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.

Our goal at Kaizen Kan is to pass on the wisdom that was past on to us, to the next generation, to see the arts live and breath as they help improve the human qualities. These arts belong to everyone. I am a Shihan of the Bas-I Kyokushin Karate Organization and serve as the Arizona Branch Chief.

Shihan Larry

Osu ! and hello,
I am Sensei ( Lar) Swanser.
I came to begin a 35+ year journey on the path of Sosei Oyama inOctober 1979. After much discussion I and my wife were the first students in the Seattle dojo were we learned. Although we wore Seido patches on our gis we were trained in strict Oyama karate. Our Sensei had actually trained in the Tokyo Honbu on two occasions. Although we were technically Seido under Kaicho Tadashi Nakamura we remained an island of Kyokushin Kai. My best synopsis of our training is shortly viewed by watching the documentary "Fighting Black Kings"circa 1975-76. After nearly 35 years I left my Dojo and moved to Florida.

Shihan William Schrader became my kohai at age 11 years and trained with me for some 17 years. His passion and prowess was unbelievable ! I am very proud to have elevated him both 2nd and 3rd Dan. As his physical dynamics soften his wisdom replaced it. He is a very complete martial leader. I am proud to have trained with him. We are of a past generation and hope to carry the standards forward. Today's students are tomorrow's leaders.
