The company was founded over forty years ago in Japan by Eisaku Noro. The handcrafting yarns in particular are well known for their vivid colors and combinations of diverse fiber types. They differ from a number of other manufactured yarns in the industry by having lengthier spans of color in the runs, causing distinctive striping patterns.
All animal fibers that are used in the yarns come from certified organic farms, from international sources such as Australia, the Falkland Islands and South Africa. Eisaku Noro is personally involved with inspecting all aspects of production, from visiting the animal farms to checking the machinery used and keeping restrictions on the dye processes to maintain products that are as eco-friendly as possible.
