Societies and people that direct fashion with their cultural heritages and modern interpretations have had a significant place in fashion history in every period. Cultural streams have a big influence on fashion world that is formed with synthesis of various factors such as social and political facts, immigrations, economy and advancing technology. In this study, the distinctive clothing style, life style and design insight of the Japanese culture were researched and, by analysing their collections it was aimed to determine the concepts and silhouettes that the Japanese designers have brought in the fashion world.  There has been a period of cultural change in fashion especially with the rapid boom of Japanese fashion designers that are defined as innovative on Paris podiums and each of these designers became an icon in fashion history. The introduction of the Japanese design into the modern fashion world began with Hanae Mori, continued with Kenzo Takada and gained momentum with Issey Miyake from the second generation and Yohji Yamamato and Rei Kawakubo from the third generation. Miyake Yamamato and Kawakubo, who set the stage for the development of a post-modern interpretation in fashion, went down in history as the designers that led to the development of a fashion icon known as the Japanese avant-garde. With their anti-aesthetic and asymmetrical designs, the Japanese designers that led to existential questionings about what the clothing means pioneered the change of the old terminology. Bringing a new approach to the Western fashion insight and clothing habits that is based on body ideals, the Japanese designers presented a quite impressive alternative with their fabric technologies and plain styles.
