As for his favorite swimmers among the bunch, Kimura said it would have to be Richard Zhao.
“Richard comes to practice a lot. The more practice, the better a swimmers will be. Richard is a perfect example of that. I really recommend to remember his name. Maria Guerrero also has a promising future. She has already become a rival to senior swimmers,” he said.

“Andrew, Julia, and Michelle will still stay with us, but their competitive careers have ended. Thank you for your hard work for such a long time. Tsunami Saipan will support you forever in your new journeys,” he said.
Kensuke conducts special training
Kimura and Tsunami Saipan were also graced recently by the presence of former national swimmer Kensuke Kimura, who is also the coach’s son.
While on holiday back home, the 2014 Oceania Championships bronze medalist conducted a weeklong special training camp for the club, now dubbed Tsunami Athlete Course.
The younger Kimura swam for four years with the Chukyo University swimming team, a Division 1 school and one of the strongest teams in Japan.
“Tsunami swimmers were given extremely hard training much like in the college team level. Kensuke will also be there to support Isaiah at Junior Olympic at the end of this month.”
In all, four swimmers completed the Tsunami Athlete Course conducted by Kensuke Kimura—Nunez, Jinang, Chen, and Ayumi Obligacion.
Coach Hiro thanked all the swimmers and their parents for a successful 2023 season.
