In 1998, 『SOPH.』 was founded by Hirofumi Kiyonaga. Under the concept of minimal design, it has started its business seeking for the sophisticated daily wear. With focusing on the surplus details for multi-usages and the quest for the high-tech materials, it has created and developed the collection of functional casual clothes for daily use. After that, SOPH. has been trying to convince that you can feel a kind of Japanese aesthetic beauty through the cloth material containing Binchotan. The philosophy that the comfortable clothes good for urban dwellers should be functional-oriented has so far affected not a little the trend of street fashion and such innovative point of view of 『SOPH.』 has received widespread attention.
