Judo Kata Weapons - Bokken, Jo, Tanto & Pistol
Reviews

Classic Jo - Judo no Kata

Unlike the 128 cm, long Jo used in Aikido or Jodo, the Jo in Judo is shorter and measures only 100 cm. It is, therefore, necessary for the practice of the Jo Kata to possess an adapted Jo. The usual diameter allowed in competition is around 8 bu (24 mm ~ 25 mm). If you prefer a thicker model, you can contact us for a customized version.

Resolutely classic in its shape, this model is the official model for the Kata competition and can be used for the Goshin jutsu.

Varnished or unvarnished finish?
All our high-end weapons are available in varnished or unvarnished finish. The urethane coating protects the wood against moisture and temperature fluctuations and thus makes it more durable, hence no special maintenance is needed. The unvarnished finish corresponds to a camellia oil polish to obtain a wood that is more natural and pleasant to the touch but requires regular maintenance. Unvarnished weapons are more expensive because only the best timber is good enough to be kept raw.

How to Choose Your Judo Wooden Weapons

As an expert in high quality Judo equipment KuSakura also offers the best made in Japan weapons available on the market. A small catalog, representing a fine choice - adapted to the need of all Judo practitioners.

These wooden weapons are all manufactured in Kyushu, Japan. To be more precise: Miyakonojo is the region called, where the only 3 remaining wooden weapon workshops are located.

When it comes to wooden weapons, wrong storage, brittle wood, and hidden cracks can easily cause injuries. And that is why the weapons offered on KuSakuraShop are exclusively made in Japan and undergo a strict quality control before shipment. Quality intact fiber structure is what is emphasized rather than wood color. However, please note that our weapons are not selected for hard contact, but for Kata pratice.

The basic woods for solid practice weapons are red and white oak.

Bokken, Jo, Tanto & Pistol for Goshinjutsu & Kime no Kata

Goshin jutsu litteraly translates as "self defense techniques", and the idea behind this Kata is to teach self defense against grappling, strikes, a sword, a staff, a knife or a pistol. It was created after the second world war as a mean of self defense for Japanese police forces and it is partially inspired by Aikido techniques.
Kime no Kata, also known as the Shinken Shobu no Kata (litt. Kata for real fight) is much older as it dates back to the end of the 19th century. It contains both empty ended and armed techniques and is strongly oriented on self defense. Is is often said that it is the base for the Jujutsu techniques sometimes taught by Judo teachers.

The Tanto is a dagger of approximately 30 cm long.
The Tanto is used in the Goshin jutsu no Kata on techniques: Tsukkake, Choku-tsuki and Naname-tsuki. It's also used in the Kime no kata on techniques: Tsuki komi, Kiri komi and Yoko tsuki.

The Jo is a 100 cm long staff. It is significantly shorter than the Jo used in Jodo, Jojutsu or Aikido, which is 128 cm long, and longer than the Hanbo used in some ancient martial arts which is only 90 cm long. The Judo version is completely specific to Judo.
The Jo is used in the Goshin jutsu no Kata on techniques: Furiage, Furioroshi and Morote-tsuki.

The Pistol, called a "Kenju" in Japanese, symbolise the classic firearm used by the Japanese police. Most self defense schools use a model that has a hole that represent the trigger, but for safety reasons, the Judo models has no hole.
The Pistol is used in the Goshin jutsu no Kata on techniques: Shomen-tsuke, Doshi-gamae and Haimen-tsuke.

The Bokken is a wooden representation of the Japanese Katana.
It is used in the Kime no kata on techniques: Nuki kake and Kiri oroshi.
The Bokken must have a guard (a Tsuba) when performing this Kata.

Judo Weapons

Varnish Painting Versus Oil Polishing

The best way to protect your weapons from temperature changes, moisture and dryness is to varnish them. Our Japanese artisans use a very thin layer of transparent coating that covers the timber just enough to help prevent the weapon from warping.

However, non-coated weapons are available on KuSakuraShop too, because the raw surface of high quality timber is definitely more pleasant to the touch.
Where as small imperfections and splints can easily be covered and repaired with such lacquer, unvarnished weapons have to be carved from top notch Japanese quality wood. They are oiled several times before shipment to nourish the fiber. And that is what we recommend you to do roughly once a month with unvarnished weapons: Use our artisan's Camellia oil or any other maintenance or vegetable oil. This will help to keep the wood in good condition, prevents it from drying out or irregularly absorb moisture.
But keep in mind: Wood is a natural and living material, and each piece of timber reacts slightly different to the oiling process. The wood color can change significantly and usually darkens quite a bit and gets more intense.

Akagashi (Red Oak)

Akagashi, the Japanese red oak, is commonly used for the manufacture of wooden weapons. It is a bit lighter than Shirakashi (the Japanese white oak) and also a bit less dense. Because it is quite resilient to shocks, it is commonly used for contact practice (weapon against weapon) in other martial arts. It is the timber chosen by the Japanese army for their wooden weapons, and is an excellent choice for all Judo practitioners looking for standard weapons. Thoroughly chosen, this timber is also used superior and unvarnished weapons.

Shirakashi (White Oak)

Shirakashi (Quercus acutissima) is the famous Japanese white oak, that is native to the south of Japan. The best quality oak trees grow in moist soil and exposed to the sun like those in the Kyushu and Shikoku. Shirakashi timber from there is well-known for its outstanding characteristics in the manufacture of wooden weapons. The wood is particularly resilient to shocks because it is not too hard and is hence, often used as contact practice weapons for other martial arts. Shirakashi is slightly denser and heavier than Akagashi (red oak) and it is interesting to know, that unlike European oak, it floats in water. The Shirakashi timber used for these weapons is thoroughly selected and the best pieces are chosen for the unvarnished weapons offered.
