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.

 Please come out and support Sempai on this day and  if you are willing join in on the kumite portion of his test.   As his Sensei/Teacher I am very proud!!
