In this paper, a methodology for self-organization of autonomous agents is proposed. Agents make an organization to adapt their environment, building an adaptable soccer team. In soccer games, each player must forecast correctly, and players behave strongly as a team. They must also react and reform team plays if accidents happen by statistical movement of the ball. To adapt the soccer environment, we introduce an on-time communication style among autonomous agents, pheromone communication. Agents as players give their forecasting (represented by pheromones) acquired by the learning ability of each agent. Using by forecasting, they discuss and reform team play. With this learning ability in forecasting by each player, we expect they will make a close soccer team. When they start learning, they cannot behave sophisticatedly but, after sufficient learning trials, they behave like offensive professional players.
