Building Your Own Custom Koshirae and Samurai Daisho
Overview:
When sourcing swords for our clients, we often acquire swords without koshirae the traditional Samurai fittings that prepare the sword for battle. Many top-quality swords are in fact housed only in a beautiful custom-made shirasaya (white scabbard).
There are a couple main reasons for this:
The Japanese sword and other weapons were banned from public wear during the Meiji period in 1876 with the fall of the Samurai class. This edict was called Haitorei. Demand for custom fittings meant for a Japanese sword naturally declined significantly.
Koshirae that does exist from the Edo period (pre-1868) are often found not in great shape. The first thing to suffer is the silk wrapped on the hilt. It will naturally fray after a few decades. The rayskin under the silk will also dry up and crack. Furthermore, the scabbard, which is made of wood and lacquered, can be found damaged and weakened if neglected.
Therefore, it is increasingly difficult to find koshirae that still exists in excellent condition.
Thankfully with the passion and enthusiasm of our clients, we’re building traditional koshirae for marvellous antique Samurai swords.

What exactly is a shirasaya?
A shirasaya, literally “white scabbard”, is a wooden Japanese blade mount consisting of a saya (scabbard) and tsuka (hilt), traditionally made of made of honoki (magnolia wood) – a type of wood generally found only in Japan.
A shirasaya is like a pair of pyjamas, or sleeping wear for the Japanese sword. When not carried in public or on the battlefield by their Samurai owner, Japanese swords are rested and kept protected in their shirasaya. Therefore, Japanese swords are meant to have two sets of furniture; one set for resting, and one for battle or daytime use.
The need for an actual specialized storage device was because prolonged koshirae mounting actually harmed the blade, owing to factors such as the lacquered wood retaining moisture and encouraging corrosion. A shirasaya is custom-made to the sword matching its exact length and curvature by a skilled craftsman. It allows the sword to “breath”.
A Custom Koshirae Project: Where Modern life meets tradition
A custom koshirae involves blending elements from the Edo-period (pre-1868) with modern-day craftsmanship.
The great news is that the tsuba (guard), the fuchi-kashira (collar/pommel) and menuki (grips under the silk on the hilt) can be all be sourced from the 19th century and earlier. They are made from a variety of soft metals such as shakudo or shibuichi to good-ole iron. They will live on and on.
The tsuka (hilt) and saya (scabbard) will be crafted from scratch to the exact dimensions of the sword by a modern-day artisan using traditional techniques.
**Note: The craftsman needs the sword to craft the hilt and scabbard. We sometimes get requests for a koshirae to be produced without the sword, but this is just not possible.
A Rewarding Project
A custom koshirae project is very rewarding because just like a Samurai, you can put your own personal stamp on the sword. Samurai (especially high-ranking Samurai) often had a number of koshirae made for their favourite swords and occasions (battle, formal wear, etc.).
Plus by creating a koshirae, we are supporting the modern-day craftsmen and women that carry on these marvellous handmade centuries-old traditions. Several hours of full concentration and attention to detail are put into the making of each koshirae.
Cost and Timeframe
The cost to make a custom koshirae generally ranges from 250,000 yen to 500,000 yen ($2,500 to $5,000). The main driving factor in determining the final price are the individual pieces that make up the koshirae. Antique fittings generally cost more than those made today.
This is especially true for fittings that are signed and/or have NBTHK or NTHK-NPO conservation certification.
A custom koshirae project takes about 3-6 months to complete.
Building Your Own Custom Daisho
A particularly special project that we recommend is to build your own custom daisho (matching katana and wakizashi). The daisho was the official dress code of the Samurai during the Edo period. It was rigidly enforced from 1626 to 1868.
Visually speaking, there is nothing quite like the impressiveness of an authentic daisho on display in a home or office. It exudes a feeling of majesty and calmness.
Steps to building Your Daisho:
Step 1. A close discussion is had with the client to confirm project aspirations. Matters such as the type of sword combination, the theme of fittings and overall budget is shared.
Potential sword options that are in stock (often not listed in the catalogue) are presented to the client in person or images via email.
Step 2. We source and secure a katana and wakizashi that compliment each other. Commonality could be that the swords are by the same swordsmith, from a similar time period (or vastly different time periods), by the same school or tradition, etc. Overall we always seek a grand visual balance with a story to tell.
Full payment (or deposit with longer-term payment plan) for the swords is made in advance.
Step 3. We source matching Edo-period daisho-specific fittings of a chosen theme that the client feels a personal connection with. We can also source fittings that are very similar in design or create modern fittings too.
Client decides on a matching colour and style for the scabbards. A common colour is also selected for the tsuka-ito (silk or leather wrap for the hilts).
Step 4. Photos and prices of potential fittings are shared with the client in advance. Once client has given full approval of the fittings, we build the daisho. This takes about 3-6 months.
Note: Producing matching scabbards lacquered in traditional black (such as the photo above) is often quicker to produce.
Step 5. Upon completion of the daisho, final payment is made for the koshirae production. We then securely ship the swords to you. Congratulations!!
Daisho Production Cost
The cost to produce a genuine Samurai daisho ranges. Generally speaking, the completed production cost of two antique swords with matching daisho fittings starts at around $25,000.
The investment into a pair of swords by a celebrated swordsmith(s) with a high degree of NBTHK or NTHK-NPO origami certification will be greater, but always worthwhile.
