Tag for mock cavalry battles?

Do we have a tag that covers images that reference the sporting event mock cavalry battles (Kibasen 騎馬戦 )?

Came across post #766896 and post #788163, which at least references it with the way the characters are positioned and the rider wearing a bandanna.

Here's a couple more: post #1079677 , post #636262 (including faux horse head)

I wonder if we shouldn't also have a tag for the Sports Festival that this event almost exclusively occurs at. It would also be a good pseudo-umbrella tag for this, three legged races, bread eating contests, and sundry other events that pretty much only ever occur at such festivals.

Relay races and cheerleaders are also super common but probably would need special reason to be included in a sports festival tag, since they are more generally applicable..

sports_festival would be a good idea

As for the kibasen, might as well just tag it kibasen for now.
