On March 16, 2026, TENTIAL Inc., headquartered in Shinagawa, Tokyo, received official validation from Tokyo Customs regarding their appeal against the importation of counterfeit items from their recovery wear series, BAKUNE. This recognition now adds these products to a nationwide list of items subject to seizure by customs authorities.
The rise of counterfeit products circulating on secondary retail sites and e-commerce platforms has become increasingly concerning, particularly as various imitations of TENTIAL’s trademarks and product designs emerge. Recognizing these counterfeit items as violations of intellectual property rights, TENTIAL is determined to confront this issue rigorously. According to Article 69-11 of the Customs Act, any goods that infringe on trademark rights are designated as prohibited imports, allowing customs to seize such items when they are detected at borders.
TENTIAL believes it is imperative to protect its brand and provide safe, reliable products to its customers. In light of this, the company has committed to opposing activities that undermine their foundation and integrity in product delivery. This aligns with TENTIAL's mission to 'Create a society that is positive towards health and bring out human potential.'
Founded in February 2018 by Yutaro Nakanishi, TENTIAL emerged from Nakanishi's personal journey. Having aspired to be a professional soccer player, he faced an illness that ended his dream during high school. This pivotal experience highlighted for him the importance of health and daily conditioning as critical components to unlock personal potential. With this consciousness, he established TENTIAL to facilitate the incorporation of conditioning into everyday life.
The TENTIAL brand emphasizes the pursuit of functionality through products and services based on insights from athletes and cutting-edge research. The company promotes conditioning activities that support physical and mental well-being, aiding in recovery and performance enhancement every day of the year. TENTIAL’s belief is to draw out individual conditions and capabilities, ultimately contributing to a healthier society through effective conditioning practices.
With a capital base of 910 million yen (as of November 2025), TENTIAL operates out of its 5th-floor office in the Garden Grace Shinagawa Gotenyama. The company is publicly listed on the Tokyo Stock Exchange's Growth segment, exemplifying its expansion in the health and wellness industry.

As they intensively fight against counterfeit products and pursue their mission, TENTIAL remains dedicated to restoring trust in their offerings and ensuring customers receive only authentic products.
In conclusion, the import ban on counterfeit BAKUNE recovery wear not only protects TENTIAL’s intellectual property but also reinforces their commitment to integrity and customer safety. Through these efforts, TENTIAL aspires to ultimately create a healthier and more empowered society, laying the groundwork for individuals to realize their fullest potential.
