It has been reported that 70-90% of robots (depending on how "robot" is defined) in the world are concentrated in Japan. This situation has been discussed much from the viewpoint of the employment pattern particular to Japan, a combination of the life-ling employment system and the seniority system. Taking this viewpoint fully into consideration, this appear will add a cultural perspective to the understanding of the popularity of robots in Japan. It analyzes that both Japanese people and robots are "ritual" beings and that the Japanese moral training is sequential. This particular conditioning of people in Japan creates relationships between the whole and the parts and also between body and mind, different from those which Western societies have developed and have been experiencing. In the Japanese mind, robots have been accepted as morally primitive but not evil. In the image particularly of Japanese children, robots become super men when they gain the beauty of the human heart.
