Coach Types and Roles
NPB teams employ multiple specialized coaches: pitching, hitting, fielding-baserunning, battery, and bullpen coaches. First and second teams each have coaches, with some teams employing 10-plus total. Coach responsibilities extend beyond technical instruction to mental care, conditioning management, and in-game tactical advice. While managers set team direction, coaches directly develop players. NPB teams employ 10-15 coaches across specialties: pitching, hitting, fielding-baserunning, battery, and bullpen. First and second teams each have 5-7 coaches, with SoftBank's three-team system employing 20-plus total. Coach salaries typically range 10-30 million yen, with head coaches earning approximately 50 million.
