|Available fonts (style)||4 Japanese fonts, 3 English fonts|
|Depth||The stronger the laser, the deeper the engraving. Superficial is quite discreet, standard is deep enough to stand forever, deep can go up to 1 mm depth and creates a burning effect within the engraving.|

Camellia Oil - Tsubaki abura
Made in Japan (Isu Islands)
Ingredient: 100% Tsubaki Oil
Size: M > 70 mL / L > 118 mL
This oil has been produced on the island of Toshima (Isu Shoto), off Tokyo, for more than a century. It is used by many Japanese wood workers as well as specialists in ancient blade (shinken) who are looking for a more stable oil than the Choji oil.
Treatment with Camellia oil is recommended by the craftsmen who make our wooden weapons. The regular oiling is necessary for unvarnished weapons. It is recommended also for the maintenance of Iaito and Shinken.
Utilization on wooden weapons:
Once every 2 months in the wet season, 2 times per month during dry season. For a better preservation of your weapons, it is advisable to carefully rub them with a dry cloth after each use. When you apply the oil, clean the wood surface by rubbing vigorously with a dry cloth, then apply the oil in a thin layer directly with the hand. Allow to dry.
If your weapons are not painted it will not be necessary to sand, but if they are, sanding will help the wood to absorb more oil.
Note that this Camelia oil is initialy intended for skin and hair care. We've selected this oil for it's unmatched quality: 100% pure camelia oil, no additive, cold pressed, cosmetic grade, almost odorless, and halal certified.
Product Information & Size Chart

Made in Japan (Kyushu region)
Available woods: Red Oak and White Oak
Length: custom made, from 128 cm to 151 cm
Diameter: 21 mm (7 bu), 24~25 mm (8bu), 27 mm (9bu), 30 mm (1 sun), and 33 mm (1.1 sun).

Theoretically, a Jo features the correct length for you if it reaches your armpit. More and more practitioners are aware of it and wish to acquire an adapted Jo, cut to length to experience the difference in practice.
We recommend longer Jo for practitioners over 175 cm in height. Usually, practitioners of about 180 cm will use a Jo of about 135 cm. Practitioners of about 190 cm will go up to 140 to 145 cm.
If you are of medium build or slightly smaller, we recommend to opt for 24 mm thickness, and 27 mm for stronger build (which is also more common for longer Jo).
However, it is important to understand that it is not recommended, (unless instructed otherwise by your teacher) to practice a Kata with your partner using a Jo of a different length. Indeed, a longer Jo reaches further, and affects the strength of the lever arm during the technique. The Kata will therefore be modified which is to avoid when learning, at least in the beginning. In most schools the customized Jo is for further, personal research, once the basics are mastered.
The standard thickness is 24 mm (8 bu), other models of a different thickness are mainly designed to work on Tanren (reinforcement), which is very important in some Aikido schools. The 27 mm model is very solid, making it a great Jo to practice heavy contact Kata.
Please note that the thicker a Jo is, the smaller the chance that it bends. A 21 mm diameter classic Jo or a 24 mm diameter long Jo (150 cm) might not be perfectly straight.
All the classic Jo are adapted to the practice of Aikido but also Jodo, Jojutsu and other Koryu.
- Choice of wood species: red oak and white oak only
- Diameter: 21 mm (7 bu), 24~25 mm (8bu), 27 mm (9bu), 30 mm (1 sun) and 33 mm (1.1 sun). Please note that the 33 mm requires custom planks at the workshop and the 2 months production might not be respected depending on wood availability.
- Available finish: Urethane varnish or camellia oil polish
- Manufacturing workshop: Horinouchi for varnished models, Aramaki for unvarnished models. We may use other workshops depending on wood availability.
Non varnished - Oil polish option
Urethane varnish is the "classic" finish for wooden weapons. This varnish protects the wood from moisture or drought, but the touch is less pleasant than that of unvarnished weapons. When wood is not varnished, it is necessary to treat it regularly (every two months on average) with oil (camellia, walnut oil or linseed oil). Unvarnished weapons are meticulously polished with a fine grain sandpaper, which, in addition to the oiling work done by our team before shipping, justifies the extra charge. Only quality weapons can withstand a Japanese oil finish instead of varnishing. This is the finish we recommend to the most demanding practitioners.
Please note that we do not recommend unvarnished finish for thin and long Jo as it may significantly increase the risk of bending.

*Weapons are all handmade and therefore, color and weight can vary. Due to the fact that this product is custom made, it is not possible to request for a specific weight.
We rigidly sort through all our in stock products, selecting and finally selling only what meets our standards. Of all the wooden weapons we receive, 10 to 15% are eliminated and mostly destroyed. We are proud of the fact that our quality control is the strictest on the market.
However, we cannot offer such a sorting for custom made products and those can therefore show minor flaws like a slight curvature, particularly on the thinnest Jo, of maximally 24 mm, or a finish that shows stains or color variations on the surface, particularly on the thickest Jo. Finally, the diameter of the thickest Jo (33 mm) can vary by 1 mm.
However, in case there is a major defect that we as practitioners ourselves could not accept, we, of course, will replace it, leading to an increased manufacturing time.
Last but not least, we recommend paying attention to very heavy Jo, 30 mm or more. This type of weapon can be dangerous for practitioners who do not master the techniques, by causing shoulder and back pain.
