Keiko Mawashi Explained: How It Differs from the Mawashi Used in Official Tournaments

The keiko mawashi is the training belt that every sumo wrestler wears during daily practice. It serves to protect the body, enhance the quality of training, and sharpen mental focus. Unlike the ornate kesho mawashi, it is plain in appearance yet vital for supporting a wrestler’s development.

The Basics of the Keiko Mawashi

The keiko mawashi is made of unsa cotton, a thick and durable fabric. Wrestlers ranked below makushita use it both in training and official tournaments, while those ranked jūryō and above wear it only during practice. It is typically about 7 meters long and 50 centimeters wide, tightly wrapped around the waist and secured with a knot.

Although it may look like a simple black or white cloth, it protects the wrestler’s body and improves the quality of training. For beginners and foreign fans, the keiko mawashi is often the first window into understanding sumo culture.

White vs. Black Keiko Mawashi

The keiko mawashi comes in different colors depending on the wrestler’s rank. Wrestlers ranked jūryō or higher wear white mawashi, while those ranked makushita or below wear black mawashi. This distinction is not just a custom; it clearly shows hierarchy within the sumo world.

Wrestler’s Rank	Color of Keiko Mawashi	When It Is Used
Below Makushita	Black mawashi	Training and official tournaments
Jūryō and above	White mawashi	Training only

The black mawashi symbolizes the hard-working younger wrestlers still climbing the ranks, while the white mawashi represents wrestlers who have reached the prestigious sekitori level.

Materials and Characteristics

Although plain in appearance, the keiko mawashi is carefully crafted from strong fabrics. The most common material is unsa cotton, prized for durability and protection.

Material	Characteristics	Effect on Wrestlers
Unsa cotton	Thick and durable	Prevents abrasions and bruises
Cotton cloth	Highly absorbent	Absorbs sweat and provides comfort
Hemp (historically used)	Light and breathable	Used in earlier times, especially in summer

Unsa cotton remains the standard material today, as it can withstand the demands of intense practice.

The Role and Purpose of the Keiko Mawashi

The keiko mawashi serves three main purposes:

1. Body protection
   The thick cloth shields the waist and abdomen, softening impacts from throws and falls.
2. Stability in movement
   When tied tightly, it stabilizes the hips, helping wrestlers perform fundamental moves such as shiko (leg stomps) and suri-ashi (sliding footwork) correctly.
3. Mental focus
   Putting on the mawashi is like a ritual that sharpens the wrestler’s mindset and prepares them for practice.

Steps to Tie a Keiko Mawashi

Since the mawashi is a long piece of cloth, it must be wrapped properly to avoid loosening during training.

Step	Method	Key Point
1	Place the end of the cloth against the hip bone	Secure the starting point firmly
2	Wrap tightly while pulling	Apply enough force to prevent loosening
3	Overlap 3–4 layers	Build thickness for stability
4	Tie securely at the end	Ensure it won’t come undone during practice

Experienced wrestlers develop their own methods, adjusting the tightness and folds to suit their body.

History and Background of the Keiko Mawashi

The keiko mawashi dates back to the Edo period, when wrestlers used simple hemp or cotton cloths. By the Meiji era, unsa cotton became common, shaping the modern version used today.

When a new recruit first wears a keiko mawashi, it symbolizes their official entry into the sumo world. Senior wrestlers or stablemasters usually assist with the first tying, passing down knowledge and tradition. This moment marks the beginning of their journey as a sumo wrestler.

The Keiko Mawashi in Training

Inside a training stable, wrestlers in black or white mawashi clash with full force. Even without decoration, the sight of wrestlers in keiko mawashi radiates intensity.

During morning practice, it is common to see wrestlers gripping each other’s mawashi to throw or push. The keiko mawashi acts as a pivot point for techniques, making it essential for offensive and defensive maneuvers. Sweat and dirt gradually make the cloth heavier, a physical testament to the harshness of training.

Differences from the Tournament Mawashi

The keiko mawashi differs from the mawashi used in official matches. Understanding these differences helps deepen appreciation for sumo.

Type	Characteristics	When Used
Keiko mawashi	Cotton, black or white	Practice, tournaments for lower-ranked wrestlers
Tournament mawashi	Silk, glossy finish	Official bouts for jūryō and above
Kesho mawashi	Ornate with embroidery	Ceremonial ring-entering rituals

The keiko mawashi is the battle gear for training, while the kesho mawashi is the ceremonial attire.

Points for First-Time Visitors

For beginners and foreign visitors, paying attention to the color of the mawashi makes practice easier to follow. The black mawashi marks young wrestlers in training, while the white mawashi identifies those who have achieved sekitori status.

Another point of interest is the condition of the cloth. New mawashi are stiff and less flexible, whereas well-used ones become softer and mold to the body, showing the marks of long training. Each crease and discoloration tells the story of countless practices.

Conclusion

The keiko mawashi is an essential part of sumo training. It protects the body, stabilizes movement, and strengthens the spirit. Its colors reflect rank, its material reflects tradition, and its tying method requires skill and care.

For those new to sumo, understanding the keiko mawashi provides a meaningful entry point into the sport’s culture. When visiting a training stable, observe the black and white belts, and notice how each piece of cloth carries the spirit and history of sumo.
