At 85 kilograms, Kyuta Kumagai is twice the size of the other children his age and is so dominant that he wrestles, and beats, boys five or six years older. | Above: Kyuta does a plank during a one-on-one training session at the Buddhist temple Joshin-ji in Tokyo.

He trains six days a week, either at his local sumo club or lifting weights. He also swims and practices track and field to build up the flexibility and explosive quickness needed for sumo wrestling.

Kyuta has been on the programme since his father entered him in a tournament while still in kindergarten. "I didnt teach him anything, he could do various things naturally," said Taisuke, a former amateur sumo. "There is a talent for sumo and he has that talent. He won the tournament. I thought he may have something special."

A shy boy of few words, Kyuta's motivations are simple. "It is fun to beat people older than me."

When it became apparent the boy had talent, Taisuke moved the family to the Fukagawa area of Tokyo that is famous for producing sumo wrestlers. It has an abundance of clubs and Nominosukune Shrine, where the God of Sumo is said to reside, meaning there is a lot of local support for the Kumagais.

Taisuke pushes Kyuta so hard that the child is often left breathless and crying. But he believes it is the only way to get the best out of his son.

"I think he is managing to make time for himself and I think he has time to play with his friends," explained Taisuke. "I dont think it is too much pressure."

The training is expensive and requires a huge commitment from the entire family, including his mother Makiko. "I dont do gambling (at a casino). Instead, I'm betting everything on this," Taisuke said. | Above: Kyuta carries his sister Nanami, 16, on his back at their home.

Kyuta eats steak, which his father bought him as a reward after training, at 'Chime', a restaurant in Tokyo. Key to any sumos success is their diet. On an average day, Kyuta will consume 2,700 to 4,000 calories, including over a litre of milk and copious amounts of protein. Steak is his favourite.

If he does that, the hope is he will be taken in by a high-profile sumo stable and Taisuke said there has already been interest.

"Sumo training is something you dont describe with words like enjoy," Kyuta said. "When it became tough I have thought about (quitting) sometimes." For now though, the grind towards the top continues, for both father and son. | Above: Kyuta, wears a protective face mask as he spends time with his friends at Meiji Elementary School.
