Yuya Yamawaki – Precision and Persistence on the Mound

Brian Eradus • May 13, 2025

At 32 years old, Yuya Yamawaki continues to rise in the fastpitch ranks as a key pitcher for the Georgian Bay Giants. Returning for another ISC season, Yuya isn’t just focused on controlling the game from the mound—he’s also determined to contribute at the plate and build on his team's past performance.

Early Start and Family Influence

Yuya’s love for fastpitch was born early. “I started playing when I was eight,” he says, “because my father played softball. He inspired me to get into the sport and pursue it seriously.” That early family connection helped lay the foundation for a disciplined and focused athlete.

Yuya’s biggest mentor? Former national pitcher Nobunori Nishimura, whose influence helped Yuya develop both technically and mentally.

The ISC Experience

Yuya first competed in the ISC World Tournament last year and described the experience as unforgettable. “The speed of the game and the intensity—it’s something you don’t get even in baseball,” he says. “It was an honor to compete against top players from around the world.”

For ISC newcomers, Yuya offers thoughtful advice:


“It’s okay to feel nervous, but try to relax. When you're enjoying the moment, you'll often perform your best.”


One of his most memorable ISC moments came simply from being on the field with elite talent from across the globe. “It was eye-opening to see the level of play up close.”

Goals for 2025

Heading into the 2025 season, Yuya is focused on improving his all-around game.
“My goal is to
win more than last time and to contribute not just as a pitcher, but at the plate too.”

He also understands the small details that make a big difference in high-stakes games. “I’m working on control, speed, and range of motion, and focusing on keeping the leadoff hitter in check—because that can shift the entire game,” he notes.

For the Georgian Bay Giants, the mission is clear:


“Achieve better results than last season, make the most of scoring opportunities, and keep runs allowed to a minimum.”


Training and Mental Preparation

Yuya’s training plan is simple but effective:

  • Pitching reps focused on control and accuracy
  • Strength and mobility exercises
  • Mental prep through visualization and staying calm under pressure

One of the best pieces of advice he’s received came from fellow Japanese national players:


“Improvement comes through consistent effort. Don’t try to be perfect—try to be better.”


Life Outside the Diamond

Off the field, Yuya enjoys fishing and watching sports, which allow him to decompress and maintain balance. He works in electrical

maintenance in Aichi, Japan, and brings that same focus and work ethic to his job as he does to softball.


Looking Ahead

Yuya sees fastpitch not only as a competitive sport but also as a way to build stronger communities.


“Softball can improve communication and contribute to a healthier society,” he says. “It teaches discipline, teamwork, and brings people together.”


As the sport continues to grow worldwide, Yuya believes the ISC can play a key role by showcasing international players, highlighting global journeys, and continuing to provide a platform for teams from every corner of the world.
