This is a game where the participant wears the costume and tries to push each other out of a circle , either marked by a rope or a mat . The one who is pushed out of the circle loses the game .This sport is based on Sumo wrestlers of Japan. Here participant wears dresses filled with light weight poly fill , to imitate the look of the sumo wrestlers. The dress itself is made of single PVC coated polyester yarn . After couple of years , if the poly fill gets compressed , then it can be refilled to give the bulky look.
