Swimming star Daiya Seto hit the pool for about an hour Monday at the National Training Center as the Olympic practice facility reopened following the end of Japan's state of emergency over the coronavirus outbreak.

The reigning world champion in the men's 200- and 400-meter individual medley resumed his campaign for gold at the delayed Tokyo Olympics next summer, completing a full-scale practice for the first time in about two months.

"I'm used to swimming in this pool every day, so it felt really natural," Seto said through his management company. "I'm still in the process of getting started, but I am progressing toward (the Olympics) next year."
