The term Sashimono refers to two distinct but equally fascinating aspects of Japanese history and craftsmanship. For some, it represents the pinnacle of traditional woodworking joinery, where furniture is assembled without a single nail or screw. For others, it evokes the image of the samurai, specifically the vertical banners worn on the backs of warriors to identify their clan during the chaos of battle.
Both forms of Sashimono share a common thread: precision, utility, and a deep respect for structural integrity. Whether you are a woodworking enthusiast or a history buff, understanding these two traditions offers a unique window into Japan’s cultural heritage. This guide will explore the intricacies of both the woodworking craft and the military banners to help you appreciate the skill and purpose behind them.
The Mastery of Japanese Woodworking Joinery
In the world of fine furniture, Sashimono refers to the craft of making wooden objects using complex joinery. The word itself comes from the Japanese verb sasu, which means to join or insert, and mono, meaning thing. Unlike modern furniture that relies on metal fasteners or heavy glues, Sashimono relies on the wood itself to hold the structure together.
The Philosophy of Invisible Joints
The hallmark of high-quality Sashimono is the use of “blind” or hidden joints. Craftsmen spend years mastering the ability to create mortise and tenon joints that are so precise they remain invisible from the exterior of the piece. This is not just for aesthetics; it is a practical solution to Japan’s humid climate.
Wood naturally expands and contracts with changes in moisture. Metal nails can loosen or cause the wood to split over time. By using all-wood joinery, the entire piece of furniture moves in unison, ensuring it remains stable for centuries. Many Sashimono chests, known as tansu, have survived for hundreds of years in perfect working condition.
Common Materials and Tools
Traditional woodworkers are very selective about their materials. The choice of wood depends on the intended use of the item and the desired aesthetic. Some of the most common woods include:
- Paulownia (Kiri): Highly prized for its resistance to humidity and fire. It is often used for clothing chests because it protects silk garments.
- Mulberry (Kuwa): Known for its beautiful grain and durability, often used in refined tea ceremony objects.
- Japanese Zelkova (Keyaki): A hard, heavy wood used for larger furniture pieces that require significant strength.
The tools used in this craft are as specialized as the joints themselves. Craftsmen use a variety of hand planes (kanna), chisels (nomi), and fine-toothed saws (nokogiri) to achieve the microscopic tolerances required for a perfect fit.
Regional Styles of Woodworking
Sashimono evolved differently depending on the region and the social class it served. Two primary styles emerged during the Edo period (1603–1868), each with its own distinct character.
Edo Sashimono
Edo Sashimono developed in the capital (modern-day Tokyo) to serve the needs of the merchant class and the samurai. This style is characterized by its simplicity and functionality. It emphasizes the natural beauty of the wood grain, often using clear finishes or light waxes rather than heavy lacquer. The goal is to create furniture that feels sturdy yet elegant, reflecting the practical spirit of the Edo people.
Kyo Sashimono
Originating in Kyoto, this style was developed for the imperial court, the aristocracy, and the masters of the tea ceremony. Kyo Sashimono is often more ornate and delicate than its Edo counterpart. It frequently incorporates decorative elements such as gold leaf, intricate lacquer work, or metal fittings. This style focuses on refined elegance and the philosophical principles of the tea ceremony.
The Military History of Sashimono Banners
While woodworkers were perfecting furniture, the samurai were using a different kind of Sashimono on the battlefield. During the Sengoku (Warring States) period, the Sashimono was a small banner attached to the back of a warrior’s armor. These banners were essential for identification and organization during large-scale military engagements.
Purpose and Function on the Battlefield
In the heat of battle, it was often difficult to distinguish friend from foe. The Sashimono served as a personal or unit identifier. By looking at the banners, a commander could quickly see where his troops were positioned and which units were engaging the enemy.
These banners were not just for the elite samurai; they were also worn by ashigaru (foot soldiers). While the common soldiers might wear a simple banner with the clan’s crest, high-ranking samurai might have more elaborate designs or unique shapes to signal their status and achievements.
Design and Heraldry
The most important element of the banner was the Mon, or family crest. These symbols were usually bold and simple, such as a circle, a stylized flower, or geometric shapes, ensuring they were visible from a distance. The color of the fabric also played a role in identification, with different divisions of an army wearing different colors.
- White and Black: Common high-contrast colors for maximum visibility.
- Red and Gold: Often used by elite units or high-ranking generals to signify power.
- Unique Shapes: Some warriors used three-dimensional objects, such as gourds or feathers, instead of flat banners to make themselves even more recognizable.
How Banners Were Worn
The Sashimono was attached to the back of the armor (the dou) using a specialized set of fittings. A socket was bolted to the lower part of the armor, and a ring or bracket was attached near the shoulder blades. A long bamboo pole would be slid through these fittings, holding the banner securely in place while allowing the warrior to move his arms freely in combat.
Preserving the Tradition Today
Today, both forms of Sashimono are considered important cultural assets in Japan. Traditional woodworking is kept alive by a small number of dedicated artisans who continue to produce handmade furniture using centuries-old techniques. These pieces are highly sought after by collectors who value the “quiet strength” of the joinery.
Similarly, the history of the samurai banners is preserved in museums and through historical reenactments. During festivals like the Soma Nomaoi in Fukushima, hundreds of riders carry Sashimono banners, providing a glimpse into the visual spectacle of Japan’s feudal past.
Conclusion
Sashimono represents the Japanese commitment to excellence, whether in the quiet workshop or on the battlefield. The woodworking tradition teaches us the value of patience and the hidden strength of natural materials, while the military banners remind us of the importance of identity and organization. By exploring these crafts, we gain a deeper understanding of how traditional techniques continue to influence modern design and cultural identity.
