Hasso No Kamae

Genus

八相の構え

Traditional

Translation: Eight-Phases Stance

Overview

Hassō-no-kamae (eight-direction guard) positions the sword vertically beside the right side of the head, with the tsuka at mouth height and the blade pointing upward. [1] This guard radiates threat in all eight directions (hence its name) and is an aggressive posture that facilitates rapid downward and diagonal cuts. [1],[2] Hassō-no-kamae is associated with the element of fire (ka) and is used in kenjutsu to pressure the opponent with the implied threat of explosive cutting from a high position. [2],[3]

History & Origin

Hassō-no-kamae is one of the five traditional kamae in Japanese kenjutsu, described in numerous koryū manuscripts and in Musashi's Book of Five Rings as the fire guard. [1] It is practised in both koryū kata and in the Nihon Kendō Kata of the AJKF. [2],[3]

Effectiveness

Hasso no kamae (eight-direction guard) positions the shinai upright beside the right shoulder, with the tsuba (guard) near mouth level. [1] It is a compact guard used primarily in kendo kata rather than in free sparring (jigeiko), valued for its ability to transition quickly into both cuts and thrusts. [2]

Lineage

Hassō no kamae holds the sword vertically beside the head, a classical kenjutsu guard that appears in kata but is rarely used in free sparring. [1]

Competition Record

Hassō no kamae is practised in kendo kata but is virtually never used in free kendo competition (shiai). [1]

Biomechanical Mechanism

Primary ActionCutting, thrusting, or striking with a bladed weapon — edge alignment and trajectory determine cutting effectiveness
Joints InvolvedWrists (edge alignment and rotation), elbows (extension for thrusts, chambering for cuts), shoulders (arc of the cut), hips (power generation)
Force VectorVaries — downward diagonal cut (kesa-giri), horizontal cut (yoko-giri), thrust (tsuki), or rising cut (kiri-age)
Weapon MechanicEdge 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 distanceUse footwork to close to striking range, execute the technique with proper edge alignment (hasuji)
As counterWait for the opponent's attack, deflect or avoid, and counter-cut to the exposed target

Variants

Standard cutprimary cutting angle from the ready stance
Thrust (tsuki)straight thrust targeting the throat, chest, or face
Rising cut (kiri-age)upward diagonal cut from low to high
Diagonal cut (kesa-giri)downward diagonal cut following the kimono line

What Instructors Say

Hasso no kamae is a classical Japanese sword stance appearing in historical Shinkagekyu documentation, particularly the Yagyu Shinkagekyu manuscript tradition dating to approximately 1600, with illustrated descriptions circa 1700. According to Antony Cummins, the stance positions the sword roughly at mid-height near the head, though Cummins presents a nuanced historiographic analysis noting discrepancies between textual descriptions and pictorial representations in original scrolls, suggesting possible hand variations or left-sided (hidaritachi) positioning in certain lineage transmissions. Cummins cites evidence from kata descriptions indicating hasso no kamae functions as both an offensive posture from which to strike downward and a defensive position into which one retreats when threatened by overhead attacks from an opponent also in hasso. He theorizes the stance may involve rhythmic footwork and beat-based exchanges rather than purely static positioning, drawing parallels to competitive fencing exchanges. The instructors emphasize that hasso no kamae's practical application involves responding to attacks on the sword tip by withdrawing slightly and executing downward cuts, and that the stance relates to broader systematic movement principles documented in classical kenjutsu curricula. Cummins notes historical ambiguity persists regarding whether pictorial representations depict starting positions, ending positions, or intermediate moments within techniques.

Training Notes

Hasso no Kamae (eight-phase stance) holds the sword upright beside the right shoulder with the blade facing forward — it is a versatile stance used in classical kenjutsu for offensive and defensive purposes (Draeger, Classical Budo, 1973)
The name 'eight phases' refers to the ability to attack in eight directions from this position: the stance loads cuts to all angles
Hasso is held with the sword vertical, the tsuba (guard) at face height, and the blade facing forward — the cutting edge faces the opponent
From Hasso, the primary cuts are: horizontal (yokomen), diagonal descending (kesa), and the men (vertical head cut) — each can be delivered rapidly
Hasso is more common in classical kenjutsu than in modern kendo: the classical schools use it for its versatility and deceptive quality
The stance resembles the position of a warrior at rest: compact, guarded, and ready — the sword is close to the body and protected
Hasso transitions naturally to all other kamae: the upright sword can drop to Chudan, rise to Jodan, or descend to Gedan with equal ease

Common Mistakes

!Holding the sword too far from the body — the sword in Hasso should be close to the right shoulder for compact readiness
!Facing the blade away from the opponent — the cutting edge must face forward for quick deployment
!Holding Hasso with the sword tilted — the blade should be vertical or near-vertical
!Using Hasso in modern kendo competition — it is primarily a classical technique; understand the context
!Not training cuts from Hasso to all angles — the stance's value is its versatility; develop attacks in all eight directions
!Tensing the shoulders while holding Hasso — the compact position should be relaxed and ready
!Not understanding Hasso's transitional role — it is a versatile hub that connects to all other stances
