What are Togishi? — The Final Craftsmen Who Determine a Sword's Beauty
In the process of Japanese sword creation, while the sword smith (sword forger) hammers steel to create the sword's shape, the togishi (sword polisher) is a specialized craftsman who polishes the blade and brings it to its final aesthetic state. No matter how masterfully a skilled sword smith forges a renowned blade, if the togishi's skill is lacking, the sword will not achieve its true value. Conversely, in the hands of an excellent togishi, even an outwardly modest sword can have its latent beauty drawn out to the fullest.
The work of the togishi is not mere "polishing." It is the crystallization of highly refined sensibility and technique — optimizing the form of the hamon, its action, the landscape of the jihada, and the appearance of the utsuri through precise control of the type of whetstone, polishing angle, and the subtle pressure applied.
Types of Whetstones and Polishing Stages — From Rough to Finish
The work of the togishi is broadly divided into two stages: "base polishing (shitaji-togi)" and "finish polishing (shiage-togi)."
In base polishing, the togishi progresses from coarser whetstones to finer ones, adjusting the overall shape of the blade and removing forging marks. The principal whetstones used are as follows:
- Rough whetstone (arato): The coarsest whetstone, used for correcting blade deformation, removing large rust and deep scratches. Artificial whetstones are often used.
- Medium whetstone (nakato): A whetstone that removes scratches made by the rough whetstone while bringing the blade surface closer to smoothness. This is the stage where controlling the direction of polishing marks becomes critical.
- Fine whetstone (hosoto): The flatness of the blade surface increases, and the patterns of the jihada (itame, mokume, masame, etc.) begin to become visible.
Finish polishing is the stage that embodies the true essence of the togishi's work, and the choice of whetstone and technique used determine the final appearance.
- Inner cloud whetstone (uchigumori-to): A natural whetstone from Kameoka, Kyoto, that produces a finish with uniform "cloudiness" across the entire blade. The choice and handling of this whetstone directly demonstrates the togishi's level of expertise.
- Blade luster (hatsuyaki): A thin whetstone fragment used in the final stage of finish polishing, employed to emphasize the action of the hamon (nie and nioi). This work determines the "brilliance" of the hamon.
The Difficult Technique of Drawing Out Utsuri — Dialogue Between Hamon and Jihada
One of the technical peaks of togishi skill is drawing out "utsuri" (reflections). Utsuri is the whitened shadow that appears within the jigane in correspondence with the hamon, particularly common on Bizen-den swords. This utsuri lies dormant in the jigane during the forging process, and the togishi "brings it out" through polishing technique.
To draw out utsuri, fine adjustments of polishing angle and pressure specialized for appreciating the jihada are necessary, requiring a different approach than the polishing method prioritizing appreciation of the hamon. A skilled togishi possesses the eye of a connoisseur, asking "where should this sword be shown now?" and adjusting the polishing method accordingly.
Utsuri comes in the following types, and expressing each type to its fullest requires a corresponding polishing approach:
- White utsuri (shiro-utsuri)
- Rod utsuri (bo-utsuri)
- Turbulent utsuri (midareutsuri)
Types of Jihada and Polishing — Approaches for Each Pattern
Jihada is the pattern of forge-welding lines that appear on the jigane surface, formed by the sword smith's forging technique and the steel's properties. The togishi discerns the type of jihada and selects the optimal polishing method.
| Jihada | Characteristics | Polishing Method |
|---|---|---|
| Itame jihada | The most common jihada, characterized by flowing patterns resembling the grain of wood | Polishing evenly with an uchigumori whetstone tends to reveal the greatest beauty |
| Mokume jihada | Rounded spiral patterns resembling wood burls, commonly seen on Bizen-den swords | Requires extremely gentle polishing to avoid destroying the surface "landscape" |
| Masame jihada | A jihada pattern unique to Yamato-den swords, flowing straight in the vertical direction | Polishing along the direction of the masame is fundamental; polishing against it will cause the jihada lines to collapse |
| Ayasugi jihada | A distinctive zigzag pattern found in the Gatsuyama school, one of the most technically difficult jihada types | Its expression requires specialized experience, and togishi skilled in this are considered rare assets within the industry |
Hatsuyaki Finish — Maximizing the Action of the Hamon
The culmination of the togishi's work is the hatsuyaki finish. Hatsuyaki is a small whetstone fragment manipulated with fine movements along the hamon while held with the fingertips, bringing the action within the hamon (nie, nioi, ashi, and ha) into sharp relief.
"Nie" is the granular luster that appears within the hamon, a visualization of subtle differences in carbon concentration. The togishi maximizes the three-dimensional quality of the nie granules by varying the angle of the hatsuyaki application. "Nioi" is finer than nie, appearing as haze-like bands of light. To make nioi beautiful requires precise control of the angle and direction of the hatsuyaki application.
Hatsuyaki finishing is a patient work that can take many hours on a single blade, and in some cases, several days.
The Path to Becoming a Togishi — Apprenticeship and Credential System
To become a togishi, like sword smiths, one must apprentice under a master and undergo long-term training. Generally, an apprenticeship period of 5 to 10 years is standard, but it is not uncommon for more than 10 years to pass before one is recognized as a fully competent togishi.
There is a "togishi technique preservation holder" system recognized by the Agency for Cultural Affairs, and togishi with particularly exceptional skill may be designated as holders of Important Intangible Cultural Property (Living National Treasures). The following are known as Living National Treasures in the field of sword polishing:
- Honami Nisshū
- Ono Kōkei
- Fujishiro Matsuo
- Nagayama Kokan
- Honami Kōshū
Togishi compensation varies greatly depending on the quantity and quality of work and the client's needs. General polishing fees typically range from tens of thousands to hundreds of thousands of yen per sword, and when seeking polishing by a renowned togishi, the cost can exceed one million yen.
Conclusion — The Togishi as a Prerequisite for Appreciation
When speaking of the beauty of Japanese swords, the existence of the togishi cannot be omitted. The togishi makes visible through polishing technique the latent beauty created by the sword smith. In the moment a collector is moved by a single sword, the work of the togishi is invariably present.
When acquiring a fine blade, confirming the polishing history from a trustworthy togishi and, when necessary, commissioning re-polishing contributes to the proper continuation of Japanese sword culture. The togishi is likewise an indispensable cultural custodian supporting the sword as a "total art form."
