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 firefighter’s workwear called ‘hikeshi hanten.’ Nowadays, sashiko is utilized for decorative purpose.

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