What Is the Kashira? Japanese Sword Pommel (頭)
The kashira (頭) is the pommel cap at the butt end of a Japanese sword hilt — the small metal fitting that closes the end of the tsuka opposite the guard. Literally "head," it seals the wooden handle core, protects and finishes the end grain, and anchors the cord wrap, which is knotted through or around it. It is made as a matched pair with the fuchi (縁) collar at the guard end, and the two together are called the fuchigashira (縁頭).
For a collector, the kashira is a small but conspicuous piece of the kinko (soft-metal) artist's craft. Sitting at the very end of the grip, it is one of the first fittings the eye lands on, and its alloy, motif, and finish — read together with the matching fuchi — signal the quality, school, and coherence of the whole set of mounts.
What the kashira does
The kashira caps and protects the butt of the tsuka, guarding the vulnerable end grain of the wood core and giving the hilt a clean, finished terminus. It also secures the wrap: on most hilts the two ends of the tsuka-ito are drawn through a pair of small holes (shitodome-ana, often lined with metal eyelets called shitodome) in the kashira and tied off, so the cord binding is locked in place at the pommel. In this way the kashira is both structural closure and the finishing point of the entire wrap.
Materials and schools
The kashira is made from the same coloured soft metals as the rest of the sword furniture, worked by the kinko fitting artist:
- Shakudo (赤銅) — copper-gold alloy patinated to deep blue-black; the classic formal ground, favoured by the Goto school.
- Shibuichi (四分一) — copper-silver alloy in soft grey tones, suited to subtle pictorial work.
- Gold, silver, copper, and iron — used solid, as inlay, or as accents to carry the motif.
Every major fitting tradition produced kashira as half of a fuchigashira set — the formal Goto (後藤) lineage that served the shogunate, and the freer machibori town-carvers such as the Nara and Yokoya schools. Because the kashira is small, artists often chose a tightly focused motif — a single animal, flower, or crest — that completes the story begun on the fuchi.
Kashira and fuchi: reading them as a pair
The kashira is designed as the partner of the fuchi, not a standalone. A true fuchigashira shares one alloy, one patina, and one theme across both ends of the hilt, and finer sets are by a single hand and may be signed. When you evaluate mounts, a kashira and fuchi that clearly match confirm original, coordinated koshirae; a kashira that does not match its fuchi in metal or style is a sign the set was assembled from parts, which reduces its interest and value to a collector. Loose antique kashira — separated from their sets — are also traded on their own for their artistic merit.
Frequently asked questions
What is the kashira on a katana?
The kashira is the pommel cap at the butt end of the hilt, opposite the guard. It closes and protects the end of the wooden handle core and anchors the cord wrap, whose ends are usually tied off through small holes in the kashira.
What is the difference between kashira and fuchi?
The kashira is the cap at the butt end of the hilt, while the fuchi is the collar at the guard end. They are made and sold together as a matched pair called the fuchigashira, sharing the same alloy, finish, and decorative theme.
What is a fuchigashira?
Fuchigashira is the term for the fuchi and kashira taken together as a coordinated set — the collar at the front of the hilt and the cap at the back, made to match in metal and design. Collectors prize sets that are clearly by one hand, ideally signed, over mismatched pairs.
