Japanese aesthetics and K.UNO designs

The designs of K.UNO are rooted in respect for nature: strength, gentleness and beauty.
Japanese ukiyo-e, which played a significant role in the development of Art Nouveau, expresses the magnificence and beauty of nature as art and has great impacts on western countries. Such a high sense of aesthetics and exquisiteness and unique culture are rooted in Japan.

More than 50 designers pursue their crafts at K.UNO. They offer an enormous variety of designs to meet customers' requests. Consulting with customers diligently and drawing designs right in front of the customers, they produce more than 40,000 designs each year. K.UNO designs are drawn from each customer's unique concepts and thoughts and given shape by the designers.
