It is vain to wish sublime ethics in business. Because business is a world where the weak are victims of the strong by selfinterest. But business is not a war. It is a game to play according to rules. Japanese business circles have made light of the rules. There has not been the game. In future, it will be necessary to establish clear and impartial rules, and to play the game according to the rules. But the game cannot be played on too strict rules. Because there is not freedom, autonomy, responsibility and vitality.
