In Japan, there exist many sustainable companies. Their distinctive feature is mutualism; they often take altruistic behaviors. To explain such behaviors, we carry out iterated prisoner’s dilemma games by lattice gas model. Each lattice point is regarded as a company which contains m + 1 players with an identical strategy. Simulations reveal that All Cooperation wins, when m takes a value larger than a threshold. We obtain a power law depending on error level. This law implies altruism may prevail in a company which has many employees or high error level.
