Work.
The apprenticeship system was used in Japan. The boy had to serve a long apprenticeship with no pay, or but little pay, although his needs of food, clothing, and lodging were attended to. Somewhat akin to this was the entering of boys into the homes of those of distinction and education. The young men performed the services required about the home and they were cared for by the ones having them in charge and given instruction in the things needed by them for the future.
