Known as the Robot Kingdom, Japan has launched, by granting outstanding governmental budgets, a new strategic plan in order to create new markets for the RT (Robot-Technology) Industry. Now that the social structure is greatly modernized and a high social functionality has been achieved, robots in society are taking a popular role for Japanese people. The motivation for such great high-tech developments has to be researched in the context of how human relations work, as well as in the customs and psychology of the Japanese. By examining the background of the Japanese affirmativeness toward robots, this paper reveals the Animism and the Japanese ethics, Rinri, that benefit Japanese Robotics. First, the introduction describes the Japanese social context which serves to illustrate the term Rinri. The meaning of Japanese Animism is explained in order to understand why Rinri is to be considered as an incitement for Japanese social robotics.
