When we think of sarashi cloth, it naturally reminds us of the seamstresses of old.
Much like the senninbari, I too remember being made to wear a thimble on my finger and forced to race against others—competing in speed as if it were a footrace.
In the past, when kimono fabric became worn out, people would repurpose it into padded jackets or cushions. Sewing was seen as one of the essential skills for a bride-to-be, a foundation of women’s training.
Turning to the world of sushi, this same high-quality sarashi cloth is indispensable. In fine sushi restaurants, you often see it used to wipe knives or spread neatly on the cutting board.

2. What is Sashiko?
Sashiko is a traditional embroidery and reinforcement technique in which regular, small running stitches are layered on fabric. In cold regions and fishing villages, layering cloth with stitches enhanced warmth and durability, while at the same time giving decorative value through geometric patterns.
- Materials: Indigo-dyed fabric × white cotton thread (clear contrast).
- Patterns: Hemp leaf, shippo (linked circles), arrow feather, seigaiha (waves)—all motifs with auspicious meanings.
- Regions: Regional variations include Kogin-zashi of Aomori and Shonai sashiko of Yamagata.
Today, sashiko has expanded into visible mending for clothing as well as bags, cushions, and other interiors, and is revalued as a handcraft well-suited to a sustainable lifestyle.
3. What is Senninbari? (Culture and History)
Senninbari (“thousand-person stitches”) were prayer belts made mainly during the wartime period. Women and community members stitched tiny running stitches one by one into a sarashi cotton cloth belt, wishing for the safe return of departing soldiers.
- Practice: The ideal was to gather stitches from “a thousand people,” but in reality relatives and neighbors cooperated to add many stitches. Red thread was often used, symbolizing protection against evil.
- Material: The base was cotton sarashi cloth—portable, practical, and wearable against the skin.
- Nature: It functioned both as a practical item and as a protective talisman. While tied to the wartime background, it embodied communal solidarity and prayer.
Senninbari shares with sashiko the element of regular running stitches that strengthen fabric. However, while sashiko emphasized reinforcement, warmth, and decoration, senninbari was centered on protection and symbolic prayer.
4. Connecting the Three: Material, Technique, and Symbolism
- Material (Sarashi): Absorbency and hygiene (sushi kitchens), strength and processability (sashiko), portability and wearability (senninbari).
- Technique (Running Stitch): Based on the running stitch, where repetition and rhythm imbue fabric with both function and meaning.
- Values: Cleanliness, durability, solidarity, prayer. A common foundation of Japanese daily culture.
From this perspective, even a single piece of sarashi cloth on a sushi chef’s workbench embodies more than its practical use (wiping, lining). It symbolizes the broader relationship between fabric and people—caring, reinforcing, and wishing—that connects sashiko and senninbari alike.
5. Practice: Starting Sashiko & Visible Mending with Sarashi (Super Simple)
- Choose Fabric: Cotton sarashi (or tenugui). Avoid overly thick cloth for easier stitching.
- Choose Thread: Sashiko thread or thick cotton thread. Beginners will find white or natural colors easiest.
- Marking: Draw guide lines 5–7mm apart with tailor’s chalk for even stitches.
- Stitching: Use the basic running stitch. Fold fabric slightly as you advance the needle, avoiding pulling thread too tight.
- Finishing: Secure thread ends by backstitching a few stitches. Press with an iron to smooth.
Start with reinforcing high-wear areas such as denim knees or apron corners to feel the practical effect quickly.

7. English Summary
Sarashi (bleached cotton) is a versatile cloth used in Japanese daily life. In sushi kitchens, it serves as a hygienic wiping and lining cloth. Sashiko is a repetitive running-stitch technique that reinforces and adorns textiles—traditionally white cotton thread on indigo cloth, now widely used for visible mending. Senninbari (“thousand-person stitches”) are protective belts made mainly from sarashi, with small stitches contributed by many people as a communal prayer for safety. All three share a common material (cotton), a common technique (running stitch), and common values: cleanliness, durability, solidarity, and care.
