Sumo

Competitive Wresling dates back to at least the Original Olympic Games in Athens, Ancient Greece. Another Ancient version of Wrestling is Sumo (Japan). Modern versions include Olympic (Greco-Roman), WWE (American), Lucha Libre (Mexico), and indeed also Mud Wrestling (England) and Jelly Wrestling (Ireland) – the latter two not sanctioned.

Sumo Reference

I have it on the authority of John Gunning that this Referece website is one of the best ever. The German who compiled it went through over 100 years of Japanese Newspapers. It cnntains the results of every Japanese Sumo bout ever recorded back to early 1900s or before.
