Aikido: The art of Kenjutsu, the Japanese swordsmanship.


Kenjutsu is well known thanks to the famous Japanese characters named "Samurai", The great loyal ancient warrior, masters of the "Katana", the Japanese Sword. They mastered the use of the sword for combat and create several sword technique for different combat situations, making them great strategists and soldier in war, some of them had enough knowledge and practice to kill their opponents with just one cut.

The samurai had a phrase "One cut, one kill" referring to the level of mastery in the wielder, killing an enemy with just one cut was a great achievement and not an easy task, also they thought that the katana had an independent soul linked to the samurai, that's why they were trained to never throw or leave their swords in other places, that was really rude and an insult to the soul in the sword that was granting service to the samurai.

The Samurai trained with a "bokken" a wooden replica of the katana but in the right hands even a bokken could be as dangerous as the katana. They practiced the correct grab of the sword, how to unsheathe and sheathe the sword in a proper way and in a lighting speed( Iaido in Japanese), how to clean a sword and how to honor the sword soul.

Kenjutsu and Aikido.

Aikido and Kenjust are different martial arts, but in the end both of them share a goal: "Mastering the technique of a certain weapons or style".

For Aikido, the sensei, instructors and students are focused in the practice of the "Taijutsu" or close quarters combat bare handed, making throws, locks, attacks and counter attacks.

In the other hand Kenjutsu is focused in the practice of mostly the Katana sword, searching for a higher level, making the sword and extension of the body with great power in the proper hands.

In the end both martial arts share one philosophy: "Being better in what we do physical, mental and spiritually", both students Aikidosha or kendosha search for the higher level of skill in their arts and both martial arts help each other.

Being an Aikido Student can be something really good, you can learn many things about, throwing, locking and subduing somebody else for self defense, mainly Aikido is a defensive martial art, but adding the technique of the Kenjutsu can boost he skills and the technique bare handed of the aikidosha making an enhancement in the progress of the student, making it easier to detect the strong points and the weak point as well.

It's recommended for every aikidosha to have one Kenjutsu class in the week, to complement the training with the Taijustsu training.

Other weapons.

In Aikido there are also other weapons than as an student you must master, those weapons are:

-The Bokken/Katana: The weapons of the samurai.

-The Jo: A short wooden staff used by the elder samurai.

-The Wakizashi: The shorter model of the katana for close quarters combat inside a house or a castle with less space to maneuver with a katana.

-The Tanto: the samurai dagger, used as the last line of defense also used in the "seppuku" or the suicidal ritual.

-In modern times also many of the schools teach how to defend yourself from guns and some other street weapons.

-Some Schools also teach the use of the Yari (spear), Naginata (curved lance) and the Yumi (bow)

The Katana.

The main weapons for a samurai was the Katana, a really dangerous and yet very important weapon in ancient time. Having a katana was a real honor because caring that weapon was a sign of status, not everyone had the permission to carry or use a katana.

The great samurai used it as an extension of the body, showing really good mastery of the sword and honoring the Bushido or "the code/way of the warrior", they were ruled by that code, trying to make the best use of their skill for their lords and master.


Bushido is integrated by seven articles or principles:

  1. Gi.- Rectitude
  2. Yu.- Courage
  3. Jin.- Benevolence
  4. Rei.-Respect
  5. Makoto.- Honesty
  6. Meiyo.- Honor
  7. Chugi.- Loyalty

The most important principles in Bushido are Meiyo and Chugi, "Honor and Loyalty above all" a samurai sacrifice their life to their Master and lived only to protect him and make him the stronger warlord.

Failing to fulfill this principles the samurai is forced to commit Seppuku, the ceremonial suicide with a Tanto, stabbing themselves in the belly, if the Lord granted them to die with honor, then another samurai or helper would cut his head off ending the suffering as soon as possible, but if the fault was severe then they would slowly bleed and suffer the whole process until death.
