Sageo: Types, Functions, and Carrying Traditions—Materials, Colors, and School-Specific Tying Methods

What Is Sageo—Decorative Cord Developed as a Portable Accessory for Japanese Swords

"Sageo" (下緒) refers to braided silk cord or leather cord attached to the saya of a Japanese sword, which is threaded through a hole or loop called the "sageo-tōshi" located near the "koijiri" on the saya. The name derives from "cord that hangs below," coming from the fact that when the sword is thrust into the belt, the excess cord hangs down from the lower part of the saya.

Sageo was not merely a decorative element but played an important functional role in carrying, securing, and drawing the sword. Moreover, the material, color, and method of tying were precisely regulated depending on the warrior's school, social status, and whether the occasion was formal dress or the battlefield. As part of the sword fittings (koshirae), it has been highly valued for its aesthetic worth.

Materials and Types of Sageo

Sageo materials are broadly classified into two types: braided silk cord (kumihimo) and leather.

Silk braided cord (kumihimo) is considered the most formal material. Braided cord hand-assembled by craftsmen using pure silk requires uniform thickness, luster, and color, and its production requires high-level skill. During the Edo period, cord makers in Kyoto supplied high-quality sageo and met the demands of the samurai class. Depending on the braiding method, there are various types such as "marugumi" (round braid), "hiramuchi-gumi" (flat braid), "kakugumi" (square braid), and "Edo-uchi" (Edo braid), each used appropriately depending on the occasion and school of martial arts.

Leather sageo, made from thin-cut deer or cow hide, was valued for its durability and practicality. It was used in battlefield conditions and paired with rough-styled fittings, possessing a simple yet functional appeal.

Hemp sageo, being relatively inexpensive and readily available, was used for daily samurai wear and on the swords of ashigaru (light foot soldiers) and common soldiers.

Color and Meaning of Sageo

The color of sageo functioned as an important symbol indicating a warrior's social status, school, and whether the occasion was formal dress. While color usage varied by school and era, several representative conventions have been passed down.

Indigo (kon) was the most common color, widely used for everyday samurai sword wear. The subdued hue was said to express samurai dignity. Brown (cha) and black (kuro) were also used for everyday wear and were valued as understated yet dignified combinations. White (shiro) was used for formal dress and ceremonial fittings, treated as a color symbolizing purity and cleanliness. Red (aka) was sometimes used for formal samurai dress and auspicious occasions; moreover, some schools used distinctive colors as a means to identify their disciples.

School-Specific Conventions for Tying Methods

The method of tying sageo was variously prescribed by different schools, and it was even said that "if you see a kenjutsu school, you can tell by how the sageo is tied."

Sageo handling in iaido is particularly emphasized. In iaido's drawing technique, the crucial point is how quickly one can draw the sword from its saya, and specific tying methods are established so that the sageo does not impede the draw. In major iaido schools (such as Muso Shinden-ryu, Musō Jikiden Eishin-ryu, and Tamiya-ryu), the method of handling sageo during practice is detailed in regulations and is one of the matters transmitted to disciples.

As for sageo use in martial strategy schools, some schools have transmitted techniques of employing sageo as a weapon. There exists "sageo-jutsu," a technique in which a long sageo (approximately 3-4 shaku in length) is used in combination with the sword, with various applications such as entangling and capturing an opponent, disarming weapons, or binding up in urgent situations.

Contemporary Choice of Sageo and Cultural Significance

For contemporary Japanese sword enthusiasts, iaido practitioners, and sword collectors, the choice of sageo is an important element that determines the aesthetic completion of the sword fittings. Selecting sageo appropriate to the era, school, and purpose is essential in establishing the overall "elegance" of the sword.

High-quality braided cord sageo is still crafted by traditional cord makers, with specialist cord shops centered in Kyoto and Tokyo remaining active. Both pure silk and synthetic fiber materials are used, with prices ranging widely from several thousand to tens of thousands of yen.

Although sageo is an often-overlooked detail in Japanese sword culture, the combination of its material, color, and tying method becomes eloquent evidence of the overall cultural context of the sword. When appreciating and studying the Japanese sword not merely as a blade but as a comprehensive cultural product, we hope you will also pay attention to the sageo.
