Types and Roles of Tōbukuro — the History and Modern Uses of Cloth Carrying Bags for Japanese Swords

Tōbukuro are cloth bags used for carrying nihontō, and they are tools that have long been used as part of sword culture alongside the koshirae (mounting) and the blade itself. Attention tends to focus on the beauty and provenance of the sword itself, but tōbukuro used to protect and carry it also come in a wide variety of types and roles depending on their material, construction, and purpose. Although they appear to be unassuming tools at first glance, tōbukuro are deeply connected to the etiquette of warrior households and everyday sword management, and tracing their history provides a clue to understanding the depth of nihontō culture. This article organizes the types and historical background of tōbukuro as well as their role in the modern era.

The Position of Tōbukuro — a Tool between the Saya, Koshirae, and Storage Implements

Tōbukuro are cloth bags that wrap the entire sword as housed in its saya (scabbard), protecting it from the outside air, dust, and impact during transport or temporary storage. Their role differs from that of the saya (scabbard), which directly houses the blade, and the koshirae (mounting), which is the complete sword furniture including the saya; tōbukuro serve purely as an auxiliary tool used during carrying and transport.

For long-term storage, paulownia boxes with excellent breathability are often used, and tōbukuro have functioned as tools specialized for everyday carrying and short-term storage situations. Wrapping the sword so as not to damage the koshirae (mounting) while also concealing the contents from outward appearance — this combination of practicality and propriety is one of the reasons tōbukuro have been used for so long.

Classification by Material — Brocade, Silk, Cotton, and Synthetic Fiber

The materials used for tōbukuro have long been chosen according to purpose and formality.

• Silk textiles such as nishiki (brocade) and donsu (satin damask): Used in formal occasions or for presentation gifts. Characterized by splendid patterns woven with gold and colored threads, the tōbukuro itself carries meaning as an item demonstrating the gift-giver's propriety and sincerity.
• Cotton cloth: Durable and easy to handle, widely used for everyday use and for wrapping practice swords. Because it is easy to wash and repair, it is more valued than silk textiles in situations that prioritize practicality.
• Synthetic fiber and blended materials: Materials with enhanced durability and water resistance, distributed for the purpose of transporting swords to modern practice sessions and exhibitions. They are lightweight and easy to handle, with a variety of specifications including nylon and synthetic velvet.

Since silk textile bags are prone to wear and fading, the practice of using cotton or synthetic fiber bags for situations requiring frequent removal and insertion, and silk textile bags for formal gifts and exhibitions, has long been carried out.

Types by Use and Shape — Carrying Bags, Inner Bags, and Practice Bags

Tōbukuro also differ in shape and construction depending on their use.

Carrying bags (outer bags) are general-purpose tōbukuro that wrap the entire sword with its koshirae (mounting), and often take the form of drawstring pouches with a cord-tied opening or a shape with a handle at the top. When going out or traveling, they cover the entire saya (scabbard) to prevent scratches and dirt, and are used to protect the sword when it is not being worn at the hip.

Inner bags (uchibukuro) are thin bags that wrap around the blade and saya (scabbard) to assist with storage in paulownia boxes. They serve to fix the sword in place so it does not shift and become scratched inside the box, and are often made from soft silk or cotton cloth. They may be called tōbukuro or tōfu, and there is no unified standard for the use of these names.

Practice bags are practical bags used when bringing swords to the dojo for iai and tameshigiri practice. Some have straps for carrying over the shoulder or are made large enough to hold multiple swords at once, with materials and shapes chosen to prioritize functionality.

The Culture of Carrying Swords in Warrior Society and the Etiquette of Tōbukuro

The background to tōbukuro acquiring etiquette-related significance lies in the position of the sword in warrior society. For warriors, the sword was both a symbol of status and a tool carried in daily life, so a certain level of formality was demanded not only of the sword itself but also of the conduct and accessories associated with handling it.

When presenting a sword as a formal gift, etiquette extended to the type of textile, color pattern, and manner of tying the cord of the bag, and there were occasions when tōbukuro held ceremonial significance beyond being mere practical items. The material and design of the bag were sometimes chosen according to the formality of the giver and the nature of the relationship with the recipient, and it is thought that the entire set of accessories surrounding the sword formed part of the etiquette system of the warrior class.

The formality of the tōbukuro was also not irrelevant when carrying swords to official occasions such as sankin-kōtai or attendance at a castle. This shows that sword culture was established not only through the kaji (smithing) techniques of the blade but also through the system of conduct, etiquette, and accessories surrounding it.

Care and Storage Precautions for Tōbukuro

Because tōbukuro are made of cloth, improper handling can have an adverse effect on the sword itself. By paying attention to the following points, it becomes easier to keep tōbukuro clean for a long time and to maintain the condition of the sword stored within.

1. Shade-dry after use: If a bag that has absorbed moisture during carrying is stored in a sealed state, the moisture remaining in the cloth can affect the saya (scabbard) and blade. The basic practice is to remove the bag after use and dry it in a shaded, well-ventilated place.
2. Be careful of oil stains: Chōji oil and rust-prevention oil used in blade maintenance can soak through the saya (scabbard) into the bag. Since the accumulation of oil in the cloth accelerates material degradation, particular care is needed when using it as an inner bag.
3. Transfer to a paulownia box for long-term storage: For long-term storage, it is advisable to remove the sword from the tōbukuro and transfer it to a paulownia box. Paulownia is said to have moisture-regulating and insect-repelling properties, and it is easier to create a more stable storage environment than relying on a cloth bag alone.
4. Avoid friction with nishiki and silk bags: Bags made from luxury materials have delicate fibers and are prone to wear and fading from frequent insertion and removal. For everyday use outside of formal occasions, switching to durable cotton or synthetic fiber bags helps protect both the bag and the sword.

The Significance of Tōbukuro in the Modern Era

Even today, tōbukuro remain familiar tools for those who own swords. Their practical roles — carrying to exhibitions and practice, keeping off dust during storage, protecting swords during moves and transport — remain unchanged.

On the other hand, tōbukuro made from traditional nishiki (brocade) and donsu (satin damask) can have value as craft objects in the same way as the swords themselves, and old tōbukuro sometimes become objects of collection. Bags made using weaving techniques from before the Edo period are sometimes appreciated as decorative craft objects independent of the sword, offering a glimpse into the world of craftsmanship that extends around sword culture.

Expanding one's perspective beyond the kaji (smithing), polishing, and koshirae (mounting) of the sword itself to peripheral tools such as tōbukuro provides a clue to understanding how carefully nihontō have been handled over the long years.
