Sarashi (さらし) may be one of the most humble yet versatile items in traditional Japanese daily life. While many people outside Japan may recognize it from pop culture — often associated with martial arts, samurai, or even yakuza imagery — sarashi has a long and practical history that goes far beyond these dramatic depictions.
In this guide, we’ll explore what sarashi is, where it comes from, and how it’s still used across multiple aspects of Japanese life today.
What Is Sarashi?
At its core, sarashi is a long, narrow strip of unbleached or white cotton cloth. Its name literally means “bleached” or “exposed,” referring to the whitening process traditionally used to prepare the fabric.
Key Characteristics
- Material: 100% natural cotton
- Breathable and comfortable on skin
- Flexible: easily cut or adjusted to desired length
- Washable and reusable
- Available in various widths and lengths depending on intended use
Its simplicity is its strength: a single roll of sarashi can serve countless purposes across both traditional and modern life.
Traditional Uses of Sarashi
Body Support and Protection
For centuries, sarashi has functioned as a kind of traditional compression garment:
- Samurai and martial artists wrapped it around their torsos for:
- Core stabilization
- Posture support
- Light injury protection during training or battle
- Craftsmen and laborers used it for back support during physical labor.
- It served as an early form of athletic taping or binding before modern compression wear existed.
Cultural and Ceremonial Use
Sarashi has long appeared in various aspects of Japanese culture:
- Martial arts: worn under uniforms or armor.
- Traditional performances: kabuki actors or festival participants may use sarashi as part of their costumes.
- Religious ceremonies: worn by some shrine or festival participants as a symbol of purity, discipline, and spiritual focus.
- Kimono dressing: helps shape and stabilize the body to create the clean, elegant silhouette essential to proper kimono wear.
The Yakuza Mythology
Modern media often portrays yakuza or gangsters wearing sarashi wrapped tightly around their torsos:
- This image symbolizes resolve, toughness, and readiness to face hardship.
- While rooted in some reality, its actual historical use among yakuza was far less widespread than pop culture suggests.
Modern Uses of Sarashi
Even in contemporary Japan, sarashi remains surprisingly useful:
Sports and Physical Activity
Though modern compression gear has largely replaced it, sarashi is still used by some athletes or practitioners for:
- Light injury prevention
- Posture correction
- Core support during weight training or martial arts
- Muscle compression to manage minor strains or swelling
Medical Support
- Occasionally used as gentle abdominal or chest support for postpartum mothers or after certain medical procedures (always under professional guidance).
Kimono Dressing (Still Widely Used)
- Helps flatten the chest for smooth kimono fit.
- Secures layers of kimono fabric in place.
- Supports proper posture, which is essential for formal kimono appearance.
Kitchen and Household Use
Sarashi serves as an indispensable multipurpose cloth in many Japanese kitchens:
- Straining broths, soy milk, or miso
- Wrapping and steaming food items
- Drying delicate dishes
- Covering fermenting foods
- Reusable wrapping cloth (eco-friendly alternative to disposable products)
Proper Usage Guidelines
Basic Rules for Safe Use
- Do not wrap too tightly — avoid restricting breathing or circulation.
- Apply smoothly without wrinkles to prevent pressure points.
- Pay attention to comfort and skin sensitivity.
- Monitor the area for signs of irritation or numbness.
When to Avoid Using Sarashi

Care Instructions
Sarashi is durable and long-lasting when properly cared for:
- Hand wash or gentle machine wash with mild detergent.
- Rinse thoroughly to remove soap residue.
- Air dry in shade to prevent fabric weakening.
- Store in a clean, dry place.
- Avoid prolonged exposure to direct sunlight to prevent fabric discoloration.
Summary: A Timeless Tool of Japanese Daily Life

Whether worn under a kimono, used for light physical support, or found in a kitchen drawer, sarashi continues to serve generations with its versatility and humble design. Its longevity is a testament to Japan’s ability to merge practical needs with cultural continuity.
