The Work of a Tate-shi — How Sword-Action Is Created for Period Dramas

What Is Tate? — The Aesthetic of Battle Expressed Through "Kata"

The sword fights seen in period dramas and sword-fighting films are not the actors actually striking blades against each other. By safely performing a prearranged sequence of movements — known as "kata" — the production creates the effect of a gripping, real-life duel for the audience. The specialist who designs this choreography and trains the actors is called a tate-shi. Even fans who have watched many works featuring nihontō often watch without knowing what this profession does on the other side of the screen.

Tate is not a simple combination of movements. It is built on a meticulously calculated blueprint that encompasses the distance between blades, body orientation, footwork, and the spatial sense needed to stop a blade just short of touching an opponent. The more spectacular the fight sequence, the more thorough the preparation that underpins it tends to be. Actors commit dozens of movements and their intervals to muscle memory — just as they memorize lines — before stepping in front of the camera.

The Origins of the Tate-shi Profession — Hayashi Kunishirō and "Wakakoma"

The tate-shi as a specialized profession became established during the golden age of the Shōwa film and television industry, when period dramas were produced in large quantities. Initially, it was common practice for a specialist in a particular martial art to be called in individually each time a scene required that discipline to be recreated.

The figure who most changed this situation was Hayashi Kunishirō. In 1965, at the age of 25, he served as tate-shi for the NHK taiga drama "Taikōki" and simultaneously founded Wakakoma, Japan's first stunt performer group. Holding the conviction that "a tate-shi should study genuine martial arts," Hayashi traveled to practitioners of various kenjutsu schools, jūjutsu, Ryukyu kobudō, taijiquan, and other traditions, incorporating authentic combat techniques into his tate. From that point on, the tate-shi became established not only as an acting coach for performers but as a specialist bridging martial arts and screen expression.

Before this period, specialists in kenjutsu, iai, jūjutsu, and other disciplines were called in separately for each fight scene, and it was rare for tate to be constructed under a unified directorial vision. The significance of martial artists themselves transitioning into a specialized profession dedicated to systematizing tate cannot be overstated — it made it possible to sustain a consistent aesthetic of "kata" throughout a single work.

The Design Philosophy of Tate — Balancing Safety and Convincing Authenticity

The highest priority in a tate-shi's work is safety management: ensuring that no injuries occur despite the use of replica swords, which are inherently dangerous props. At the same time, they must achieve a level of convincing authenticity that makes audiences feel they are watching a real sword fight.

Several common techniques characterize the tate constructed on set. During rehearsal, the tate-shi typically begins by partnering with the actor to work through the kata, confirming not only the sequence of movements but also the timing of breathing, before gradually increasing speed.

• Without actually making blade contact, create the illusion of a "cut" through eye line, distance, and timing
• Design the movement path to suit the camera's angle of view, routing dangerous trajectories to positions invisible to the audience
• Adjust the difficulty of the kata to match the actor's physique and experience, drilling it into the body through repeated rehearsal
• Use replica swords that reproduce the weight and sori of the actual blade, lending the movements a convincing authenticity close to the real thing

Through this accumulation of technique, a single replica sword can generate greater tension on screen than a real nihontō. On set, a live nihontō is almost never used; instead, purpose-built replica swords whose balance and blade length match the real article are employed. This serves not only to protect the safety of actors and staff but also, for practical reasons, to eliminate the risk of chipping or warping no matter how many retakes are required.

From Stage and Screen to Motion Capture — An Expanding Field of Activity

The tate-shi's field of activity is not limited to jidaigeki films and television dramas. In kabuki and popular theater, and in recent years in motion-capture recording for game production, tate-shi have come to serve as supervisors of sword action. Whatever the medium of expression, the essential role — lending convincing authenticity to the way a sword is handled — remains unchanged.

In the case of screen productions, tate is designed as an integrated whole with the editing's cut structure and camerawork, not just the actor's individual performance. Before a single sword-fight scene is complete, there is an accumulation of collaborative work by multiple specialists: the actors drill the kata the tate-shi has constructed, the director and director of photography adjust the movement paths, and stunt performers take over for the more dangerous portions. The lineage of nihontō depiction in film is also discussed in Swords in Film.

Knowing the Real Sword Changes How You See Tate

The convincing power of the choreography a tate-shi creates is underpinned by their study of real nihontō and the principles of classical kenjutsu schools. Conversely, if you know the weight, sori, and balance point of actual nihontō, you will be able to appreciate on a deeper level why the tate in a film looks so beautiful. Whether it is a kata using a tachi — with its large, sweeping overhead swing — or the swift draw-cut of an uchigatana, the type of sword fundamentally changes the distance and the very quality of movement in the tate; this is another point of appreciation that only those who know the real thing can notice. Knowing the surrounding knowledge of nihontō culture can change the very way you view screen works.
