It might look comic but becoming a top sumo wrestler is not for the faint-hearted.

The sport, which is over 1,000 years old, requires extreme commitment: with gruelling training and an enormous diet.

But sumo is in decline.

Revenues are falling, audiences are dwindling and the sport, which was once an icon of Japanese pride, is now dominated by foreign wrestlers.
