arrive in Soul Society together. People live nestled together like a family of strangers. One never gets hungry (if she or he doesn't have spiritual powers) and aging is slowed to a great extent, with lifespans of 2000 or more years not being unheard of, though such ages are limited to Shinigami or other Soul Society dwellers with high spiritual power. Children can be born as they are in the Human World. People can also be killed as regular Humans are, though they are capable of surviving wounds that would normally be considered fatal. A soul that dies in Soul Society is reincarnated on Earth as a new Human with no past memories.
