Reigning world champion Shohei Ono has claimed Japan's first judo gold of Rio 2016 on Monday, ending a run of five bronze medals in the sport over the first three days of the Games.

Ono beat Azerbaijan's Rustam Orujov by ippon in the men's 73-kg division to claim gold on his Olympic debut, adding it to his two world championships titles.

"I'm really happy. I am not totally satisfied with my performance but I think I was able to convey the brilliance, beauty and strength of the sport that is judo to the people watching," said Ono.
