In some places. Where I'm currently staying in, the people hold a tournament every ten years. It's a competition between the clans to see which is the strongest and originally it was a fight to the death. Nowadays, however, it's just a sport and doesn't go that extreme. The opponents can be either monsters, humans, or both, too. Either way, people get pretty pumped when watching and cheering for their team.

Personally I think it's pretty fun, but I've only really participated once. Kind of had to, but that's a different story.
