The present paper articulates an incipient theory of the cultural context of Japanese sexuality. The theory was developed while the present author was a Visiting Professor of Psychology at Kyoto University in Japan. Reference was made to Japanese customs, laws, psychology, and mythology. A small sample of .contemporary Japanese literature was also reviewed as a point of illustration, and a measure of ecological validity. This literature represented 5 of the most critically acclaimed, and widely read, Japanese authors. Conclusions were drawn, and biases were discussed.
