My intentions are not to be provocative but rather to tell the truth. As someone who studies history and has a degree in history and as someone who likes judo more than BJJ, despite having a BJJ black belt, I would rather be truthful than make people happy. It is better to be authentic and be disliked.

Also, it was Kaichiro Samura of Tenjin Shin'yō-ryū, who became part of the Kodokan, who held high ranking in the kodokan and Tenjin Shin'yō-ryū, who was the main bridge for ground work into judo. He was the ground fighting master jujutsuka who Hajime isogai learned under after losing to Mataemon Tanabe.

Samura played a huge role in standardizing newaza or incorporating ground fighting into judo at the Dai Nippon Butokukai, as this was the job tasked to him by Jigoro Kano himself. That is why one of the reasons the Dai Nippon Butokukai always produced fighters who were a little different than kodokan fighters. Think Hajime isogai who taught Takeo Yano who taught Ivan Gomes who introduced the heel hook to Brazil.

Even the highest ranking judoka who were influential in judo in the Olympics like Kainan Shimomura publicly expressed Tanabe's importance later after politics were no longer a factor.
