When Yuko Fujii took a job coaching judo in England after graduating from university, she didn't anticipate that she would one day be coaching the sport at an Olympics in her home country.

Fujii is now the head coach for the Brazilian men's national judo team. That means in just over one year she will bring the country's top competitors to her homeland with the aim of winning Olympic glory.

Judo is a sport that was born in Japan, but is now practiced worldwide. At the 2016 Rio Olympics, 26 different countries won medals.
