The age category is decided by the age the athlete reaches during 2027, whether their birthday is in January or December. The exception: athletes must be at least 18 on the day of the competition for the Adults category, and for the U21 category in Jiu Jitsu (BJJ).

Contact Ju-Jitsu is for the Adults category only: athletes must be 18 or over on the day of the competition.

⭐ Event rule: athletes may enter more than one discipline. A Second Entry must be in a different discipline, weight category and/or age category. (JJIF normally allows only one weight category per discipline.) Moving up an age category must follow the rules on the Merging or Moving Brackets tab.

This event uses the latest JJIF rulebooks: Ju-Jitsu Fighting Rules V5.1 (2026), Jiu Jitsu (BJJ) Rules V2.8.1 (2026), Contact Ju-Jitsu Rule Book V4.4 (2026, Full Contact rules) and the JJIF Sporting Code V1.2.1. Full rules: https://www.ju-jitsu.sport/organization/about-us/downloads

Where our pages and the rulebooks differ, the rulebooks apply, except for the Flanders Open event rules marked ⭐.

Each discipline has its own tab with its kit and event rules: Sports / Fighting Jujitsu, Jiu Jitsu (BJJ, Newaza) and Contact Jujitsu. The Jiu Jitsu (BJJ) rules are similar to IBJJF but differ in scoring, permitted submissions and procedures.

Weigh in wearing shorts and a T-shirt or rash guard.
Bring valid ID. Flemish athletes must also show a valid VJJF membership (en geldig VJJF-lidmaatschap voor Vlaamse atleten).
Scales are available beforehand so you can check your weight.
Missing the registered weight means disqualification from that category, with no refund.

A coach and referee meeting is held at about 08:30 on Saturday and Sunday. It isn't compulsory but is strongly encouraged. It is the time to ask final questions, clarify procedures and discuss rule interpretations. Once competition starts, contact with referees is limited.
