Welcome to the 68th Annual Obukan Judo Tournament / Onchi Sensei Memorial Shiai!

This is our 98th year of Obukan Judo!  We are only 2 years away from our 100th year in 2026! Obukan Judo started back in 1926, right here in Portland, Oregon. Jigoro Kano Shihan, the founder of Judo, visited us twice. On his second visit in 1938 Kano Shihan renamed us from Portland Judo to Obukan! Our tournament is a player’s tournament, which means it’s all about you and your Judo!  We are so proud that you are here participating in our tournament and helping us celebrate the legacy of Kodokan Judo and our journey to 100 years! 

Thank you for celebrating 68 years of tournaments and 98 years of Judo with us! 

Bowing to you all, 

Rod Conduragis
Obukan Judo Dojo, President
