Kyokushin kaikan (極真会館) is a style of stand-up, full contact karate, founded in 1964 by Sosai Masutatsu Oyama (大山倍達) Kyokushinkai is Japanese for "the society of the ultimate truth." Kyokushin is rooted in a philosophy of self-improvement, discipline and hard training. Its full contact style has had international appeal (practitioners have over the last 40+ years numbered more than 12 million).

Judo (meaning "gentle way") is a modern martial art, combat and Olympic sport created in Japan in 1882 by Jigoro Kano (嘉納治五郎). Its most prominent feature is its competitive element, where the objective is to either throw or takedown an opponent to the ground, immobilize or otherwise subdue an opponent.

Shin Shin Ryu Iai-jutsu is a traditional Japanese sword art dating back to the feudal period.  The current Soke (Soke Yamada) is the 11th in the line, with the Hombu in Takayama, Gifu Ken, Japan.  Outside side Japan we are lead by International Remecho Carl McClafferty.  Kaicho McClafferty is a retired Chief Border Patrol Agent and teaches in the Tucson Area.

In my opinion:
The meaning of "OSU" is often over looked. Many students use this phrase in our Dojos with a casual air of tradition. As I matured in my training, OSU became more simple and clearly defined. Words from other
cultures do not always translate to English fully. I believe OSU means you have my full attention..
OSU is a very Zen mind set (no past ,future, only the moment before you). This allows you to be 100% in the moment.. It  means focus,
purpose, reaction, and maximum result of ones efforts as well as genuine and  honest respect.

Osu !

Hello. I want to comment on this quote from Sosei.

In my opinion he is advising us to be free of bias and judgment. In other words, we are most effective and in control when not pre occupied in our minds with thoughts that may distract us in the moment. This allows us to meet each new moment without "monkey chatter". When we reach self-awareness, confidence, and faith we can smile in fearlessness.

When I recall this quote by our Sosei, at first it seemed a slow and narrow existence. But, as time went by I discovered it leads to beautiful, fulfilling and more complete personal journey. To pass this on by guidance and self example is the ultimate purpose for our continued development in life. A living breathing Zen existence.
