Description
Welcome to the 2025 USJA Kosen National Championship (I know - we’re a couple of days late!). The Kosen ruleset is unique and aims to provide an even playing field for Judoka, BJJers, Wrestlers, Sambo fighters etc. to compete together. The Rules can be found at: https://www.usja.net/staff/forms/163/document/download?display=inline
This year, the Kosen Nationals will consist of a seminar on Friday, January 9th, 2026 from 6:30-8:30 (including open mat) by 4th degree Judo black belt and 2nd degree BJJ black belt Steve Matias; a featured seminar on Saturday January 10th, 2026 from 2-3 pm (kids) and 3:30-5:30 pm (adults) by 7th degree Judo black belt and 7th degree BJJ black belt Paulo Augusto; and the Kosen tournament (kids and adults) on Sunday January 11th, 2026 beginning at 11 am. ALL three events will be FREE to USJA members.
An annual or lifetime USJA membership is required for participation. An annual membership costs $75 (with family discounts available!) and can be acquired at United States Judo Association (usja.net). USJA membership not only includes the right to be promoted in Judo and to receive certifications through the USJA, but it includes individual injury insurance.
For the tournament, Senior men's, women's and master's divisions will be single elimination. An additional open weight men's, women's, and master's division is available. All other divisions will be double elimination. All competitors must wear a white BJJ or Judo gi.
