Tendency of affection with which Japaneses treat on small cute things has been well known, even through the book “Reduction-oriented Japanese (The compact culture)”. When Japaneses expose their feelings toward such ‘small’, ‘cute’, and so, ‘lovely’ objects, they will shout without hesitation ‘Kawaii~’. I will probe on this paper where the affection to ‘KAWAI’ originated from and has been inherited as an aesthetic sense. After, ‘Kawaii’-style aspects in modern Japanese pop culture and ‘Kawaii’-code as a cultural strategy towoard global-era world shall be discussed on. As a result, followings could be confirmed. Aesthetic ideas representing Japanese beauty from the ancient times being developed, Japan had a culture which appreciate positively small and immatured things and enjoy them. Such a peculiarity of Japanese culture acknowledged private values on small young things and continuously expanded the applicable range of ‘Kawaii’. Also, ‘Kawaii’ in the modern Japanese pop culture made people forget about their age and gender, and such a culture was recognized as giving consolations to the human mind. And Japanese government has been making strategically use of ‘Kawaii’ culture as a part of the ‘COOL JAPAN’ project to be a national-brand cultural goods.
