Making their worlds debut, the Japanese pair excelled with their powerful leg movements at the outdoor pool and drew a huge cheer from the crowd watching on under the blazing sun.

"I was nervous before the performance but I could enjoy it," said 20-year-old elder sister Tomoka. "It's such a precious medal, I fall short of words to express it. I want to show it to my parents as quickly as I can."

Yotaro, standing 180 centimeters, has been working on his precision and it paid off.

"We believed in what we've been doing," said the 17-year-old. "It's a medal which arrived after we gave all we have and feels great."
