Buki Jutsu (武器術)

Bukijutsu (lettelijk 'wapentechieken') zijn technieken met handwapens zoals die in het verleden door de samurai in gevechten zijn gebruikt. Binnen Kyokushin-kan wordt Bukijutsu beoefend in de vorm van KOBUDO, de training van Okinawa's traditionele wapens voor verdediging tegen het Japanse zwaard, de Bo en Tonfa. De Shinai wordt voornamelijk ingezet bij KENDO.

Although from all the innovations and re-introductions to Kyokushin Kyokushin-kan has made in the decade since its birth, Buki Jutsu (武器術) is certainly the most dramatic when compared to the latter decades of Sosai Mas Oyama’s life. The Buki Jutsu system within Kyokushin kan is Okinawan Kobudo (沖縄古武道). The system incorporates Okinawan farming tools and weapons with a Chinese and Japanese origin. Okinawa Kobudo teaches body power rather than muscle strength. It is practiced in kata, bunkai, and kumite.

Bōjutsu (棒術), meaning 'Staff Techniques', are techniques that involve the use of staffs for close-range fighting. Staff weapons of varying lengths have been both ceremonially and combatively used since earliest times. One of the standard 5 systematized weapons of Kobudo, the Bo is the preferred favorite in many traditional martial arts schools.

Tonfa (柺術)was one of the primitive agricultural instruments utilized by the Okinawan people in their struggle against the ravaging Samurai. The Tonfa was proved to be an extremely efficient weapon. The blocking potential of this weapon is very good and an expert can whirl it at a very high speed.

Binnen Kyokushin-kan in Nederland wordt Kobudo voornamelijk beoefend met de Bo en Tonfa. Het is zelfs een examen-eis voor de DAN-graden. Daarom heb ik een warming-up, Kihon Dosa, Ido Keiko en Kata en Bunkai en een Kumite in deze rubriek uitgewerkt (ik ben begonnen met de Bo, de Shinai en Tonfa komen later).



My training and study of Kobudo includes the use and application of the following traditional wooden weapens: Bo, Shinai en Tonfa.


The Bo was derived from a farming tool called a tenbib (tin-beeb), which was used to carry buckets or bundles around on either end and came in a variety of sizes. The most common was a six-foot piece of round wood that was not tapered at both ends so it could bear a heavy load without breaking and have strength at the tips. Later it was learned to taper the ends so there would be less weight to the Bo for carrying lighter loads.

Kanken Toyama, the founder of Shudokan, studied traditional Okinawan karate, which is based upon the Japanese occupation of the islands. During that time the Japanese forbid the citizens of Okinawa to use weapons. As such, the farmers learned to use their farming tools, in this case the Bo, against the Japanese samurai. Due to being six feet long, it gave an advantage to its wielder in providing an excellent reach against a swordsman; both ends could be used as a weapon, giving it good utility in purpose and function.


My Shinai from 1986. A gift from my sensei, shihan Henny Ruberg.

The origin of the Shinai can be found in the Edo period, a division of Japanese history running from 1603-1868. It was developed when a group of swordsmen, in an effort to reduce the number of practitioners being seriously injured during practice, undertook to create a practice weapon that was less dangerous than Bokken, the hard wooden swords they were previously using.
The word “shinai,” means to bend or to flex and was originally short for shinai-take (flexible bamboo). The ancestor of the modern kendo shinai is the fukuro-shinai, which is still in use in Kroryu Kenjutsu.
Kanken Toyama’s swordsmanship background was one of the factors that led to the Shinai becoming a weapon of study in Shudokan Kobudo; studying it would also bring the history of these weapons into Shudokan.


My Tonfa's from 2017.

The Tonfa developed from two sources: 1) the grist mill handle, and; 2) the crank handle used for drawing water from a well. They were used in ancient times by farmers as a bean or rice grinder; they were also known as Tong Fa or Tuifa. Like the other farming implements, the use of this as a weapon was driven by the Japanese occupation of the Okinawa Islands. The mills and water wells were usually communal and the farmers provided their own handles just in case handles were missing. Since handles do break with usage, the farmers would bring two or more if they have a large quantity to mill. Thus having two Tonfa available were not surprising.
Kanken Toyama’s studies of weapons included the Tonfa, another weapon that could have been used against the samurai by the citizens of Okinawa.
