Sashiko is a form of traditional Japanese hand embroidery which uses a basic running stitch to create an intricate geometric design on fabrics. Initially, sashiko was a sewing method to repair the damaged cloth or reinforce the strength of the non-durable fabric. In the Edo period, sashiko was also used in making martial arts uniforms or firefighters’ workwear called ‘hikeshi hanten.’ Nowadays, sashiko is utilized for decorative purposes.

There are three major famous sashiko stitching styles such as Kogin-sashi handed down in the Tsugaru region of Aomori Prefecture, Hishi-sashi handed down in the Nanbu region of Aomori Prefecture and Shonai Sashiko handed down in the Shonai region of Yamagata Prefecture.
