The Jo 杖 is the standard for the practice of Japanese sticks, especially in Aikido, Jodo and Koryu. The Jo’s Kanji is the symbol of the walking stick or cane.

The entire product is made of one piece of wood by Aramaki workshops, and especially, not varnished.
This Jō in Sunuke ス ヌ ケ will suit practitioners, advanced and experienced.
The Sunuke is the heart of Isu No Ki from 150 years old, its grain is fine and dense. His veins have a chocolate brown tint more or less marbled.Rare wood and superior wood essence, it is also credited with qualities of talisman or good luck charm.
The Sunuke is a beautiful essence, dense and pleasant in hand. However, it remains poorly advised for martial practice with strong contacts, its fiber being brittle.

Avoid for strong, supported and repeated contacts.

The Japanese standard Jō measures 4.21 尺 (shaku), or 127.5 cm.

Note that these measurements are however rounded because Japanese productions are made by hand by craftsmen and the measures can vary by a few millimeters.

Message from Masamune team: The productions of the Aramaki workshop are incomparable, we consider it as the excellence of the workshops formalized by the Japanese government. In other words, only three official Japanese workshops remain to date and the Aramaki workshop is the only one that can produce enough for export outside Japan.
This workshop has kept a traditional manufacturing method, especially for the selection of wood species and parts, but also thanks to a natural drying that allows to preserve the fibres and the qualities of the wood. This traditional process makes it possible to obtain resistant, robust, pleasant and durable training weapons. The finish of the Aramaki workshop is also remarkable because after the shaping of the weapons using different types of planes, the craftsmen finish the surfacing with very fine sandpaper, giving a feeling of velvet texture.

Masamune Maintenance Tips:
Wooden weapons are ideal training products, but care must be taken, knowing how to preserve and maintain them for optimal safety and preservation. Wood, although "dead", remains a reactive material to variations in temperature and especially humidity.
- Keep weapons horizontally, preserving a stable and homogeneous moisture content throughout the piece of wood.
- Keep in a room that ‘breathes’, avoid cellars, attics, car chests.
- Do not leave near a source of heat, avoid leaving near a radiator, underfloor heating, or too regular exposure to the sun.
- Do not leave near a source of moisture, avoid leaving near entrance doors or windows.

Over time and especially in practice, wood fibres can be subject to alterations, in order to prevent or at least maintain degradation, you can:
- Apply additives such as beeswax or oils (e.g. flax) to the surface with a cloth
- Soak in oil for about 2 to 4 weeks, then ‘dry’ for 2 to 4 months. This process remains quite long and tedious, it adds weight to the weapon and can vary the balance.
- In case of surface deterioration, broken fibre, splinters, sand with sandpaper. Depending on the damage, you will sometimes have to remove a lot of material, then take different grains of paper, from the coarsest (50 to 100) to the finest (600 and more).

Finally, for your own safety, the safety of your partners and those around you, never practice with a cracked or even too fragile weapon. This can cause splinters, or splinters and parts that fly off on contact with another weapon, and injure people around them.
