Wikipedia Kosen Judo

Shichitei Judo (Seven imperial university's Judo)
Yuki Nakai and Shiko Yamashita have this martial arts back ground.
It's only hold at imperial university (Wikipedia (Seven imperial university)).All 7 imperial university in Japan have shichitei judo club.It's focus on grappling like Kosen Judo but difference is no "Mate (Wait)" call so just people can focus on grappling.Shichitei Judo's game hold by each school's team.So there is type of player just beat and next guy to guy,or just aim draw.When Team beat other team's 15 people,game is over.This concept make grow each competitors specialty.One fighter just aim finishes and other just aim defence for draw.
