Sensei Jim Onchi Memorial Shiai


It’s time again for one of the Northwest’s best and longest running judo tournaments, The 57th Annual Obukan Shia and Kata Tournament. Renamed this year as The Sensei Jim Onchi Memorial Shiai in memory of Jim Onchi Sensei (9th Dan) who passed away recently in January. As the patriarch of the Obukan dojo, Onchi Sensei has always been an integral and driving force helping to nurture, shape and grow judo here in Portland and the northwest for nearly 60 years.

Please join us this year. We’re looking forward to an exciting tournament for players of all caliber and levels of experience.
