the lineage · ultimate truth
Kyokushin means "ultimate truth." Train here and you inherit an unbroken transmission - from the founder of the style, to the original Oishi dojo in Japan, to your mat in Ellensburg.


The Founder · 1923–1994
Born Yong I-Choi in a Korean village, he earned 4th dan in Funakoshi's Shotokan by twenty, and then walked into the mountains alone. Eighteen months of twelve-hour days under freezing waterfalls, so close to quitting that his master told him to shave off an eyebrow so he couldn't bear to return to town. He came down and won the national championship.
one strike, certain death. he became the godhand.

Alone on the mountain

the keeper of the standard · 9th dan
He read Oyama's book as a schoolboy and never looked back, becoming a live-in student at Honbu. Oyama himself named Oishi's kick 'Muramasa,' after a legendary blade. He passed the 50-Man Kumite at age forty and the 70-Man at age forty-eight. When Kyokushin splintered after Oyama's death, he built World So-Kyokushin to keep the original teachings from being diluted.

Fifty years in the art. On national television he broke two baseball bats with a single shin strike, and six ten-inch ice blocks, soaked in gasoline and set aflame, with one knife-hand. He has mentored thousands across the world, served decades as North American chairman, and now represents World So-Kyokushin under Hanshi Oishi. He is also the man who wrote the Oyama history this dojo trains by.
