Kenjutsu Cut
SubFamily剣術の切り
TraditionalTranslation: Sword Art Cuts
Overview
The Kenjutsu Cut subfamily encompasses the primary cutting techniques of classical Japanese swordsmanship, classified by their trajectory and target. [1] The major cuts include shōmen-uchi (straight downward to the centreline), kesagiri (diagonal cut following the line of a monk's kesa sash), yokogiri (horizontal cut), and gyaku-kesagiri (reverse diagonal). [1],[2] Proper kenjutsu cutting mechanics require coordination of the hips, shoulders, and hasuji (blade alignment) to deliver cuts that would cleanly bisect a target with a live blade. [2],[3]
History & Origin
Kenjutsu cutting techniques were developed on the battlefields of feudal Japan and refined through centuries of kata transmission within koryū schools. [1] Tameshigiri (test cutting on straw or bamboo targets) was practised during the Edo period to verify cutting mechanics, a tradition that continues in modern iaidō and battōjutsu. [2],[3]
Effectiveness
Kenjutsu cutting techniques use the katana's curved blade geometry and two-handed grip to deliver powerful slicing cuts capable of cutting through armour gaps, limbs, and bone. [1]
Lineage
Competition Record
Kenjutsu cutting is tested in tameshigiri (test cutting) competitions and demonstrated in koryū embu (demonstrations) at events like the Nippon Budokan Kobudo Taikai. [1]

Biomechanical Mechanism
Primary Action — Cutting, thrusting, or striking with a bladed weapon — edge alignment and trajectory determine cutting effectiveness
Joints Involved — Wrists (edge alignment and rotation), elbows (extension for thrusts, chambering for cuts), shoulders (arc of the cut), hips (power generation)
Force Vector — Varies — downward diagonal cut (kesa-giri), horizontal cut (yoko-giri), thrust (tsuki), or rising cut (kiri-age)
Weapon Mechanic — Edge alignment (hasuji) is critical — the blade must travel along its cutting plane for effective cuts
Position & Entry
From ready stance (chudan-no-kamae or equivalent) — Assume guard position, establish distance (ma-ai), execute the cut or thrust when an opening appears
From engagement distance — Use footwork to close to striking range, execute the technique with proper edge alignment (hasuji)
As counter — Wait for the opponent's attack, deflect or avoid, and counter-cut to the exposed target

FIK Kendo Competition RulesPDFTraining Notes
✓Kenjutsu cuts are the offensive foundation of Japanese swordsmanship — precise cutting techniques that use the curved katana blade with proper hasuji (edge alignment) and body mechanics (Draeger, Classical Budo, 1973)
✓The four primary kendo cuts: men (head), kote (wrist), do (body), and tsuki (thrust) — these define the target areas and cutting paths
✓Japanese cutting mechanics are unique: the katana's curve requires a pulling action (hikitsuke) at the moment of impact to achieve effective cutting
✓Tenouchi (grip squeezing) at the moment of impact is the key to effective cutting: the hands squeeze to accelerate the blade through the target
✓The concept of 'hasuji' (edge alignment): the cutting edge must be perfectly aligned with the direction of the cut for the blade to cut effectively
✓Tameshigiri (test cutting) on rolled tatami mats or bamboo provides feedback on cutting technique that cannot be obtained from air cutting alone
✓The katana is a two-handed weapon: the left hand provides power at the base of the handle, the right hand provides direction near the guard
Common Mistakes
!Cutting with arm strength — Japanese cutting uses hip rotation, core engagement, and tenouchi for power
!Poor hasuji (edge alignment) — the edge must be aligned with the cut direction; misalignment causes the blade to bounce or turn
!Using the same grip pressure throughout the cut — the grip tightens only at the moment of impact (tenouchi)
!Not following through the cut — the blade must travel through the target, not stop on contact
!Cutting without hip rotation — the hips generate the power that the arms transmit to the blade
!Raising the sword too high before cutting — the preparatory movement should be minimal; excessive wind-up is telegraphing
!Not training tameshigiri when possible — test cutting provides essential feedback on cutting mechanics

Do Cut
GenusThe Dō Cut targets the opponent's torso with a diagonal or horizontal cut to the midsection, one of the four primary target areas in both kenjutsu and kendō. [1] The dō cut requires precise blade angle to connect with the relatively flat surface of the torso, and in kendō it demands a distinctive follow-through where the striker passes to the side after contact. [1,2] In kenjutsu the dō cut is valued as an effective attack against opponents who raise their guard high, exposing the midsection. [2,3]
Explore
Kote Cut
GenusThe Kote Cut targets the opponent's wrist or forearm, striking the area just above the hand to disable the opponent's ability to wield the sword. [1] In kendō, the kote strike targets the right kote when the opponent is in chūdan-no-kamae, requiring less travel distance than a men strike and making it one of the fastest attacks. [1,2] In kenjutsu the kote cut was a primary battlefield strategy for disabling an opponent without requiring a lethal blow, and it is frequently scored as a counter-technique when the opponent initiates an overhead attack. [2,3]
Explore
Men Cut
GenusThe Men Cut is a descending vertical or slightly diagonal cut to the top of the opponent's head, the most fundamental and frequently practised technique in Japanese swordsmanship. [1] A correct men cut requires raising the sword above the head, driving it downward with snap of the wrists (tenouchi), and in kendō executing fumikomi with the right foot and passing through the opponent — all unified with a spirited kiai. [1,2] The men cut is the first technique taught to beginners in both kenjutsu and kendō and the most commonly scored ippon in competition at all levels. [2,3]
2 species·2 techniquesExplore
Tsuki Thrust
GenusThe Tsuki Thrust targets the throat protector (tsuki-dare) of the men with a straight forward thrust of the shinai tip, making it the only non-cutting technique among kendō's four scoring actions. [1] Tsuki is the most dangerous technique in kendō due to the risk of injury if misdirected, and it is therefore restricted in competition — generally permitted only for adults at dan-grade level. [1,2] A valid tsuki must contact the tsuki-dare squarely with the kensen (sword tip) while demonstrating full body commitment and zanshin. [2,3]

Frequently Asked Questions
Should I practice the kenjutsu drop cut standing up or in seiza position?
While standing is simpler, Channel8TGN emphasizes that staying in seiza position with your knees underneath you and a strong back is harder but essential for consistency—it allows you to strike more easily and establish proper rhythm over time with practice.
What height should I hold the target object before dropping it?
Channel8TGN recommends holding the object at eye level before dropping it. If you hold it too high or too low, you won't hit it consistently because you'll be taking your hands to different levels rather than focusing on the object itself.
How should I position the sheath in my belt for the drop cut?
Channel8TGN advises pulling the saiya (sheath) way back over to your left hip and turning it flat to the ground. Keeping the sheath too far out may feel comfortable but will prevent you from drawing the sword as far as needed.
What objects can I use to practice drop cutting?
Channel8TGN suggests starting with simple household items like a tennis ball, bean bag, empty water bottle, or rolled-up sock, or a wooden dowel about 24 inches long—all are effective for learning the technique.
