PHOENIX, Arizona, May 23. MOST of the members of Japan's world championship swim team will race this weekend at the Japan Open in Kanagawa, one of the few meets the team will race in together before heading to Barcelona. On the men's side, Kosuke Hagino will be the busiest swimmer, scheduled to race in four events. He is slated to swim five individual events in the world championships.

Aya Terakawa has been doing well in 2013 in the pool, resetting her national record in the 50 backstroke at the world championship trials in March, as well as swimming the fastest 100 backstroke so far this year. She often swims fast in season, so we could see some great performances from her.
