Case management lies at the foundation of clinical activities for youth with early psychosis. While introducing the systems and skills accumulated in Anglo-American countries, the author affirms tasks associated with care management in Japan. The characteristics of case management for youths with early psychosis are as follows : 1）a primary therapeutic model, 2）emphasizing engagement by means of outreach, 3）limiting caseloads for the sake of fostering collaborative relationships, 4）adopting a method of active brokerage, and 5）establishing time limits of two or three years. The author calls for the establishment of a new training system for implementing these activities in Japan,due to the existence of significant misunderstandings of care management in that country.
