Everyone says BJJ started with Maeda. It goes deeper.

1882: Jigoro Kano founds the Kodokan in Tokyo.
Tsunejiro Tomita is his FIRST student, line 1 of the enrollment book.
Maeda learns from Tomita and takes judo to Brazil, where Carlos Gracie learns in Belem (historians still argue: from Maeda himself or from his student Jacyntho Ferro). Helio learns from his brother Carlos.
.. Your coach ... YOU?
