Tsumugi is a premium silk fabric with distinct characteristics that vary by region.
Ichimoku crafts special Samue using Tsumugi from famous Japanese regions such as Shinshu and Yuki.
Shinshu Tsumugi is characterized by its deep luster achieved through natural dyes, primarily from plants, and traditional dyeing techniques. Yuki Tsumugi is designated as a National Important Intangible Cultural Property and is known as the "King of Tsumugi."
