Challenge for the Los Angeles Olympics Begins! Trampoline Athlete Ryosuke Sakai Joins Steady Japan Inc. [Athlete's Expertise] to [Everyday Self-Care]

Ryosuke Sakai (28), a trampoline athlete who competed in the Tokyo Olympics, won a silver medal at the World Championships, and has won the All Japan Championships three consecutive times, will join Steady Japan Inc. starting March 2026. While continuing to compete with the goal of winning a medal at the 2028 Los Angeles Olympics, he will also launch an initiative with STEADY to deliver the conditioning knowledge that athletes practice daily to society at large.

Steady Japan Inc. (Headquarters: Shinjuku Ward, Tokyo; Representative Director & CEO: Yuki Mori), which boasts top-class EC sales performance in Japan, has proposed home fitness/stretch products that consider the physique, mindset, living environment, and lifestyle of Japanese people by gathering customer feedback on existing products through social media and customer support since the start of its brand development in 2018. The company announced on Monday, April 6, 2026, that trampoline athlete Ryosuke Sakai will join as a contracted athlete.

Behind this decision for Mr. Sakai to join the company is a shared aspiration that both parties have reached over a long period from their respective positions. Steady Japan Inc., which continues to refine its home fitness products by listening to customer voices, upholds the vision of "realizing a society where individuals can live healthy in mind and body, and true to themselves." On the other hand, Mr. Sakai, who stands at the forefront of competition as a top athlete, has personally experienced poor blood circulation and postural deterioration during daytime work such as desk jobs, and has diligently faced his own body by stretching every hour during long-haul flights. He has cultivated a desire to "deliver what athletes do as a matter of course in their daily lives to the general public in an easily adoptable format." His words, born from his sincere engagement with the challenges of life as a consumer, even while being a competitor, naturally overlapped with the worldview that STEADY has been trying to embody through its product development.

Moving forward, he will engage in various activities to realize this vision, including appearances on STEADY's sales pages and YouTube content, and participating in the development of ongoing programs with an athlete's perspective. Furthermore, he will continue his challenge for the Los Angeles Olympics as an athlete embodying the STEADY brand on the competitive stage. STEADY, supported by over 300,000 cumulative reviews, will take a new step forward to contribute to the physical and mental well-being of more people, together with the expertise of Japan's top-class athletes.

[SLOW BUT STEADY] - The daily care and habits that athletes consistently build into their routines are filled with hints to enrich the bodies and lives of ordinary people. By joining forces, Mr. Sakai and STEADY will bridge the gap between the knowledge honed in the world of sports and everyday self-care, delivering the "wonder of moving your body" to a wider audience.

■ Ryosuke Sakai Athlete's Comment

I am pleased to announce that I will be joining Steady Japan Inc. I am truly grateful for this new stage of challenge. Through the generous support and cheers I have received, I have accumulated a wealth of experience and achievements, including participating in the Tokyo Olympics, winning a silver medal at the World Championships, and achieving three consecutive victories at the All Japan Championships. During this time, I strongly felt the value of sports and the wonder of moving one's body. I have been a long-time user of STEADY products, and their tubes, in particular, are indispensable for everything from warm-ups to training. From now on, I hope to contribute to society through trampoline and STEADY. I also want to share the conditioning methods I use in a format that is easy for everyone to adopt. Furthermore, I will continue to strive for a medal at the Los Angeles Olympics, so I kindly ask for your continued support.
