This weekend I finished making a new training tool, called the eda koppō¹. Although I’ve used improvised versions over the years during my time studying in the Bujinkan, this is the first time of making one that is suitable for training in my Chikushin group.
The eda koppō has a unique meaning that is often difficult to translate correctly in English. To explain simply, it is a short stick, originally made out of a small branch, that was devised to give the user the upper hand in a fight. Given its shape and size, the wielder can use this to attack vital areas through strikes, or assist in joint locks and throws by applying pressure on bony areas. Small in size, it is considered a good self-defense tool, as well as a kakushi buki² (hidden weapon).
It is believed that the eda koppō was developed during more peaceful times after the tumultuous warring period of Japan, when the country was unified under & ruled by the Tokugawa shogunate. Many martial schools that specialized in jujutsu used small weapons such as this to give them an edge when a more preferable weapon, such as a sword, was not readily accessible.
Example of the eda koppō in the book “Stick Fighting”, by Masaaki Hatsumi and Quitin Chambers.
This version of eda koppō is designed to be a safe training tool. It is made out of the thinner section of bamboo, and hollow through. A thick fabric is attached to both ends for softer impact. Finally, a looped cord is threaded through singularly in order to allow the eda koppō to swivel, as well as allow for different grips. This is a 1st generation design, and I’m planning on different versions, and possibly an upgrade if necessary.

This week, if things go as planned, I’ll give it a thorough test run during normal training sessions.
