The Maeda Project
Brazilian Jiu-Jitsu Black Belt and Lineage Database - Version III
Rolljunkie got it’s start making gear and apparel for Brazilian Jiu-Jitsu players. Named after Mitsutyo Maeda, The Maeda Project was initially created as a Rolljunkie side project to document the lineage of BJJ black belts.
Since it’s inception, the Project has received significant interest and our database continues to expand.
Now on version III, the Project includes new features to go along with our interactive lineage tree such as browse and search pages.
A new contributor form has streamlined the process for adding and updating entries in our database.
We have also expanded our database to include profile information for black belts including pictures, bio & achievements, academy information, and other information.
Contributions may take several weeks before they are added to the tree/database. If we are uncertain about the validity of a contribution, we will contact you. Anonymous contributions are less likely to be added to the database.
