It is a form of ikat dyeing, traditionally resulting in patterns characterized by their blurred or brushed appearance.
When woven together, the undyed areas interlace to form patterns, with many variations – including highly pictographic and multi-colored results – possible to achieve.
After the invasion of the Ryukyu Kingdom in 1609, kasuri techniques entered southern Japan and had moved northwards to the Nara area of Honshu by 1750.
[6] Increases in production continued until the 1930s, when the national government outsourced it to the new colonies, shipping pre-dyed threads abroad, where labour was cheaper.
Forced labour was used; in 1928, 54% of Japan's ikat weaving was done by unpaid prisoners in China and Korea.
