Soujiyi – Learn the Iconic Katana Style

Soujiyi, an ancient Japanese swordsmanship martial art, focuses on developing both effective combat techniques and virtues like honesty and respect. Students take lessons from an experienced instructor until the techniques become part of their routine.


The legendary sword of feudal Japan (1185-1600), as used by samurai warriors through to Edo period (1603-1868), the katana represents an intricate combination of artistry, craftsmanship and utility. More than just a weapon for war though, the katana held spiritual meaning for many people as an object with spiritual importance.

Crafting a katana begins with forging tamahagane steel made of iron sand and charcoal in a clay tatara furnace. Once formed, this blade undergoes heat treatment known as yaki-ire which transforms it into hardened edge metal while maintaining a softer spine for easy cutting action.

Once forged, katana must be sharpened and polished using successively finer stones by a togishi polisher to refine its distinctive hamon and grain patterns and sharpen its edge razor sharp. When completed, its scabbard and hilt are assembled. Regular inspections should take place to ensure its integrity and functionality.


Samurai were Japan’s elite warrior class. This special style involved carrying two swords simultaneously: the longer katana and shorter wakizashi. Their unique dual-wielding style inspired hundreds of fighting techniques; only those proven effective survived. Additionally, these warriors also created kata, or predetermined sequences of movements and strikes which simulate combat scenarios.

Muso Jikiden Eishin-ryu, a branch of Kenjutsu, emphasizes Iaido to develop simultaneous draw and cut techniques characteristic of Samurai combatants. This style cultivates spiritual harmony along with battlefield skill; sitting or standing techniques may be employed as well as combat against multiple opponents.

Samurai warriors used sword training techniques such as cutting through targets made of straw or bamboo mats and animal carcasses to test their blade’s sharpness and strength. Iaijutsu teaches modern practitioners to pursue precision and mastery by engaging in structured practice under an experienced instructor, harmonizing body and mind through training with wooden swords such as the bokken (wooden swords) or aluminum copies (iaito) as a means of improving physical prowess; additionally they utilize techniques called “tameshigiri,” whereby target materials are sliced through target materials to improve accuracy and blade angle.


The Katana was not simply a weapon for Samurais – it also symbolized their spirit and honor. No Samurai would leave home without their sword in hand and spent hours practicing and meditation to ensure that it remained sharp, clean, and ready for battle.

Swordsmiths dedicate themselves to crafting each katana with intense concentration and hard work, fusing carbon with metal to craft durable yet robust blades capable of withstanding intense cutting sessions.

A katana has many distinctive features, one being its Sori, or curvature. To determine its Sori, measure from Munemachi to Kissaki or tip and take measurements from these points. A Bohi groove may also help reduce weight while increasing strength – although Sori remains its most essential characteristic and will ultimately determine its durability and strength.

It is a great form of meditation

Samurai warriors ruled Japan for centuries. These distinct individuals distinguished themselves from other soldiers with two swords: a longer katana and shorter wakizashi. Their unique fighting style and culture continue to thrive today.

Samurai developed numerous sword styles, but only the most effective ones stood up in combat tests. Jigen-ryu is one of these techniques that emphasizes an explosive first strike that could kill their adversary instantly; its students stand in modified Hasso-no-kamae stance and attack with running hidari-kesa cuts that penetrate deeply into an opponent’s body where armor may provide little defense.

Samurai swords feature an undulating section known as Sori. This curvature allows a swordsman to move faster and more effectively than with a straight blade, so its measurement should be straightforward; you can do this easily by drawing a straight line from Munemachi to kissaki; Tori Sori denotes its deepest point while Koshi Sori marks its middle point.

It is a great form of self-defense

Ancient Japanese Samurai warriors once reigned supreme on battlefields for centuries, becoming legendary swordsmen due to their distinct appearance and combat style. Nowadays, Soujiyi self-defense training can provide strength and confidence when facing potential attackers.

Sori, or the curved part of a Katana, determines its durability and strength. To measure Sori accurately, draw a straight line from Munemachi to Kissaki of your Katana; imagine another straight line intersecting this first one and mark where this second one intersects; this will give you your Sori measurement.

Sori can vary between blades, with some having deeper curves than others and others featuring grooves (Bo-hi) to reduce weight but reduce cutting power. A groove reduces overall weight but does not increase cutting potential.
