Former Yaei High School Students Give Back Through Strength Training Leadership

Transforming Athletic Potential: Strength Training Initiative

In a remarkable effort to support the growth of young athletes, Daiki Yoshikawa, CEO of RIPPLE and a proud alumnus of Yaei High School in Kanagawa, took a hands-on approach by providing specialized strength training for the school's renowned soccer team. This initiative serves as a testament to the company’s core philosophy of "proving human potential" and builds on their previous contributions as an official uniform sponsor by addressing specific challenges faced by the athletes.

The Background of Support

On December 6, 2025, Yoshikawa, along with two trainers from his 17-location personal training business STREAM, visited Yaei High School to deliver targeted weight training guidance. The school has a prestigious sports science program and is celebrated for producing many J-League players. This visit emerged from an earlier collaboration where RIPPLE donated official uniforms and established a relationship with the team's coaches. During that time, the coaching staff expressed their concerns regarding the physical fitness of the players, highlighting their need for professional training to enhance their strength.

Addressing Physical Strength Challenges

The event focused on restructuring the players' training methodologies to combat physical shortcomings, particularly in situations where players face powerful opponents during matches. This concept of ‘losing strength when encountering impact’, termed as 'power loss' in soccer, signifies a common issue for athletes who possess skill but lack the physicality to apply it effectively on the field. The training session centered around the foundational 'Big Three' exercises: bench press, squat, and deadlift. These compound movements are essential in building core strength necessary for competitive play.

Under professional supervision, the athletes challenged themselves with maximum weight during assessments, as their faces reflected a mix of determination and excitement. It was evident that quantifying their progress in weightlifting transformed their perceptions of their abilities; one of the students remarked, "I can feel it working on the core of my body, and now I feel like I won't lose in a physical contest."

A Holistic Approach to Training

STREAM's training regimen is not merely about lifting heavy weights; it integrates medical insights as trainers work closely with qualified professionals to address and prevent injuries. This well-rounded approach enables the athletes to learn safer physical manipulation alongside rigorous strength training. After the session, the students appeared enthusiastic, gathered around their coaches and the trainers for a celebratory group photo, highlighting the camaraderie and knowledge shared among them.

Positive Feedback from Coaches

The head coach of Yaei High School’s soccer team expressed, "The players' eyes sparkled far more under professional trainers than under my instruction. Their experiences with direct guidance from industry professionals provided invaluable learning moments. I hope this support continues, as it greatly benefits our team."

Looking Ahead

As RIPPLE targets an ambitious revenue goal of 1.5 billion yen this fiscal year, escalating to 4 billion next year, STREAM's growth trajectory is impressive with strategic expansion plans for up to 32 locations by 2026. Yoshikawa is committed to applying the lessons learned from Yaei High as a model for future outreach initiatives, aiming to strengthen ties with local schools and sports teams through community-oriented support and training programs.

The concept behind STREAM is about more than just fitness. It aspires to be a pillar of health within the community, fostering the next generation of talent by maintaining an unwavering focus on health and athletic excellence. The personal training facility is dedicated to providing an exceptional and accessible fitness experience, reflected in their expansive gym layout and professional, medically-informed trainers.
