Kyuta Kumagai is a 10-year-old wrestling champion who at 187 pounds towers over his peers.
In 2020, he was crowned the under-ten sumo world champion, beating competition from the UK and Ukraine.
Title aside, the ten-year-old says what he enjoys most is defeating older boys in a wrestling match.
His gruelling training regime consists of a 6-day training week which includes weight lifting, swimming and track and field, in addition to training at his local club.
As far as his diet goes, Kyuta consumes 4000 calories a day.
According to his dad, all the time and money he has spent in training his champion son has been worth it.
"It's not easy, I have to spend a lot of money and time but I think it's worth investing".
