The Maeda Project - BJJ Black Belt Lineage Database

BJJ Black Belt Lineage Database

bjj black belt lineage

For years, Rolljunkie maintained the largest and most complete database of Brazilian jiu-jitsu black belts, including their lineages as part of a website we named The Maeda Project.  The Project was started in 2012 as a way to share the history and connection to the past to which everyone who trains jiu-jitsu is linked.  The database driven site featured an interactive lineage tree, search and browse tools, and a form for submitting recently awarded BJJ black belts.

Unfortunately, the amount of effort and time required to maintain the project exceeded our resources at the time and the project was shut down in 2018.

Since we took the project offline, we have received regular inquiries about the project and its status.  We understand that the black belt lineage database was a valuable resource to the jiu-jitsu community and if there is a genuine demand, then we may consider re-launching the project in 2020 so the information we have collected over the years can be accessed.  

If you would like to see the return of The Maeda Project, please leave a comment here along with any feedback you may have.
