It is beneficial to study U.S. top junior volleyball clubs when we consider how junior ／ youth players in Japan are trained and supported. conducted on-site interviews on the coaches of the several top junior teams in the United States. As a result, their training environments and methods were revealed based on coaching policies, methods, motivations and expectations for the players. Clubs have their own court and carry out phased special program with specific goals and policies divided into ages. Clubs try to bring up and train players by dividing them with a merit-based system. Coaches can select working conditions and have two jobs if they get the licenses. So we can expect that the number of coaches will increase, and they will be motivated more to train players. Also their skills for training will be improved. It is likely that improving the system for club influences training junior volleyball players in U.S. positively.
