Abstract
The author wished to clarify the four important reflections on the urgent ethical problems in the information-society, which is, according to the author’s opinion, the technological conjuncture. 1) What is the traditional conceptual knowledge of information in the Japanese feudalistic society and its historical influence on the modern society in Japan. 2) The post-modern drastic change of the concept of information in the technological conjuncture as Japanese recent society. 3) Ethical problems from the side of informative authority as government or sponsors and from the side of the receivers as citizens. 4) The essential relations between information-ethics and the aretology (theory of arete, namely virtues) of eco-ethica. There are many important suggestions concerning the ethical attitude in the moral relation in the so-called virtual reality, namely on the moral dimension entirely different from the relation “in face to face”.
