About Lien
We will introduce the corporate philosophy, achievements, history, and company overview of Lien Co., Ltd.


What is Lien?
We are not merely a manufacturer of health and beauty products; we provide value beyond sales. Our mission is to deepen the bonds between people through our products and services, to draw out and support the infinite potential within each individual. As a company that "illuminates a corner of society," we help everyone shine to their fullest in their own place.
The word "kizuna" originally symbolized restraint or bondage—something that limited one’s freedom through ties or constraints.
What’s kizuna ?
"Kizuna" is not merely a form of restraint. True bonds are forged through mutual support and the willingness to dedicate oneself to others.
I feel that this is the key to organic success.
Corporate philosophy
Vision . Mission
~be organic, be a success~

is not merely to deliver products and services.
We strive to illuminate the world by pursuing the highest quality in everything we offer.
Our journey began with “b-ternal,” a brand rooted in enzymes—vital catalysts that sustain life and drive natural processes.
Just like enzymes, we aim to serve as a catalyst in society: creating new connections, elevating values, and delivering a world-class
quality across the globe.
We are fortunate to have formed meaningful partnerships with like-minded individuals around the world, allowing us to
continuously pursue excellence and integrity in our products and services.
More than a manufacturer of enzymes, we see ourselves as a bridge that connects the societies around the world.
Through innovation and unwavering commitment, Lien Co., Ltd. continues to challenge the status-quo and create a value that
transcends products—building a better future for all.
Inspired by the principle of “Sanpō Yoshi,”
we are committed to doing business that
brings happiness to all — the seller,
the buyer, and society.
