International Judo Federation 2015 Regulations
All you need to know to comply with the new IJF regulation
Introduction to the IJF norms
To ensure fair competitions, the International Judo Federation has established standards that are revised annually for all Judo equipment used in competition. With the exception of the JOA model, all high end KuSakura Judogi are IJF approved under the 2015 last regulation (red label). However, it is important that the Judogi ordered suits with your size and follows a number of parameters. You can find the main points in this section, but you can also download the entire federation document on our website in PDF format. These standards are mandatory for any international competition. The regulations of each local federation can be more permissive than the IJF rules but not the opposite. To present oneself with a IJF-approved Judogi at a local or national competition ensures compliance with local standards.
Starting from April 1st, 2015, the wearing of a red-labelled Judogi is compulsory for all competitions run by the IJF. This ONLY concerns international competitions. Local rules for national and regional competitions and for grading shiai do not impose those new standards. Generally speaking, this page only applies to international standards and not to the standards of the National Federations such as the USJF (US), or the BJA (UK) .
The color of the label
Effective from April 1st, 2015, all practitioners attending an event must imperatively possess an IJF Judogi with a red label (2015). The regulations regarding the belts have not changed, those can have either a blue or a red label. It is imperative that the identification number of the IJF authorization appears on the jacket and the pants.
Belt: red OR blue logo accepted.
Judogi: red logo ONLY.
