Keita Sunama "Raise the pace from the first half"

Sunama said, "The players in the world were swimming at a fast pace from the first half, and I was also moving, so I swam at a faster pace from the first half. My goal is to stay in the final with Irie. I was disappointed that my result was disappointing, but I'm glad that Irie remained in the final. I want to support Japanese players so that they can play an active role. "
