The boys’ team of rugby player Franc, American footballer Reef and gymnast Sol are in Japan to learn their national sport of sumo wrestling. Watched over and cheered on by presenter Karim Zeroual, at the end of the week the boys will be competing in a sumo wrestling tournament against top young locals. Today, head coach Sensai Inahara wants to teach them the importance of body positioning – key to any good sumo move. After an intense training session that involves bashing a heavy wooden pole, followed by facing an actual sumo adult expert in the wrestling ring, he takes them to a dance festival happening in town to see if they can learn some other moves. But there is a twist - their dance teacher is none other than Karim!
