Learning: Basic movements like Kokyu ho are applied here

Attributes: Big tatami (or normal tatami on top of the regular tatami)

This looks a lot like the sumo fun-damental, but this time you need a thick gym mat. Or you can put some extra tatami on top of the current tatami (so you will have a ‘on the mat’ and ‘off the mat’). Once everything is set, everyone goes sit on the same thick tatami. The goal is to push everyone off of it until one person becomes ‘King of the tatami’. 

Of course it’s not allowed to scratch, bite or anything mean. 

Techniques: Seiza Kokyu ho / Ryote kata dori – kokyu nage 

Tip: When they work together they can push off a senpai very easily

Warning: Make sure everyone follows the rule: “STOP’; is stopping the game. (It is very easy to push someone over, but when his/her leg is still stuck on the mat… it’s not very pleasant.)
