After a child has grown to a certain extent, parents named them according to their characteristics. Preparations to become an adult began at around 13 years of age. Boys were then able to attend ceremonies, and help out with hunting and fishing, and girls wore a kind of chastity belt, and were tattooed. At around 17, Ainu young people were deemed adults, and were allowed to marry. When a person died, they were buried together with their daily tools. This was so that the dead would be able to live similarly in the afterlife as they did when they were alive.
