Abstract
We have a try to develop the theory of “demands of identification and differenciation” that Simmel opened out. Here we apply this viewpoint to the topics of “Iki” and “Tsu” that have been seldom approached sociologically.
If we quote former studies of “Iki” and “Tsu”, we can make three types, “I Torimono= Iki=Kioigumi”, “II Tsu”, and “III Sui=Iki”. We offer a suggestion to take them in an united viewpoint as “struggle for prestige”, “Mode through the medium of the manuals” and “unstable emanations of two demands in the form of games”. In conclusion, we give a suggestion to interrelation of three atributes of “Iki” and the consequence of “Iki”.
