KUDEN! Martial Arts, Self-Defense & Survival

When the art of the Ninja exploded onto the scene in the early ‘80s here in the Western-world, everything… everywhere was about “Ninjutsu” and how it was different from nearly every other conventional (read: ‘modern’) martial art.

Ever since the art’s introduction to the Western world, it has always been easy for folks, both inside and outside the art, and especially those coming from more conventional martial arts backgrounds, to try and relate to and/or translate Ninjutsu through that lens.

It’s easy to understand physical distance, known generally as MAAI in Japanese, regardless of whether we’re talking about a carpenter or other tradesman measuring off a certain length of wood or tubing to make sure things fit, or the distance between our body and that of our assailant in a self-defense situation. It’s also one […]

Many years ago, Hatsumi-Sensei penned an article that was titled: “Pride Goes Before the Fall”.

One of my military leaders once said to me, “Sergeant Miller, hope is not a strategic plan!”.
