Japan's Nao Kusaka won the gold medal in the men's 77-kg Greco-Roman wrestling event at the Paris Olympics on Wednesday, while Demeu Zhadrayev of Kazakhstan claimed silver.

"Since I was told about the design of this medal, I thought that it was so cool and that I'd like to have it so bad," he said.

"Now, looking at it in my hand, I'm feeling so happy about this achievement, because it's mine."
