TENTIAL Announces Conditioning Support Partnership with Stanford University Baseball Team

TENTIAL Inc. (headquartered in Shinagawa-ku, Tokyo; CEO: Yutaro Nakashima; hereinafter 'TENTIAL'), which operates the conditioning brand 'TENTIAL,' announces its partnership with the Stanford University baseball team in the United States to provide conditioning support. Under this agreement, the Stanford baseball team has introduced the recovery wear 'BAKUNE Mesh' and a team co-branded 'Texswet Full Zip Hoodie' to its athletes.

The Stanford University baseball team is renowned as one of the top academically and athletically elite programs in the U.S., committed to data-driven, scientific athlete development. For this adoption, the team’s head coach, conditioning head coach, and 12 sports medical staff members rigorously reviewed scientific evidence, including clinical data provided by TENTIAL. After approximately 12 months of athlete trials and feedback collection, the products were officially adopted. This marks a significant validation of TENTIAL’s science-based product development through clinical research, now trusted and recognized within one of the world’s most elite athlete development environments.

In recent years, U.S. collegiate sports have increasingly recognized that recovery design based on data is as crucial as training volume in determining competitive advantage. For teams enduring grueling seasons with extensive travel, optimizing 'how to live as an athlete 24/7, 365 days a year' has become a top priority. TENTIAL’s mission is to 'create a health-forward society and unlock human potential,' aiming to build a society where everyone can challenge themselves authentically and reach their full potential. The company believes that human potential depends not only on ability but also on optimal physical and mental condition. However, maintaining peak condition is still often seen as exceptional. Therefore, TENTIAL reimagines everyday life from a conditioning perspective, using scientifically grounded R&D to make optimal conditioning an 'everyday norm.' This philosophy aligns perfectly with the Stanford team’s data-driven conditioning strategy, leading to this partnership. TENTIAL’s recovery wear is registered as a general medical device, designed to promote blood circulation and support fatigue recovery and muscle tension relief. Both 'BAKUNE Mesh' and 'Texswet Full Zip Hoodie' provided in this collaboration qualify as general medical devices. TENTIAL continues to develop products through clinical research partnerships with universities and research institutions, maintaining its commitment to science-backed innovation.

Comment from David Esquer, Head Coach, Stanford University Baseball Team

'Rest and recovery are among the most critical aspects of modern collegiate athletics. We monitor athlete loads with data to scientifically prevent injuries and maximize performance. Among many sportswear options, we chose TENTIAL because its technology is backed by clear scientific evidence—not just marketing claims. Before adoption, we thoroughly reviewed the scientific data with our conditioning head coach and 12 sports medical staff, and confirmed positive athlete feedback. As a partner supporting athletes competing at the world level, we trust TENTIAL for its proven evidence.'

Comment from Rintaro Sasaki, Player, Stanford University Baseball Team

'From my first-year experience of enduring a long season, I learned how crucial it is to dedicate time to recovery. This year, I’ve streamlined my training and fully redirected that time toward sleep, nutrition, and body care.

The first time I wore BAKUNE, it was shocking—'even before getting into bed, I already feel wrapped in a comforter.' The fabric feels amazing, and now it’s an essential item I carry everywhere, even on away trips. The Texswet is especially useful during long travels, and I instantly loved the Stanford co-branded design. As a Japanese athlete, I feel immense pride in being supported by a Japanese company like TENTIAL.'
